美国法院判定对等关税非法，特朗普遭釜底抽薪，还好中国没有妥协

Group 1 - The core viewpoint of the articles revolves around the unexpected judicial ruling against President Trump's tariff policies, which has significant implications for U.S. trade strategy and international relations [1][4][5] - The U.S. Court of Appeals overturned several of Trump's historic tariff policies, raising questions about the legality of his authority to impose such tariffs under the economic emergency powers granted by Congress [1][4] - Trump's response to the ruling was assertive, maintaining that all tariffs remain in effect and emphasizing the necessity of these tariffs for national strength and fiscal stability [1][2] Group 2 - The White House defended Trump's actions, asserting that he is exercising powers granted by Congress, and emphasized that the court's ruling does not undermine congressional authority or the rule of law in the U.S. economy [2][4] - The court's decision primarily focused on the legitimacy of Trump's power source rather than directly declaring the tariffs illegal, thus clarifying the boundaries of executive authority [4] - From China's perspective, this situation poses significant challenges for Trump, as a potential failure in his appeal could mark a constitutional setback for his presidency, while China continues to adapt its trade and industrial strategies in response to U.S. tariffs [5][7]
