Global Trade Liberalization Trends and Developments Since 2017: A Comprehensive Overview
Introduction and Context
The period from 2017 to 2024 has been tumultuous for global trade. After decades of steady liberalization, a wave of protectionism and trade tensions emerged, epitomized by tariff wars and rising barriers. At the same time, many countries pushed forward with new trade agreements and reforms to keep markets open. This juxtaposition of escalating trade wars and continued calls for liberalization defines the era . Notably, World Bank Chief Economist Indermit Gill has warned that soaring tariffs and retaliation are compounding economic woes – and has urged countries to proactively liberalize trade and cut tariffs to avoid a damaging spiral of retaliatory trade wars . This report provides a detailed overview of global trade liberalization trends since 2017, covering key events, agreements, case studies, influencing factors, data on tariffs and trade volumes, and the growing consensus on the need to revive open trade. It draws on 200+ reputable sources – including research papers, policy reports, and news articles – to ensure an evidence-backed analysis.
Indermit Gill’s Call for Proactive Trade Liberalization
World Bank Chief Economist Indermit Gill has emerged as a prominent voice calling for renewed trade liberalization. In April 2025, amid heightened trade tensions, Gill sounded the alarm that “spiking trade uncertainty” – driven by a “tsunami of tariffs” – was undermining growth prospects . He noted that U.S. tariff rates had climbed to their highest levels in a century, prompting retaliatory duties from China, the EU, Canada and others . Gill argued that if governments “cut their own tariffs”, they could give a significant boost to growth and help stave off escalating tit-for-tat measures . In his view, the current trade shocks are self-inflicted – a result of policy choices – and thus can be reversed by policy choices . This reflects a broader consensus among economists that proactive liberalization now could prevent an entrenched trade war dynamic later . Gill’s warnings echo those of other global institutions urging cooperation: for example, the WTO has pleaded for “strong collective leadership” to roll back restrictions and avoid a slide into protectionism . His statements set the stage for why examining trade liberalization efforts (and setbacks) since 2017 is so critical.
Rise of Protectionism and Trade Wars (2017–2022)
U.S. Trade Policy Shift and Tariff Escalation
In 2017, the United States – long a champion of free trade – abruptly shifted toward protectionism under the Trump administration’s “America First” agenda. One of President Trump’s first acts was to withdraw the U.S. from the Trans-Pacific Partnership, signaling a retreat from multilateral trade deals . Soon after, the U.S. turned to aggressive tariff measures. In 2018, it imposed sweeping tariffs on steel (25%) and aluminum (10%) imports globally on national security grounds . Major trading partners retaliated in kind: for example, the EU targeted iconic American products (bourbon whiskey, motorcycles, jeans) with equivalent tariffs , and Canada and Mexico applied levies on U.S. farm and consumer goods .
By mid-2018, the U.S. had also launched a bilateral trade war with China. Citing unfair trade practices, the U.S. applied Section 301 tariffs on Chinese goods in several tranches: $34 billion in July 2018, $16 billion in August, and $200 billion in September . Tariff rates on the $200 billion list were initially 10%, later rising to 25% by May 2019 . China retaliated proportionally, slapping tariffs on about $110 billion of U.S. exports (including soybeans, autos, and energy) . By late 2019, average U.S. tariffs on imports from China had surged from just 3% pre-trade war to over 20% – the highest since the 1930s . Nearly 97% of Chinese goods entering the U.S. faced extra duties . Beijing’s average tariff on U.S. goods likewise jumped from around 8% to over 20% . This marked a dramatic reversal of decades of tariff reduction – effectively undoing, in two years, a substantial portion of post-WTO liberalization .
The tit-for-tat spiral expanded beyond the U.S.-China dispute. The U.S. threatened or imposed tariffs on allies as well – including duties on autos and parts (which were later paused) and a brief tariff spat with Mexico over immigration policy (quickly rescinded) . Trading partners filed complaints at the WTO and enacted counter-tariffs. By 2019, the EU and U.S. were also entangled in a longstanding Boeing/Airbus subsidies case, imposing punitive tariffs on each other’s exports (though a truce was reached in 2021). In sum, 2018–2019 saw an unprecedented surge in trade restrictions globally. The WTO documented that from mid-2018 to mid-2019, G20 economies implemented 102 new trade-restrictive measures covering $747 billion of trade – “the highest recorded figure since 2012,” according to its monitoring report . This was 27% higher in trade coverage than the prior year, which was already elevated . WTO Director-General Roberto Azevêdo described the situation as “extremely serious,” warning that escalating barriers threatened to derail global growth .
WTO Under Strain and Erosion of Multilateral Rules
The onslaught of unilateral tariffs also strained the multilateral trading system. The World Trade Organization’s dispute settlement mechanism – traditionally the backstop against protectionism – was effectively paralyzed in December 2019 when the U.S. blocked new appointments to the WTO Appellate Body, preventing it from hearing appeals . This meant there was no binding enforcement for WTO rules at the height of trade conflicts. Many countries were left to negotiate bilaterally or resort to self-help measures rather than rely on rule adjudication. The breakdown of the WTO’s appellate court – described as “the WTO’s crown jewel” – raised fears that countries would increasingly ignore WTO disciplines . Indeed, the period saw rising resort to bilateral retaliation and ad hoc arrangements. Experts noted that the predictability and certainty of the trading system was eroding, making long-term business planning more difficult . WTO data showed global trade growth slowing markedly as a result (detailed in a later section). In short, the late 2010s represented a stark departure from the cooperative liberalization of previous decades, as major powers opted for protectionist tactics. This set the stage for a bifurcated global response – with some doubling down on openness even as others raised walls.
Regional Trade Agreements Forge Ahead (2018–2023)
Even as trade wars grabbed headlines, many countries responded by pursuing new trade pacts and liberalization at the regional level. These agreements aimed to lower tariffs, harmonize rules, and keep markets open – often filling the void left by a retreating United States.
Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP): In March 2018, 11 Asia-Pacific countries – including Japan, Canada, Australia, and Vietnam – signed the CPTPP, salvaging the erstwhile TPP after the U.S. withdrawal . This sweeping pact was a “landmark…powerful signal against protectionism and trade wars,” declared Chile’s president at the signing . The CPTPP links economies comprising 13% of global GDP (about $10 trillion) and eliminates tariffs on 95–99% of goods trade among members over time . It also sets high-standard rules on services, investment, intellectual property, and labor and environmental standards (many carried over from the original TPP) . The agreement took effect at end of 2018 after six members ratified it, and others followed in 2019 . Notably, Japan led the remaining members in pushing CPTPP forward, signaling commitment to open markets despite U.S. absence . By keeping the pact alive, these countries prevented the dissolution of what the Peterson Institute called “the highest-standard trade agreement in existence”. In subsequent years, the CPTPP began expanding: the UK formally signed on in 2023 as the first new member, and economies like Taiwan, South Korea, and even China have expressed interest in joining, underscoring its magnetic pull .
Regional Comprehensive Economic Partnership (RCEP): On November 15, 2020, fifteen Asian and Pacific nations signed RCEP, creating the world’s largest free trade bloc by population and GDP . RCEP brings together all 10 ASEAN countries plus China, Japan, South Korea, Australia, and New Zealand – a grouping covering ~30% of global GDP and 2.2 billion people . It is the first-ever trade agreement to include China, Japan, and South Korea together. The pact aims to eliminate about 90% of tariffs within 20 years and establishes common rules on investment, e-commerce, and intellectual property . While considered less comprehensive than CPTPP (RCEP has more limited provisions on services, labor, and environmental standards) , it is a significant liberalization step for the region. RCEP’s signing was seen as a geopolitical win for Asia and especially China – cementing regional economic integration at a time the U.S. was absent from such initiatives . Analysts noted RCEP could “pull the economic center of gravity toward Asia,” as members benefit from easier trade and simplified rules of origin across the bloc . The agreement entered into force on January 1, 2022 for the initial ratifiers. While India opted out of RCEP negotiations in 2019 due to domestic market fears, the door remains open for its future accession . RCEP’s implementation is gradual, but its sheer scale makes it a cornerstone of trade liberalization in the 2020s.
United States–Mexico–Canada Agreement (USMCA): In North America, even the protectionist U.S. agreed to an updated trade pact to preserve continental integration. The USMCA, signed in late 2018 and in force by July 2020, replaced NAFTA while largely maintaining its tariff-free market access . The new deal introduced stricter rules of origin for autos (75% North American content, up from 62.5% in NAFTA) and labor wage requirements in auto production , aiming to bring more manufacturing onshore. It also updated chapters on digital trade, intellectual property, environment and labor (partly to address criticisms of NAFTA). Although USMCA was driven in part by U.S. threats to withdraw from NAFTA entirely, the end result was a reaffirmation of free trade in North America – described as “NAFTA 2.0.” Tariffs remained at zero on most goods traded among the U.S., Mexico, and Canada , preserving a ~$1.2 trillion trilateral trade zone. In effect, USMCA represented a managed liberalization: new provisions modernized the rules (winning bipartisan support in the U.S.), even as higher regional content rules and a 16-year sunset clause added managed trade elements. Still, its enactment during a trade-war climate sent an important message that North America would remain an integrated market .
African Continental Free Trade Area (AfCFTA): In March 2018, African leaders signed the AfCFTA agreement, and by January 1, 2021 it officially launched – creating potentially the world’s largest free trade area by number of countries (54 nations) . The AfCFTA aspires to unite a $3.4 trillion market and boost intra-African trade by removing tariffs on ~90% of goods over 5-10 years and liberalizing key services . It also seeks to address non-tariff barriers and improve customs cooperation across Africa. The World Bank estimates that if fully implemented, AfCFTA could boost Africa’s income by $450 billion (7%) by 2035 and lift 30 million people out of extreme poverty . About two-thirds of the gains would come from reducing non-tariff red tape through trade facilitation measures . This ambitious project reflects Africa’s commitment to liberalization as a path to industrialization and growth. Early progress has been slow – negotiations on tariff schedules and services commitments are ongoing, and actual trade under AfCFTA preferences remains modest so far. Some hurdles have appeared, such as Nigeria’s sudden closure of land borders in 2019 to curb smuggling (just after signing AfCFTA) . However, Nigeria reopened borders by end-2020, and overall, AfCFTA has strong political support. As implementation continues, it represents a major proactive liberalization effort, aiming to double intra-African trade by 2030 through removal of barriers . The AfCFTA stands out as a continental initiative to liberalize trade, countering the global protectionist trend.
Other Notable Agreements: The European Union advanced its own trade network, signing deals with Japan (entry into force 2019) and Vietnam (2020), among others. The EU-Japan Economic Partnership Agreement created an open trading zone covering ~30% of world GDP when it took effect . Japan and the EU eliminated nearly all tariffs between them, a clear rebuke of protectionism. The EU also concluded an FTA with Mercosur (Brazil, Argentina, etc.) in 2019, though ratification stalled over environmental concerns. In the wake of Brexit, the UK negotiated new FTAs – notably with the EU itself (the 2020 Trade and Cooperation Agreement ensuring zero-tariff, zero-quota trade in goods) and with partners like Australia and New Zealand (2021) – and joined the CPTPP in 2023 . These moves were intended to liberalize the UK’s trade beyond Europe, although Brexit simultaneously introduced new barriers between the UK and EU. Additionally, subsets of WTO members pursued plurilateral deals: for example, a Digital Economy Partnership Agreement (DEPA) among Singapore, Chile, and New Zealand (2020) to set rules facilitating digital trade, and a WTO Information Technology Agreement expansion (2015) eliminating tariffs on high-tech products (implemented in these years) . While narrower in scope, such agreements all contributed to keeping the flame of liberalization alive.
In summary, regional and bilateral liberalization accelerated even as multilateral efforts stagnated. Economist agreements like CPTPP, RCEP, and AfCFTA indicate that many nations chose integration over isolation. As one analysis noted, these pacts sent “a strong message…that open markets, economic integration and international cooperation are the best tools for creating prosperity.” Together, they have knitted together large portions of the globe under updated trade rules, partially offsetting the protectionist actions of a few large economies.
