刚定下访华日程，24小时不到，特朗普王牌被废，中方发现了美国弱点

Core Viewpoint - The article discusses the implications of a recent Supreme Court ruling that invalidated President Trump's use of the International Emergency Economic Powers Act to impose global tariffs, significantly impacting U.S.-China trade relations and Trump's negotiating power [1][3]. Group 1: U.S. Tariff Policy - The Supreme Court ruled that Trump's global tariff measures were unconstitutional, leading to the immediate cessation of these tariffs, which had generated over $160 billion in revenue [1][3]. - Following the ruling, Trump attempted to implement a new tariff policy under the Trade Act of 1974, imposing a 15% tariff on global imports, but this approach has significant limitations and requires Congressional approval for extension [3][5]. Group 2: U.S.-China Relations - The U.S. government's inability to maintain unilateral tariff measures exposes weaknesses in its internal power structure, limiting Trump's ability to exert pressure on China [5][7]. - The upcoming visit to China is driven by urgent U.S. economic needs, including agricultural exports and maintaining confidence in U.S. debt, indicating a shift towards a more cooperative dialogue with China [5][7]. Group 3: Global Trade Dynamics - The failure of unilateral tariff policies highlights the importance of mutual respect and equal negotiation in international trade, suggesting that reliance on power dynamics is ineffective [7]. - The internal turmoil within the U.S. government serves as a reminder of the fragility of global trade order and the need for stable governance and a strong economy to support international standing [7].
