#美国加征关税 The United States' imposition of additional tariffs is short-sighted 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 retaliation from many countries; from the perspective of the United States itself, while raising tariffs may increase fiscal revenue in the short term, it burdens consumers, weakens the competitiveness of domestic enterprises, and may lead to job losses, ultimately harming the U.S. economy.
