稀土牌双线打法威力有多大？特朗普急于访华，美企已停工关厂了！

Core Viewpoint - The ongoing supply chain battle between China and the U.S. is intensifying, with the U.S. employing export controls as a central issue in trade negotiations, while China retaliates by controlling rare earth supplies [1][3]. Group 1: Supply Chain Dynamics - The U.S. has implemented stringent measures in the chip sector, effectively isolating China, while China has responded by leveraging its control over rare earth resources [1][6]. - China has adopted a "dual-line" strategy in rare earth exports, tightening controls on critical materials while easing restrictions on ordinary rare earths to meet civilian demand [6][4]. Group 2: Export Control Measures - Since April 2023, China has introduced an export licensing system for seven critical minerals, leading to a complete halt in exports of certain rare earths like terbium and dysprosium, which were previously exported in significant quantities [3][4]. - The U.S. has felt the pressure from these export restrictions, with companies like Ford experiencing production halts due to a lack of rare earth magnets essential for manufacturing [4][6]. Group 3: International Reactions - The G7 countries are collaborating on a "critical minerals action plan" to counter China's rare earth strategy, with the U.S. pushing for resource development in regions like Greenland and Canada [6][7]. - Despite these efforts, China maintains a dominant position, controlling 80% to 90% of the global rare earth supply, making it challenging for the U.S. and its allies to reduce dependency [6][7]. Group 4: Future Implications - The control of rare earth resources is pivotal in the trade war, with potential significant impacts on U.S. high-tech industries if China escalates export restrictions [7]. - The effectiveness of any agreements between the two nations will depend on the U.S.'s genuine commitment to reducing trade friction, as past behaviors have led to skepticism from China [7].