Case Studies: Liberalization Successes and Setbacks
Success Stories – Countries Embracing Open Trade
Vietnam: Vietnam exemplifies a country that aggressively liberalized trade in this period and reaped substantial benefits. Already an export dynamo, Vietnam doubled down on free trade by joining CPTPP in 2018 and implementing the EU–Vietnam FTA (EVFTA) in 2020, among other deals. These agreements slashed tariffs on Vietnam’s exports (textiles, electronics, agricultural products) and strengthened its access to major markets . When the U.S.–China trade war erupted, Vietnam’s open economy was ideally positioned to gain: manufacturing investment and supply chains shifted its way to sidestep U.S. tariffs on China. Indeed, by 2019, Vietnam was widely cited as a “trade war winner” – its exports to the U.S. surged over 25% that year as companies diversified away from China . A research study by UNCTAD in 2019 found that Vietnam captured the largest share of the trade diverted by the U.S.–China tariffs, especially in electronics and furniture. Vietnam’s average MFN tariff rate had already fallen to around 2% (among the lowest in ASEAN) due to earlier WTO commitments , and its FTAs further liberalized specific sectors. The payoff has been robust: Vietnam’s economy grew ~7% annually pre-pandemic, poverty continued to decline, and its global export rank climbed. By keeping its doors open, Vietnam integrated into regional supply chains (for instance, exporting high-tech components to CPTPP partners and importing intermediate goods tariff-free), reinforcing its status as a manufacturing hub . This success underscores how small- and mid-sized economies can leverage liberalization to spur growth, even amid superpower trade conflicts. As a result of these policies, Vietnam’s trade-to-GDP ratio hit one of the highest in the world (over 200%), and foreign investors increasingly chose Vietnam for export production . In short, Vietnam used new free trade agreements as an engine for development – a clear liberalization success story of the late 2010s.
Japan: Japan took a leadership role in keeping trade open after 2017, emerging as a champion of liberalization in the Asia-Pacific. When the U.S. abandoned TPP, Japan rallied the remaining members to forge the CPTPP . At the same time, Japan pursued a landmark deal with the EU – the EU-Japan EPA (effective 2019) – which eliminated almost all tariffs between two economies accounting for ~$150 billion in annual trade . Japan also joined RCEP, linking it for the first time in an FTA with China and South Korea. Domestically, Japan undertook reforms (like adjusting agricultural policies) to meet high-standard trade deals, reflecting a strategic decision to integrate with global markets despite domestic sensitivities. These efforts have paid dividends: Japanese exporters gained easier access to fast-growing Asian markets and European markets, offsetting trade uncertainties elsewhere. By 2021, over 20% of Japan’s trade was conducted under CPTPP or the EU deal, helping Japanese companies remain competitive . Japan’s proactive liberalization stands in contrast to the inward turn of other advanced economies. Its success suggests that committing to trade openness can bolster economic resilience. Indeed, Japan largely avoided the tariff tit-for-tat and instead solidified itself as a linchpin of regional trade rules – enhancing its economic influence. The country’s steady growth and low unemployment in recent years, even as global trade faced headwinds, underscore the stabilizing role of these liberalization initiatives.
Sub-Saharan Africa Reformers: In Africa, countries such as Rwanda and Ghana illustrate the potential gains from lowering trade barriers. Rwanda, a landlocked country, unilaterally cut many tariffs and simplified cross-border trading processes in the late 2010s, aiming to become a regional trade logistics hub. It consistently ranks high in Africa for ease of trading across borders. Similarly, Ghana implemented the WTO Trade Facilitation Agreement (in force 2017) diligently – streamlining customs clearance – and stood to benefit early from AfCFTA by positioning Accra as the host of the AfCFTA Secretariat. These reforms have encouraged greater intra-African commerce: e.g. Rwanda’s exports to neighbors in the East African Community (EAC) climbed as customs posts became more efficient, and Ghana has attracted manufacturing investment intending to serve West African markets tariff-free under AfCFTA . While it is early days, such reform-oriented economies demonstrate how domestic liberalization and regional agreements together can spur trade and investment. According to the World Bank, countries that improve trade facilitation under AfCFTA (cutting red tape at borders) could reap two-thirds of the potential income gains . These case studies highlight that even smaller or developing countries can be successful liberalizers – using open trade policies to drive diversification, job creation, and technology transfer.
Setbacks and Challenges – Protectionist Turns
United States: The U.S. stands out as a case where a turn toward protectionism had mixed outcomes and global repercussions. By raising tariffs on a scale unseen in decades (average tariff on imports doubled from ~1.5% in 2017 to over 3% by 2020 ), the U.S. did achieve some policy goals – for instance, it pressured Canada/Mexico into tweaking NAFTA via USMCA, and China agreed to a “Phase One” deal in Jan 2020 pledging large purchases of U.S. goods . However, studies show U.S. consumers and importers bore most of the costs of the tariffs (with higher prices) , and many targeted manufacturing sectors (like steel-using industries) actually lost jobs due to higher input costs. American farmers suffered export losses until bailout payments provided relief . Moreover, trading partners’ retaliation hit U.S. exports from agriculture to motorcycles, creating pain in export-reliant communities. By 2019, the trade war contributed to a sharp drop in U.S. manufacturing output and investment, nearly tipping the industrial sector into recession . Internationally, the U.S. shift emboldened protectionist elements in other countries, weakened the WTO, and did not decisively shrink the overall U.S. trade deficit (which remained high). While the Biden administration (2021–present) toned down the rhetoric, it left most tariffs in place – reflecting the domestic political difficulty of reversing course. Thus, the U.S. case shows a clear setback for liberalization, with higher tariffs becoming “the new normal” (as of 2024, U.S. tariffs on Chinese goods still average ~19% and on global imports ~3% vs ~1% in 2017) . The longer-term consequence is reduced U.S. leadership in trade liberalization and a fragmented global trade landscape.
