美国被打疼，特朗普威胁对华征100%关税，不到半天，特朗普服软了

Core Viewpoint - China's recent export controls on critical materials, including rare earths and lithium batteries, have significantly impacted the U.S. and are seen as a strategic move to accelerate decoupling from the U.S. amid ongoing tensions [1][3]. Group 1: China's Export Controls - China announced export controls on key materials, which has caused a strong reaction from the U.S., particularly from former President Trump, who expressed outrage and threatened to impose 100% tariffs on China [1]. - The decision to implement these controls is rooted in China's realization that the U.S. has no intention of making substantial concessions in trade negotiations, leading to a strategic shift towards decoupling [3]. Group 2: U.S. Response - Trump's initial anger was followed by a willingness to negotiate, indicating that the U.S. is not prepared for an all-out trade war despite the tensions [5][7]. - U.S. Trade Representative Jamison Greer stated that while the U.S. is ready for a trade war if necessary, the current focus remains on negotiations to ease tensions [7]. Group 3: Implications for Industries - The export controls are perceived as an economic "nuclear war" aimed at undermining U.S. high-end manufacturing, particularly in the AI sector, highlighting the interdependence of U.S. technology and Chinese resources [5]. - The U.S. high-tech industry, including semiconductor production, relies heavily on Chinese rare earth materials, suggesting that the U.S. may face significant challenges if supply chains are disrupted [3].
