为应对中国稀土管制，特朗普盯上太平洋海底

Core Viewpoint - The Trump administration is drafting an executive order to allow the U.S. to stockpile metal resources from the Pacific seabed in response to China's dominance in the battery metals and rare earth supply chain, but faces significant challenges [1][3]. Group 1: Challenges of Deep-Sea Mining - There is widespread domestic opposition in the U.S. to deep-sea mining due to environmental concerns, with experts warning that it could cause far greater damage than land mining [5]. - The U.S. lacks the necessary technology and capabilities for deep-sea mining, which involves high costs and complex operations, making it potentially more expensive than importing rare earth materials [5]. - The U.S. faces pressure from the United Nations, as the International Seabed Authority (ISA) has stated that all exploration and mining activities must be regulated by them, and unilateral actions could violate international law [7]. Group 2: Context of Rare Earth Supply Chain - The U.S. is currently highly dependent on China for both raw materials and development technology related to rare earth elements, which poses a risk if China decides to restrict exports [3]. - China has already begun implementing export controls on seven rare earth items in response to U.S. tariffs, highlighting the ongoing tensions in the trade relationship [3].
