挑战政府贸易政策，削弱白宫对外筹码，美法院叫停特朗普“关税战”

Core Viewpoint - The U.S. International Trade Court ruled that the Trump administration's tariff policies are illegal, stating that federal law does not grant the president "unlimited power" to impose tariffs on imports from nearly all countries [1][3][4]. Group 1: Legal and Political Implications - The court's decision prohibits the Trump administration from executing tariffs imposed under the International Emergency Economic Powers Act, asserting that the president cannot impose comprehensive tariffs based on "trade imbalance" [3][4]. - The ruling is seen as a significant legal challenge to the current administration's tariff strategy, which is described as having collapsed due to its own missteps [1][4]. - The White House criticized the ruling, claiming that trade deficits constitute a "national emergency" and that the resolution of such emergencies should not be determined by unelected judges [4][6]. Group 2: Economic Impact - The ruling may lead to a slowdown in the U.S. government's ability to impose tariffs, requiring more time-consuming trade investigations and reliance on other trade laws [1][4]. - The decision is viewed as a victory for states and businesses adversely affected by the tariffs, which have been described as a significant tax increase on American families and businesses [6][5]. - Following the court's ruling, financial markets reacted positively, with the U.S. dollar rising and Asian stock markets experiencing gains, indicating a potential easing of trade tensions [5][6]. Group 3: International Reactions - The ruling could weaken the U.S. government's efforts to negotiate new trade agreements globally, as it undermines the use of unilateral tariffs as leverage in negotiations [8][9]. - The European Union and Australia are considering the implications of the ruling, with calls for the U.S. to eliminate tariffs deemed unreasonable [8][9]. - Japan is also closely monitoring the situation, preparing for ongoing trade negotiations with the U.S. [8][9].
