中美打响没有硝烟的战争，特朗普放下豪言，两年废掉中国一张王牌

Core Viewpoint - The article argues that the United States' goal to eliminate dependence on Chinese rare earth metals within two years is unrealistic due to the complexities involved in rare earth extraction and processing [1][2][4]. Group 1: Challenges in Rare Earth Extraction - Extracting rare earth elements is a complex process that requires significant electrical power, which the U.S. lacks compared to China [1]. - The construction of necessary infrastructure for mining and transporting rare earth materials is a time-consuming endeavor [1]. - The separation and purification of rare earths generate hazardous waste, requiring advanced environmental technology that the U.S. currently does not possess [1]. Group 2: Economic Viability and Investment - The Western capital markets prioritize profitability, and without sufficient returns, there is little incentive to invest in the rare earth industry [2]. - Government subsidies would be necessary for the U.S. to develop a competitive rare earth sector against China's low-cost production [2]. Group 3: Political Implications - Trump's announcement serves more as a political maneuver to project a strong leadership image rather than a feasible economic strategy [4]. - The statement aims to simplify complex industrial challenges into a patriotic rallying cry, appealing to domestic audiences while signaling resolve to international allies and adversaries [4]. Group 4: Conclusion on U.S.-China Rare Earth Competition - The article concludes that despite political rhetoric, the U.S. is unlikely to overcome the economic realities and competitive advantages that China holds in the rare earth sector [6].
