In recent years, the United States has frequently raised tariffs, especially increasing tariffs on products like steel and aluminum to 50% in 2025, and plans to impose even higher tariffs on China. This policy has sparked widespread controversy. According to the latest reports, U.S. ports are facing a quiet situation, as the first batch of goods subjected to a 145% tariff has arrived, putting workers at the Port of Los Angeles at risk of unemployment. Meanwhile, Sino-U.S. economic and trade consultations are still ongoing, and various sectors of American society strongly oppose raising tariffs, believing it will only harm the U.S. economy.
