#美国加征关税

In recent years, the United States has implemented trade protectionist policies through increased tariffs, primarily targeting trade partners such as China and the European Union, affecting sectors like steel, aluminum products, and electronics. Starting in 2018, the United States imposed multiple rounds of tariffs on goods imported from China, citing the reduction of the trade deficit with China and the protection of national security, with tariff rates reaching as high as 25%. This action prompted retaliatory measures from China and triggered disruptions in the global supply chain. The World Trade Organization has repeatedly warned that unilateral tariffs violate multilateral trade rules and exacerbate global economic uncertainty. High tariffs increase business costs, putting pressure on consumers with rising prices, and forcing some industries to shift production capacity. In the long term, while trade barriers may provide short-term protection for specific sectors, they harm the efficiency of international division of labor and hinder global economic growth.
