Trump imposed tariffs on several countries to protect American industries, notably 34% on China, 20% on the European Union, and 10% on Britain and Brazil, while it reached 49% on Cambodia. Despite his new trade agreement with China, the U.S. Department of Commerce confirmed that tariffs on China would not change and remain at 55%. These policies have affected global trade, as Britain's exports to America recorded their largest decline due to these tariffs. In another development, a federal court ruled some of the tariffs imposed by Trump to be invalid, which could lead to changes in U.S. trade policy and impacts on the global economy.
