马德里会谈生变，特朗普要求32国对华加税，中方直接反制美国芯片

Group 1 - The recent U.S.-China trade tensions have escalated, particularly highlighted by Trump's call for NATO countries to impose tariffs on China, which he claims supports Russia in the Ukraine conflict [1][2] - Trump's approach of leveraging NATO for economic pressure is unprecedented, as NATO is primarily a military alliance, complicating the situation for European countries that rely on Russian energy [2][6] - The European Union has expressed concerns that sanctions and economic pressure will complicate the resolution of the conflict rather than simplify it [2][6] Group 2 - In response, China has initiated anti-dumping investigations into certain U.S. semiconductor imports, specifically targeting analog chips, which are not as advanced as high-end chips [4][6] - The investigation is based on a significant increase in import volume (37% from 2022 to 2024) and a substantial price drop (52%), indicating potential harm to China's domestic industry [4] - China has also launched a discrimination investigation against U.S. chip exports, claiming that U.S. export controls violate World Trade Organization principles [4][6] Group 3 - The atmosphere of the Madrid talks has shifted due to these developments, with both sides attempting to gain leverage before negotiations [6][8] - Trump's strategy appears to be more about domestic political performance rather than genuine negotiation, as he seeks to rally support by showcasing a tough stance against China [2][6] - The ongoing trade tensions are part of a broader pattern of U.S.-China friction, with potential implications for global trade dynamics and supply chain adjustments [8]
