美专家：若中国限制稀土出口，美国将承受“毁灭性”后果

Core Viewpoint - The recent threats by Trump to impose an additional 100% tariff on Chinese goods highlight the U.S.'s panic and helplessness regarding its dependence on Chinese rare earth elements, particularly in the context of national security and military capabilities [1][12]. Group 1: U.S. Dependence on Chinese Rare Earths - Approximately 70% of the U.S.'s rare earth supply is imported, with China controlling 90% of the global medium and heavy rare earth refining capacity [4]. - 75% of the U.S. military supply chain relies on Chinese rare earth exports, indicating a critical vulnerability in national defense [4]. - The U.S. military's reliance on Chinese rare earths is evident, as 87% of the supply chain for 153 types of military equipment is dependent on Chinese processing [3]. Group 2: Challenges in Reducing Dependence - The true advantage of China in the rare earth sector lies in its complete industrial chain, from mining to manufacturing, along with decades of accumulated technological patents [5]. - Despite significant investments, Japan has struggled to reduce its dependence on Chinese rare earths, with over 70% still reliant on imports [5]. - Even with the discovery of rare earth resources, Japan faces technological and environmental challenges that hinder commercial extraction [8]. Group 3: Implications for U.S. National Security - The new export controls by China on rare earths directly threaten U.S. military capabilities, potentially leading to a situation where the U.S. military could be severely compromised in a conflict [12][14]. - If the U.S. cannot access the necessary rare earths, its military equipment, including aircraft and missiles, may become inoperable, rendering military spending ineffective [14]. - The ongoing situation underscores the need for the U.S. to acknowledge its vulnerabilities and consider cooperation with China rather than relying solely on tariffs and sanctions [15].