India: India presented a paradox in this period – a rapidly growing economy that nonetheless increased protectionist measures. From 2018 onward, the Indian government raised import duties on a range of goods (electronics, appliances, toys, auto parts, etc.) as part of its “Make in India” and self-reliance push. By 2020, India’s average applied tariff had climbed to 17.6%, one of the highest among G20 economies, up from about 13% in 2015 . In November 2019, India made the pivotal decision to withdraw from RCEP negotiations, fearing the pact would lead to surging imports (especially from China) that could hurt domestic industry and agriculture . This marked a significant liberalization setback – India forewent the opportunity to lock in access to a huge regional market. Domestically, protectionism offered short-term relief to certain sectors (e.g. higher tariffs spurred assembly of cell phones in India, reducing imports ). But economists argue India’s inward turn could undermine its longer-term growth potential by raising input costs and deterring foreign investment. For instance, automotive and solar industries in India have seen cost increases due to import duties on components, affecting competitiveness. India’s trade policy reversal also meant missing out on integration into Asian supply chains during a crucial period. Its exports as a share of GDP have stagnated around 18%, trailing peers. By contrast, countries like Vietnam (which India competes with) embraced FTAs and saw export-to-GDP rise above 100% . The Indian case illustrates how domestic political economy (pressures from farmers and small manufacturers) can stall liberalization, even in a fast-growing market. Recently, there are signs of rethinking – India is negotiating new limited trade deals (with Australia, UAE, UK) and may revisit RCEP under certain conditions – but overall, 2017–2022 was a period of retrenchment for India on trade.
Brexit – United Kingdom and European Union: The United Kingdom’s exit from the EU in 2020 provides a case of trade liberalization in reverse – at least with respect to its largest trading partner. Brexit introduced an array of new barriers between the UK and EU: customs declarations, regulatory checks, and an end to frictionless services trade. While the UK-EU Trade and Cooperation Agreement averted tariffs or quotas on goods, non-tariff hurdles have caused UK-EU trade to recover more slowly and at higher cost than if the UK had remained in the single market . Many UK exporters (especially small firms) struggled with the new bureaucracy, effectively a de-liberalization relative to pre-2019 conditions. At the same time, the UK pursued an independent trade policy: it quickly rolled over dozens of FTAs that the EU had (to maintain continuity) and struck new agreements with partners like Australia and New Zealand that modestly liberalize trade (including phased tariff elimination on most goods) . The crown jewel of post-Brexit trade policy was the UK’s accession to CPTPP in 2023, which will reduce tariffs on UK trade with eleven Pacific Rim nations and set common rules . These moves partially compensate for lost EU market integration, but most analyses (including the UK government’s own) project a net negative trade impact from Brexit. Essentially, Brexit represents a setback to regional liberalization – the first time a major economy left a free trade area. In the long run, the UK will test whether bilateral and plurilateral deals can make up for the higher costs of leaving a deep regional market. For now (2017–2024), the immediate effect was increased frictions and uncertainty in UK-EU commerce, proving that liberalization gains can indeed be reversed.
Nigeria: An example from Africa of backsliding was Nigeria’s 2019 border closure. In August 2019, Nigeria abruptly closed its land borders with neighbors (Benin, Niger, Cameroon), banning all overland import/export of goods . The unilateral move – aimed at stopping smuggling of rice, fuel, and other items – disrupted cross-border trade flows in West Africa. Nigerian consumers faced higher food prices, and neighbors’ economies were hurt (Benin relied on Nigeria for much of its exports). The closure seemed to contradict the spirit of AfCFTA, which Nigeria had signed just a month prior. It highlighted the tension between regional commitments and domestic pressures: local rice farmers lobbied for protection, and the government acted, even at the cost of regional cooperation. Although Nigeria reopened borders in December 2020 , the episode underscored the implementation challenges ahead for African liberalization. It was a reminder that political will can falter when short-term domestic interests are at stake – a setback that African institutions will need to manage to realize AfCFTA’s full potential.
These case studies illuminate the uneven progress of trade liberalization since 2017. Countries like Vietnam and Japan demonstrated the gains from openness, while others like India and Nigeria illustrate how easily protectionist impulses can win out. The U.S. and Brexit cases show that even developed economies are not immune to reversing liberalization, often with costly consequences. Overall, the lesson is that sustaining an open trade stance requires navigating complex political economy dynamics – but the long-term payoffs (as seen in the success stories) can be substantial.
Economic and Geopolitical Factors Influencing Liberalization
The trajectory of trade liberalization in recent years has been heavily influenced by broader economic, political, and geopolitical factors. Understanding these forces helps explain why some liberalization efforts succeeded and others stalled.
Populism and Domestic Politics: A wave of populist politics in many countries in the late 2010s cast trade globalization as a culprit for job losses and inequality. In the U.S., this manifested in a protectionist administration explicitly aiming to reshore manufacturing jobs via tariffs. Similar sentiments appeared in the UK’s Brexit vote (desire for economic sovereignty) and in parts of Europe (rising skepticism towards EU trade deals, e.g. with Canada and Mercosur). Politicians catering to disaffected workers found tariff protection and economic nationalism to be compelling messages . This political climate made new liberalization initiatives more difficult – trade negotiations were often portrayed as threats to sovereignty or local industry. Even where trade agreements were pursued, they had to be packaged carefully. For example, USMCA included strong labor and auto content rules to satisfy U.S. union concerns, and the EU-Mercosur FTA has faced ratification hurdles due to farmers’ and environmentalists’ worries. In emerging economies too, fears of import competition (as in India or South Africa) sometimes overrode the technocrats’ liberalization agendas. Thus, domestic political shifts toward economic nationalism slowed the pace of liberalization and, in some cases, led to reversals. That said, not all politics moved in this direction – countries with political consensus on the benefits of trade (e.g. Singapore, New Zealand, Chile) continued to champion and sign agreements. Overall, the period underscored that trade policy is deeply political: public perceptions of winners and losers from globalization directly influenced governments’ willingness to open markets.
Global Economic Climate and Inequality Concerns: The sluggish recovery after the 2008 financial crisis and the persistence of income inequality in many nations provided fertile ground for protectionist arguments. While aggregate gains from trade are positive, the unequal distribution of those gains became a flashpoint. In advanced economies, many manufacturing communities experienced long-term decline (often attributed, rightly or wrongly, to import competition). This fueled demands for tariffs or trade agreement renegotiations to protect jobs. Economists note that inadequate domestic policies (like worker retraining or social safety nets) amplified the backlash against trade . Consequently, even centrist leaders became more cautious on trade – e.g. France’s president delayed EU trade deals pending review of environmental and social impacts, and the U.S. Democratic Party in 2020 firmly opposed new FTAs without major domestic investments first. Additionally, after 2018, global growth slowed and manufacturing entered a downturn (exacerbated by trade tensions). This weaker macroeconomic environment made it politically harder to liberalize (since opening markets when domestic industries are soft can be unpopular). Paradoxically, it’s during downturns that liberalization could stimulate growth, but politics often pushes toward protection in such times. The COVID-19 shock in 2020 further upended the economic context: initially, it caused nations to impose export curbs on medical supplies, highlighting a zero-sum mindset. However, once the acute phase passed, there was recognition that keeping trade open was vital for recovery – for instance, trade helped ramp up and distribute COVID vaccines globally . The pandemic and its aftermath thus introduced new complexity: it reinforced some protectionist narratives (e.g. about reliance on foreign supply), yet also demonstrated that global trade is indispensable for resilience (diversifying sources, etc.).
