US–China Trade War

The Trump administration imposed tariffs on $50 billion of Chinese goods, citing unfair trade practices and intellectual property violations; China retaliated with equivalent tariffs, escalating into a $360-billion tariff standoff that disrupted global supply chains and accelerated decoupling pressures.

Origins

The Trump administration's trade offensive against China cited three main grievances: a bilateral trade deficit of over $375 billion; alleged Chinese practices of forced technology transfer, intellectual property theft, and subsidies for state-owned enterprises; and China's alleged manipulation of the renminbi. In March 2018, President Trump signed an executive order imposing 25% tariffs on $50 billion of Chinese goods under Section 301 of the Trade Act of 1974. China immediately retaliated with equivalent tariffs on US goods.

Escalation

The tariff war escalated through 2018–2019 in successive rounds. By September 2019, the US had imposed tariffs on approximately $360 billion of Chinese goods; China had tariffed roughly $110 billion of US exports (constrained by the smaller volume of US imports). Additional pressure included restrictions on Huawei and ZTE, export controls on semiconductors, and the effective blacklisting of Chinese technology companies. A "phase one" trade deal was signed in January 2020, but core structural issues remained unresolved.

Long-Term Consequences

The trade war accelerated a broader decoupling of the US and Chinese economies in technology, investment, and supply chains. Companies began diversifying manufacturing out of China to Vietnam, Mexico, and India. The concept of "friend-shoring" — concentrating supply chains in allied countries — gained traction. The Biden administration largely maintained Trump-era tariffs while adding new technology restrictions. The trade war was widely seen as marking the end of the post-Cold War consensus that economic engagement with China would lead to political liberalisation.

Narrative Comparison

SourceNarrative
PRC Official NarrativeThe Chinese government firmly opposed U.S. unilateralism and trade protectionism, characterising the trade war as a violation of WTO rules that damaged the interests of both countries and the global multilateral trading system. China maintained that its development achievements were the result of the Chinese people's own hard work and self-reliance, not the product of alleged unfair trade practices. While firmly defending its legitimate rights, China consistently showed restraint, repeatedly expressing willingness to resolve differences through negotiation and seeking consensus through WTO dispute settlement mechanisms and bilateral dialogue. The U.S. bore responsibility for initiating the trade war, and China's countermeasures were a legitimate response to unilateral U.S. actions — cooperation benefits both sides while confrontation harms both.
U.S. Official PositionThe Trump administration characterised the trade war as a necessary correction to decades of unfair Chinese trade practices, arguing that previous engagement and dialogue policies had fundamentally failed to change China's trade behaviour. The USTR Section 301 investigation concluded that China's state-directed technology acquisition strategy had caused substantial harm to U.S. companies, and that forced technology transfer and intellectual property violations were systemic state-level practices. The administration regarded unilateral tariffs as the necessary instrument to compel China to open its markets, reform state enterprise subsidy systems, and cease forced technology transfer. While the Phase One deal represented a short-term achievement, the administration held that structural reform goals remained unmet; the tough posture toward China was continued and deepened under the Biden administration.
Western Academic AssessmentEconomists and policy scholars are significantly divided in their assessments of the trade war. Some acknowledge the legitimacy of U.S. concerns about China's structural trade practices but criticise unilateral tariffs as an inefficient instrument that imposes additional costs on domestic firms and consumers. Klein and Pettis (2020) argue that the deep root of the US-China trade imbalance lies in structural differences in each country's domestic savings and consumption patterns, rather than trade policy distortions alone, making tariffs an inadequate tool for resolving structural imbalances. Most scholars view the trade war as having accelerated US-China "strategic decoupling," marking the substantive collapse of the post-Cold War engagement-based policy consensus toward China, and signalling deep challenges to the rules-based multilateral trading system.

Key Milestones

  1. Trump signs memorandum announcing tariffs on $50 billion of Chinese goods

    President Trump signed a presidential memorandum under Section 301 of the Trade Act of 1974, directing the USTR to prepare a tariff list targeting approximately $50 billion of Chinese goods, citing alleged practices of forced technology transfer and intellectual property violations. The action marked the formal start of the trade war.

  2. First tranche of $34 billion tariffs takes effect; China retaliates in kind

    The United States formally imposed 25% tariffs on a first tranche of approximately $34 billion of Chinese goods, covering industrial machinery, aerospace components, and other products. China retaliated the same day with equivalent tariffs on U.S. soybeans, automobiles, and seafood, marking the start of active tariff confrontation.

  3. US and China sign Phase One trade deal

    The US and China signed the Phase One economic and trade agreement in Washington. China committed to purchasing approximately $200 billion in additional U.S. goods over two years, while the US agreed to suspend planned tariffs and reduce some existing rates. The deal did not address structural reform issues, leaving the fundamental disputes unresolved.
