访华刚定下，不到24小时，美王牌被废，英媒：中国发现了美国弱点

Core Viewpoint - The U.S. Supreme Court ruled that Trump's $160 billion tariffs were illegal, undermining his leverage ahead of his visit to China, and highlighting the limitations of U.S. trade policy under the International Emergency Economic Powers Act (IEEPA) [2][4][6]. Group 1: Legal and Economic Implications - The Supreme Court's ruling stated that the tariffs imposed under IEEPA exceeded legal authority and must be immediately stopped and abolished [4][6]. - The tariffs collected under IEEPA amounted to approximately $1,335 billion by December last year, increasing to about $1,600 billion by February 20 this year [6][8]. - The ruling raises questions about potential refunds and interest payments to affected parties, complicating the U.S. government's financial position [8][10]. Group 2: Impact on U.S.-China Relations - Trump's reliance on tariffs as a negotiation tool has been significantly weakened, as the legal basis for such actions has been challenged [10][12]. - The new trade measures Trump signed before his visit are limited to a maximum tax rate of 15% and can only last for 150 days without Congressional approval, indicating a shift in strategy [10][12]. - Chinese companies view the U.S. market as a stable revenue source, with many American firms operating in China showing no plans to withdraw, contrary to the administration's aggressive stance [12][14]. Group 3: Domestic Political Dynamics - The ruling reflects the internal conflicts within the U.S. political system, where even Trump's appointees in the Supreme Court can challenge his policies [14][16]. - The agricultural sector is particularly sensitive to trade relations with China, as reduced orders can directly impact U.S. farmers and create political pressure on Washington [16][18]. - The U.S. debt and trade deficit situation complicates negotiations, as any changes in Chinese investment behavior could lead to significant market volatility [16][18]. Group 4: Future Negotiation Landscape - China has made it clear that it expects the U.S. to remove all unreasonable tariffs to restore normal trade relations, emphasizing the need for mutual respect in negotiations [20][22]. - The changing global environment, with European nations focusing on economic cooperation rather than confrontation, diminishes the effectiveness of U.S. pressure tactics [22][24]. - The Taiwan issue remains a critical point, with China asserting that it cannot be used as a bargaining chip, which could jeopardize the significance of Trump's visit if not handled carefully [24][26].