Geopolitical Rivalries and National Security: Geopolitics became a major driver of trade policy in this era. The U.S.–China strategic rivalry deepened, and trade measures became a tool of great-power competition. The U.S. not only imposed tariffs on China but also sweeping export controls to restrict China’s access to cutting-edge technologies (like semiconductor chips in 2022) – a form of targeted “tech decoupling.” In response, China pursued self-sufficiency in tech and sought closer trade ties with other partners (RCEP, Belt and Road) to hedge against U.S. pressure . This rivalry has led to talk of “fragmentation” of the global trading system into blocs – a stark reversal of liberalization if it fully materializes. National security considerations started overtly trumping free trade arguments: for example, many countries tightened rules on foreign investment and exports in sensitive sectors (5G equipment, rare earth minerals, medical supplies during COVID). The concept of “friend-shoring” emerged, with leaders like Janet Yellen (U.S. Treasury Secretary) suggesting that countries should trade and invest more with trusted allies and less with strategic rivals, to secure supply chains . While friend-shoring still implies trade liberalization (but on a selective basis), it marks a shift from nondiscriminatory global free trade to a more geopolitically gated version. The Russia-Ukraine war from 2022 further injected geopolitics into trade: Western sanctions on Russia severed many trade ties (energy, finance, goods), and Russia in turn cut off some exports (like gas). Europe had to rapidly reorganize its energy trade (e.g. importing LNG from the U.S. instead of pipeline gas from Russia), and global food trade was disrupted. These shifts, driven by war, are not traditional “liberalization” or “protectionism” per se – they are coercive measures – but they have reinforced the narrative that economic security is as important as economic efficiency. Governments are now scrutinizing supply chain dependencies (for medical gear, semiconductors, critical minerals), and some are adopting policies to on-shore or friend-shore production even if it means higher costs. This environment complicates future liberalization: any new trade deal or WTO reform must grapple with exceptions for national security and the reality of great-power tensions.
Technological Change and Services: Technology has altered the landscape of trade, creating new opportunities and challenges for liberalization. The rise of digital trade (e-commerce, cloud services, cross-border data flows) means that trade agreements increasingly need to address data localization, digital services, and intellectual property in tech. Some countries imposed digital barriers (like data server localization requirements or tariffs on digital products) which require new liberalization efforts to remove. Plurilateral talks on an e-commerce agreement at the WTO and digital economy agreements among smaller groups aimed to fill this gap . The digital realm is an area where protectionism could fragment the internet (the concept of a “splinternet” with separate spheres of digital trade). Liberalization efforts thus expanded to include digital trade rules – for example, CPTPP and USMCA have chapters that ban data localization and customs duties on electronic transmissions . If widely adopted, such rules liberalize the flow of digital services and information. However, differing views on data privacy and security (EU vs U.S. vs China) mean that a one-size global liberalization is tough. Still, technology generally facilitates trade (e.g. digital platforms help small businesses export), and during COVID, digital trade boomed even as physical trade faltered. This has put services trade liberalization on the agenda: countries see potential to grow via services (finance, telecom, IT, professional services) exports if barriers (like licensing restrictions, foreign equity caps) are eased. Indeed, a WTO study noted that reducing services restrictions could boost GDP significantly. Yet progress is slow – the Trade in Services Agreement (TiSA) talks stagnated, and most services opening occurred through individual FTAs or unilateral reforms. The net effect is that technology is pushing trade liberalization into new domains, but also requiring solutions to new protectionist tendencies (like digital protectionism).
Climate Change Policies: Climate considerations have begun intersecting with trade liberalization efforts. On one hand, environmental provisions are increasingly included in FTAs (for example, CPTPP and USMCA have chapters discouraging environmental deregulation and illegal wildlife trade). Liberalization of “green goods” – removing tariffs on solar panels, wind turbines, etc. – has been promoted to facilitate the clean energy transition. An Environmental Goods Agreement was negotiated among some WTO members (though not concluded as of 2024) aiming to eliminate tariffs on dozens of green products . On the other hand, climate policies can act as trade barriers: the EU’s planned Carbon Border Adjustment Mechanism (CBAM) will impose charges on carbon-intensive imports, which some trading partners perceive as protectionist. This could trigger disputes or require new rules to reconcile climate action with trade rules. Thus, climate change is a double-edged factor – it necessitates new forms of cooperation (liberalizing trade in clean tech, harmonizing standards) even as it spurs novel trade frictions. The coming years will need creative liberalization strategies that align with climate goals (sometimes termed “climate-friendly trade liberalization”). Already, we see green alliances (like the Agreement on Climate Change, Trade and Sustainability between New Zealand, Costa Rica, Fiji, etc.) which aim to remove fossil fuel subsidies and lower tariffs on environmental goods . Geopolitically, climate has also become part of competition – e.g. the U.S. Inflation Reduction Act (2022) subsidizes domestic clean tech but has been criticized by EU and others as discriminatory to foreign producers. Addressing these tensions will be crucial to maintaining a liberal trading system.
In summary, economic and geopolitical currents have deeply influenced the pace and direction of trade liberalization since 2017. Domestic political backlash against globalization slowed or reversed liberalization in many places, even as other countries doubled down on open trade as a development strategy. Great-power rivalry introduced a security lens that complicates broad liberalization, tending instead toward regional blocks or selective openness. Economic shocks like COVID-19 and the war in Ukraine tested the resilience of open trade – initially causing protectionist reflexes, but ultimately underscoring the importance of diversified trade networks. These factors suggest that while the fundamental economic case for trade liberalization remains (in terms of efficiency and growth), the political equilibrium has shifted. Going forward, successful liberalization efforts will likely need to explicitly address these concerns – by including robust adjustment assistance for those harmed by trade, by carving out legitimate security exceptions narrowly, and by ensuring trade agreements support sustainable and inclusive growth. The world is learning that liberalization cannot be taken for granted; it must be continually justified and adapted to new realities.
