On April 10, 2017, U.S. President Trump announced a 90-day suspension of new tariffs for over 75 countries that had not taken retaliatory measures, and the existing tariff rates would be uniformly reduced to 10%. However, China was excluded, and tariffs on China were instead increased to 125%. This policy aimed to provide U.S. businesses with time to adjust their supply chains while pressuring China to make concessions in trade negotiations. The market reacted strongly, with U.S. stocks rebounding significantly, and the Nasdaq index rose by 12% in a single day. However, this policy exacerbated trade frictions between China and the U.S. and could potentially drive up U.S. inflation, affecting global economic stability.
