The Multiple Logics Behind the U.S.–China Section 301 Tariffs: A Cross-Disciplinary Analysis of International, Political, and Economic Factors

Abstract

The U.S.-China trade conflict flared up again on May 14, 2024, when the U.S. finally decided to restore Section 301 tariffs on Chinese goods, four years after the Trump administration ended its review of China’s policies. This paper uses methods from international relations, economics, and the political economy to explain how strategic, domestic, and economic factors shaped the design and implementation of the tariffs. High tariffs were levied on Chinese exports of strategic significance, mainly extending to electric vehicles, semiconductors, and clean energy products. Phased implementation and exclusion policies mitigated their economic impact and potential inflationary effects within the U.S. Overall, the levying of high tariffs was a strategically motivated response aimed at national security. At the same time, the implementation was economically prudent because it allowed for alternative supply sources and limited pass-through costs. The tariffs enjoyed political support among specific industries and labor groups ahead of an election year and was backed by related programs such as CHIPS and the Inflation Reduction Act. Internationally, coordination with allies and the weakened enforcement of rules by the World Trade Organization also provided a favorable environment for unilateral action. In summary, this paper provides an integrated explanation for the tariff escalation in 2024 and suggests testable hypotheses for further research on price pass-through, trade diversion, and welfare effects.