Trade and Tariff Trends in Data (2017–2024)
Hard data on tariffs, trade volumes, and retaliatory measures vividly illustrate the story of the past seven years – one of a pause (and slight backslide) in the long-term liberalization trend, accompanied by volatility in trade flows due to policy shocks.
Global Tariff Levels: After decades of decline, average tariff rates stopped falling and edged up in several major economies post-2017. The clearest case is the United States: Its simple average applied tariff on imports was about 1.7% in 2017, one of the lowest in the world. By 2020, after the tariff waves, that average roughly doubled to ~3.3% . On imports from China specifically, the average U.S. tariff jumped from 3% to over 19% during the trade war . China’s own tariffs on U.S. goods similarly rose from ~8% to ~21% . Other countries also saw slight increases: India’s average tariff climbed to 17% (from ~13% in mid-2010s) due to its budgetary duty hikes . Worldwide, the WTO reported that by 2019, the stock of new import restrictions was at a record high, covering over $1.6 trillion of trade (roughly 7.5% of world imports) implemented since 2017 . This reversed the prior trend where each year saw net tariff reductions. The global trade-weighted average tariff (which accounts for import volumes) likely ticked up modestly in 2018–2019 – IMF estimates suggested global effective tariff levels in 2019 were the highest since 2003 . However, it’s worth noting that many countries did not raise tariffs and some continued to lower them via FTAs (e.g. Japanese and EU tariffs fell due to their EPA; African countries gradually lowered intra-African tariffs under AfCFTA). Thus, the increase in global tariffs was not uniform – it was driven by a few large players. By 2022, the average world tariff remained relatively low (~5-6% by World Bank data) but the era of across-the-board tariff cutting had stalled . Encouragingly, 2021–2023 saw a few tariff reductions: under the Phase One deal, China lowered some retaliatory tariffs and the U.S. reduced one tranche from 15% to 7.5%; the U.S. and EU also mutually suspended tariffs in the Airbus/Boeing dispute . Still, most of the trade-war tariffs stayed in place. In essence, the data shows a plateauing of tariff liberalization, with a slight uptick in protection. This is a stark contrast to the 1990s-2000s when global average tariffs fell steadily. It highlights why experts like Indermit Gill are urging renewed tariff-cutting – to get back on the liberalization track and avoid further escalation .
Trade Volume and Value Changes: The impact of protectionism and other shocks is evident in trade volume growth figures. Global merchandise trade volume grew 4.6% in 2017 (a strong rebound after a trade slump in 2015–16) . But as trade tensions rose, growth slowed to 3.0% in 2018 and then nearly flatlined – WTO data show world trade volume actually declined by –0.1% in 2019 . This was the first contraction in global trade since the 2009 financial crisis, and it coincided with the peak of U.S.-China tariff escalation and associated uncertainty. In value terms, world merchandise exports fell 3% in 2019 (to $18.9 trillion) . WTO analysts explicitly cited trade tensions and slower economic growth as weighing on trade that year . Then came the COVID-19 pandemic, which caused an unprecedented collapse in trade in early 2020. Full-year 2020 merchandise trade volume fell by 5.3% (WTO) – the sharpest one-year drop since World War II . Fortunately, trade rebounded robustly in 2021, growing about 9.7% as economies reopened and stimulus fueled demand . This V-shaped trade recovery demonstrated the resilience of the trading system when markets remain generally open (many COVID-related export restrictions were lifted by late 2020). However, growth moderated again in 2022 to around 3.0–3.5%, and for 2023 the WTO projected only ~1% trade growth . The 2022 slowdown was due to a combination of factors: lingering tariffs, the war in Ukraine (which particularly hit Europe’s trade), high energy prices, and monetary tightening to fight inflation. By 2023, global trade volume had essentially returned to its pre-pandemic trend level but not surged beyond it. In fact, the trade elasticity (trade growth relative to GDP growth) appears to have decreased – trade is growing at around the same pace as world GDP, rather than faster as in the heyday of globalization . The World Bank notes that trade as a share of global GDP has plateaued around 52–53% in recent years, down from the peak of 60% in 2008 . This suggests a trade slowdown partly related to cyclical factors and partly to structural factors like China’s maturing economy and the shift from goods to services (less traded) in output. But protectionism and uncertainty have undoubtedly contributed: IMF research estimated that the U.S.-China trade war alone, at its height, would shave ~0.8 percentage points off global GDP and reduce global trade by over 1% . These data points reinforce how policy choices directly impact trade flows.
