#美国加征关税 The United States' imposition of tariffs is shortsighted and detrimental to both others and itself. From an international perspective, this move undermines global trade rules, disrupts stable industrial and supply chains, hinders economic globalization, and provokes dissatisfaction and countermeasures from numerous countries; from the perspective of the United States itself, although raising tariffs may increase fiscal revenue in the short term, it imposes a heavier burden on consumers, weakens the competitiveness of domestic enterprises, and may lead to job losses, ultimately backfiring on the U.S. economy.
