局势已变，特朗普已经没有办法嘚瑟了，中方直接通告美国！

Group 1 - The U.S. Supreme Court ruled against Trump's unilateral tariff policy, declaring it illegal and limiting presidential power over tariffs, which significantly undermines Trump's core policy tool [3][12] - Trump's initial response to the ruling was to issue a new executive order to impose tariffs under a different legal framework, but this move lacks the previous deterrent effect and faces legal challenges [5][12] - The changing dynamics in U.S.-China relations are evident as Trump maintains some tariffs while signaling a willingness to negotiate, reflecting a strategic balance between hardline and conciliatory approaches [8][14] Group 2 - China's response to the evolving trade situation emphasizes a commitment to rationality and core interests, outlining four key principles for U.S.-China relations, including adherence to the one-China principle and opposition to unilateral sanctions [10][12] - The ongoing trade conflict is characterized as a struggle between unilateralism and multilateral rules, with the Supreme Court's decision marking a shift away from the notion of presidential dominance in trade policy [12][14] - The current situation serves as a reminder that no country can benefit long-term from bullying tactics, highlighting the importance of equal dialogue and cooperative approaches in global trade [14]
