中美关税战暂缓，稀有金属管制为什么不放开？

Core Viewpoint - The ongoing trade negotiations between China and the U.S. reveal a complex interplay of tariffs and resource control, particularly concerning rare metals, which are critical for modern industries and military applications [1][3][5]. Group 1: Tariff and Trade Dynamics - The U.S. has canceled 91% of tariffs on Chinese imports, but retains a 10% "base tariff" on key sectors like semiconductors, indicating a strategic approach to maintain leverage in technology [3]. - China's rare earth exports have significantly decreased, with a 37% year-on-year drop in the first four months of 2025, and exports of tungsten to the U.S. have reached zero [3][5]. - The trade negotiations are not merely about tariffs but represent a broader "resource war," where control over rare metals is seen as crucial for technological and military supremacy [3][5]. Group 2: Strategic Importance of Rare Metals - Rare metals such as tungsten, tellurium, and indium are essential for various high-tech applications, including military hardware and renewable energy technologies [5][9]. - China holds a dominant position in the global supply of these metals, with 72% of tungsten, 83% of rare earths, and 95% of indium reserves, giving it significant leverage in negotiations [5][9]. - The strategic value of these metals is underscored by their critical roles in advanced military systems, such as the guidance systems of intercontinental missiles and components of fighter jets [5][9]. Group 3: Future Resource Strategies - China is implementing a comprehensive strategy to secure its resource supply chain, including establishing strategic reserves and controlling the entire production process from mining to processing [9]. - The country is actively investing in overseas mining operations to ensure a steady supply of critical materials, which could further enhance its bargaining power in future negotiations [9]. - The ongoing developments suggest that while tariffs may be paused, the underlying competition for resource control will continue to intensify, impacting global supply chains and geopolitical dynamics [1][9].
