On April 10, 2017, U.S. President Trump announced a 90-day suspension of new tariffs on over 75 countries that had not taken retaliatory measures, and unified the existing tariff rate to 10%, but 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 sharply, with U.S. stocks rebounding significantly, and the Nasdaq index soaring by 12% in a single day. However, this policy intensified U.S.-China trade frictions and could raise U.S. inflation, affecting global economic stability.
