Trump’s second term as U.S. President lasted less than a hundred days, during which he led the U.S. government to implement a series of intensive tariff measures, with reciprocal tariffs causing significant repercussions in the World Trade Organization and the international community. Trade protectionism, using reciprocal tariffs as a tool, has once again become rampant, sliding into an American-style Trumpism—a blend of populism, unilateralism, hegemonism, and isolationism. It fanatically promotes the notion of U.S. deficit of interest losses, advocating for reducing America’s international obligations and responsibilities, even at the cost of disrupting international order. The U.S. imposing reciprocal tariffs on all trading partners has had a severe impact on the global trade landscape, leading to profound changes in the global economic and trade structure. Firstly,it reshapes the world trade pattern. Relevant countries will accelerate adjustments to their trade with the U.S.strengthen intra-regional trade links, and reconstruct cross-regional trade networks, promoting more diversified supply chain distribution and shifting the focus of global supply chains from cost efficiency to safety first.Secondly, it reshapes the world investment landscape. Under the prolonged influence of U.S. reciprocal tariffs and protectionism, international capital may flow to regions with lower tariff rates and accelerate its return to the U.S.More likely, economies outside the U.S. will cooperate and coordinate with each other, forming new spaces and mechanisms for trade and investment, driving the development of a new model for economic globalization. Thirdly,the tariff rate of 145% imposed by the U.S. on China has reached an unprecedented level. This primarily aims to adjust the global trade landscape, thereby impacting China’s foreign trade and its industrial chain and supply chain layout, potentially bringing complex and far-reaching effects to China’s foreign economic and trade activities as well as its open economy. In response, China should promptly introduce a Chinese Counter-Measure Plan—actively resorting to the dispute settlement mechanism under the WTO framework, working with multiple members to jointly condemn the U.S. for undermining multilateral rules on the WTO platform, promoting WTO reforms without U.S.participation. Secondly, it should deepen regional economic cooperation, building a de-dollarization payment and settlement system, and strengthen internal momentum and industrial resilience through domestic policies.