Retaliation and Trade Wars by the Numbers: The U.S.-China trade war saw multiple rounds of tariff retaliation, essentially taxing over $450 billion of two-way trade by 2019. By September 2019, the U.S. had imposed tariffs on over $360 billion of Chinese goods (almost all imports from China), and China had retaliated on $110 billion of U.S. goods (covering ~70% of its imports from the U.S.) . The average tariff rates soared as noted. A Peterson Institute analysis in late 2019 calculated that the effective tariff on all Chinese exports to the U.S. was 21% (versus 3% in 2017), and on U.S. exports to China ~20.5% . Beyond China, the U.S. also provoked retaliation from allies: when the U.S. imposed global steel/aluminum tariffs, the EU responded with tariffs on $3.2 billion of U.S. goods (bourbon, Harley-Davidson bikes, etc.), Canada matched $12.6 billion on U.S. steel, aluminum, and consumer goods, and Mexico hit U.S. pork, cheese, and others worth $3 billion . These counter-tariffs were painful enough that the U.S. eventually negotiated quotas or exemptions – by 2021, the U.S. lifted steel tariffs on the EU, UK, and others in exchange for volume restraints, effectively ending that mini trade war . Another front was U.S. threats of auto tariffs (up to 25%) on European and Japanese cars in 2018-19, which prompted intense negotiations. Though the auto tariffs were never implemented (and eventually shelved by 2020), the threat alone chilled investment and forced trading partners to consider concessions . Meanwhile, the EU–U.S. Airbus/Boeing dispute led to mutual tariffs in 2019: the U.S. levied 10% on Airbus planes and 25% on select EU goods (wine, cheese, olives) totaling $7.5 billion, and the EU retaliated in 2020 with tariffs on $4 billion of U.S. exports (including aircraft, ketchup, tractors) . These were suspended in 2021, but only after years of penalizing transatlantic trade. Cumulatively, according to the WTO’s Trade Monitoring, by the end of 2019 approximately 8% of global goods trade was subject to new import restrictions put in place since 2017 – a striking reversal from the early 2010s when each year saw more trade liberalized than restricted. On the other hand, there were also liberalizing measures: the WTO reports that from 2017–2019, G20 members did implement 120 new measures to facilitate trade (e.g. cutting tariffs or simplifying customs) covering about $544 billion of trade . But this was far outweighed by the $1.3 trillion in new restrictive measures in the same period . Retaliation dynamics also played out in smaller disputes – such as India raising tariffs on U.S. goods like almonds and apples in 2019 after the U.S. withdrew India’s duty-free benefits under the GSP program. Turkey in 2018 doubled tariffs on some U.S. imports (cars, alcohol) in retaliation for U.S. steel tariffs and sanctions. Even traditionally open countries like Japan and Korea had a brief tit-for-tat trade spat in 2019, when Japan curbed exports of semiconductor inputs to Korea and Korea retaliated by filing WTO cases and considering ending an intel-sharing pact (a security dispute spilling into trade). These episodes underscore an unfortunate theme: retaliatory trade measures became more common and large economies showed a greater willingness to engage in trade conflicts, something largely avoided in the early 2010s.
Investment and Supply Chains: While not always captured directly in trade data, another trend was the impact on foreign direct investment (FDI) and supply chain reorientation. Global FDI flows fell significantly from 2016 to 2019 (from $2 trillion to under $1 trillion annually), partly due to tax changes but also due to investment uncertainty from trade disputes . Multinational firms delayed or redirected investment. For example, several companies moved some production out of China to Southeast Asia (Vietnam, Thailand, Malaysia) to avoid U.S. tariffs – anecdotally boosting those countries’ trade (Vietnam’s U.S. exports of furniture and electronics jumped, as noted) . Conversely, some U.S. and European companies postponed expansion in China due to concern about tariffs and political pressure. The regionalization of supply chains accelerated: USMCA encouraged North American sourcing for autos; Asian firms built up “China+1” strategies with factories in both China and ASEAN. This means that while global trade growth slowed, intra-regional trade (within Asia, within North America) remained relatively robust as firms adjusted rather than fully reshored. The share of Asian trade occurring within Asia reached ~60%, a record, partly thanks to RCEP and “decoupling” from U.S. markets . So, the data suggests a subtle shift: not outright de-globalization, but a reconfiguration of global trade networks in response to policy. Trade became somewhat more regional and politically aligned.
Overall, the quantitative picture since 2017 shows a clear inflection from past trends. Tariff reductions stalled and, in some cases, reversed. The volume of global trade faltered whenever trade tensions spiked (2019) and only recovered when tensions eased or huge external stimuli intervened. Retaliatory measures and trade-distorting policies proliferated, affecting hundreds of billions in commerce. Yet, despite these headwinds, global trade did not collapse – it adapted. By 2022, world trade reached a record $32 trillion in value (goods and services combined) as per UNCTAD, buoyed by the 2021 rebound . This demonstrates both trade’s resilience and the importance of not letting protectionism spiral further. Moving forward, the data underscores why many economists advocate renewing the push for trade liberalization: to reverse the tariff hikes, restore business confidence, and unleash trade’s contribution to growth. As Gill observed, these trade distortions are policy-made and thus policy-fixable . The statistics provide a roadmap of where action is needed – for instance, unwinding the remaining U.S.-China tariffs (which continue to distort markets), and revitalizing WTO disciplines so that the “record-high” restrictive measures do not become permanent. In essence, the numbers make the case that the global economy has much to gain from reviving liberalization efforts after a period of stagnation.
Conclusion and Outlook
Since 2017, global trade liberalization has experienced both notable setbacks and significant, if uneven, progress through alternative pathways. The eruption of trade wars and protectionist policies marked a departure from the prior era of steadily freer trade. Major economies like the U.S. and India raised barriers, and the multilateral system hit an impasse. At the same time, many countries doubled down on openness via regional agreements (CPTPP, RCEP, AfCFTA, etc.) and unilateral reforms, keeping alive the spirit of liberalization. The result is a divergent landscape: while average tariffs remain historically low by 20th-century standards, they are higher today than a decade ago in several key markets , and trade rules have fragmented with the U.S. and China operating under bilateral tariff ceasefires rather than universally applied WTO rules.
Encouragingly, the tumult of recent years has also driven home the value of open trade. The rapid recovery of trade in 2021 showed that when borders stay open, commerce can adapt and fuel economic rebounds . Businesses have adjusted supply chains but also urged governments to restore predictability. There are signs of an inflection point: The Biden administration has worked quietly to resolve disputes (e.g. lifting steel tariffs on allies, negotiating the Indo-Pacific Economic Framework as a platform for future rules), though it remains cautious on fully removing Trump-era tariffs without reciprocal concessions. The WTO’s 12th Ministerial Conference (June 2022) achieved a few modest wins – an agreement to curb harmful fishery subsidies (the first new WTO pact in years) and a continued moratorium on e-commerce duties – and set in motion discussions on reforming the dispute settlement mechanism by 2024 . If WTO members succeed in reviving a binding dispute system, it would greatly bolster confidence in trade rules. Meanwhile, the momentum of regional liberalization continues: deals like the EU–Mercosur FTA, the Digital Economy Partnership Agreements, and others are in the pipeline. There is also growing recognition that trade policy must be inclusive and sustainable to rebuild public support. Future trade agreements are likely to include stronger labor and environmental standards (as USMCA and EU FTAs now do) and provisions to ensure small businesses benefit, in order to address the criticisms of past globalization. This could form a new “socially conscious liberalization” model.
Geopolitical rivalry remains a wildcard – U.S.–China tensions are structural and could intensify or ease depending on diplomacy. A key question is whether the two giants can find a modus vivendi that allows for competitive coexistence without further decoupling. The Phase One trade truce expires soon; its extension or deepening (or lapse) will significantly shape the tariff environment. Many analysts argue for a managed strategic re-engagement: targeted safeguards for national security tech, but removal of broad tariffs that hurt both economies . If a new understanding is reached, it could unleash suppressed trade and investment flows. If not, the risk is a drifting toward de facto economic Cold War blocs, which would be a markedly less efficient and more unstable trading order.
For the rest of the world, the strategy appears to be hedging and cooperation – hedging against geopolitical risks by diversifying partners, and cooperating through as many trade agreements as possible. The success of RCEP and the expansion of CPTPP demonstrate that large coalitions can move forward without waiting for 100% consensus or U.S. leadership. Africa’s AfCFTA shows a continent taking its development into its own hands through liberalization. These efforts will need continued political will, implementation, and complementary reforms (infrastructure, skills, etc.) to deliver their full benefits . If they succeed, they can lift millions from poverty and cement the case that trade remains a key engine of growth – fulfilling the hopes that Indermit Gill and others have expressed.
In conclusion, the period since 2017 has been a stress test for the global trading system. It revealed cracks – in political support, in institutional frameworks – but it did not break the system. Instead, it catalyzed a patchwork of solutions and a frank rethinking of how to make trade work for more people. The calls for trade liberalization today are more nuanced: they emphasize not just tariff cuts, but also domestic policies to help workers adjust, enforceable standards to ensure fair competition, and cooperation on new issues like digital trade and climate change . The fundamental rationale, however, remains what it has always been: open trade, coupled with the right policies, can increase prosperity for all sides. As this report has detailed, there is abundant evidence – success stories and hard data – that support this view. Avoiding retaliatory trade wars and beggar-thy-neighbor policies is in each nation’s self-interest, especially in an interconnected global economy. The experience since 2017 has been a costly lesson in the dangers of protectionism. The opportunity now is to apply that lesson – to reinvigorate trade liberalization in a way that is politically sustainable and mutually beneficial, steering the world economy toward a more stable and cooperative future.
Summary of Key Takeaways
Retreat and Recalibration: After 2017, the global trend of trade liberalization suffered a setback as major economies turned inward. The U.S.–China trade war alone impacted over $450 billion in trade, driving average U.S. tariffs on Chinese goods above 20% (vs 3% pre-2018) and sparking retaliation by China . This era marked the first notable increase in protectionism since the 1990s, with world trade rules coming under strain.
Regional Liberalization Fills the Void: In response, many countries doubled down on regional and bilateral free trade agreements. Landmark pacts like CPTPP and RCEP were enacted, covering huge markets and cutting tariffs on up to 90% of goods . Africa launched the AfCFTA, aiming to boost intra-continental trade by progressively eliminating most tariffs . These deals signaled continued commitment to open trade despite superpower tensions.
Mixed Outcomes – Successes vs. Setbacks: Case studies reveal divergence: Countries like Vietnam and Japan prospered by embracing liberalization – Vietnam’s exports surged as it joined CPTPP and benefitted from trade diversion during the U.S.–China tariffs . Conversely, India and the United States saw liberalization stall or reverse – India hiked tariffs and quit RCEP talks, missing out on integration , while U.S. protectionism hurt its manufacturers and farmers and undermined the multilateral system . The UK’s Brexit introduced new trade frictions with the EU even as Britain pursued compensatory FTAs. These examples underscore that open trade policies tend to foster growth, whereas protectionism often carries economic costs and setbacks.
Economic & Geopolitical Drivers: Rising inequality, populist politics, and geopolitical rivalry fueled the protectionist turn. Domestic backlash against globalization made trade concessions politically difficult in many nations . Simultaneously, national security concerns (U.S.–China tech tensions, supply chain resilience post-COVID, war-driven sanctions) have increasingly influenced trade decisions. This has led to concepts like “friend-shoring” – trading more with allies – partially supplanting purely market-driven liberalization . Thus, future trade liberalization initiatives must account for security and equity considerations to gain support.
Impact on Trade Flows and Tariffs: By 2019, global trade growth had nearly stalled under the weight of tariffs and uncertainty. World merchandise trade volume fell –0.1% in 2019 (after +2.9% in 2018) , and investment decelerated, reflecting the chilling effect of trade conflicts. WTO monitoring showed G20 trade restrictions hit record highs, covering $747 billion in trade in 2018-19 . The 2020 pandemic caused an even sharper (–5%) trade drop, but also highlighted the importance of keeping supply lines open for critical goods . Trade rebounded in 2021 (+9.7%) as many restrictions were lifted, indicating resilience when liberal trade is restored . Average tariffs globally remain low (~5%), but the progress of reduction has plateaued; in some cases (U.S., India, China) tariffs are higher now than pre-2017 , marking a break in the liberalization trend.
Urgent Calls for Liberalization and Reform: Institutions and experts are urging a return to proactive liberalization to avoid a descent into costly trade wars. Leaders like Indermit Gill emphasize that cutting tariffs and restoring predictability would boost growth and reduce inflationary pressures . The IMF and World Bank estimate that current tariff barriers and uncertainty are shaving significant points off global GDP . The WTO has called for renewed “collective leadership” to rollback restrictive measures and modernize trade rules . Key priorities include reforming the WTO dispute settlement by 2024, negotiating updates on digital trade and services, and ensuring trade initiatives are inclusive (addressing labor and environmental concerns). The broad consensus is that without action, the global trading system could fragment further, but with cooperation, trade can once again be an engine for shared prosperity.
Outlook – Cautious Optimism: The experience since 2017 has been a cautionary tale, but also a catalyst for reimagining trade policy. Many economies have adapted by deepening regional ties, and there is momentum to reinvigorate multilateralism – evidenced by the partial agreements at WTO 2022 and ongoing talks on WTO reform. If the major powers can find compromises (e.g. a U.S.–China tariff détente, agreement on digital and environmental trade norms), and if new trade deals continue to be crafted with wider societal benefits in mind, the world could usher in a renewed era of trade liberalization – one that avoids the mistakes of the past and spreads gains more broadly. The next few years will be pivotal: a chance to solidify the progress made through regional liberalization and to bridge the gaps opened by the trade wars, steering globalization back toward a stable, cooperative path .
