紧接着，4月7日，中国加强了对稀土走私的管控，并在海关查获大量走私的稀土。这一系列举措彻底堵住了美国可能通过走私途径获取稀土的可能。这使得 美国的军事和高科技行业陷入了严重困境，甚至一度让特朗普坐不住了，积极寻求与中国展开谈判。 特朗普近期提出希望访华进行谈判，背后真正的原因似乎并不单纯。表面上看，似乎是中国加强了对稀土的管控，令美国感到压力山大。然而，这一行动是 否真能缓解问题，还是特朗普另有打算，我们不妨从多个角度来分析。 想象一下，掌握了超级大国命脉的关键资源，这种掌控感是何等的强大。稀土，通常被称为"工业维生素"，在现代工业中扮演着至关重要的角色。中国作为 全球稀土的主要供应国，直接影响着世界经济，特别是美国的经济。对于特朗普而言，这场关税战的目标非常明确，他希望通过这种经济手段将中国孤立， 令其处于一个孤立无援的状态。 然而，特朗普或许并未意识到，中国不仅是稀土的最大供应国，实际上，它也手握着美国最急需的稀土资源。4月4日，中国宣布实施稀土出口许可制，这一 消息迅速引起了美国军工行业的紧张情绪。没有稀土，意味着美国将无法生产导弹，而高端战机如F-35也将面临停工的局面。业内人士分析，如果没有足够 的 ...

【文/观察者网 王一】继中国和美国上月就关税问题达成共识后，两国围绕芯片和稀土的对峙愈演愈 烈。在这场双方谁都不想"先眨眼"的拉扯中，美国彭博社6月2日认为，中方似乎越来越占据优势。 报道称，多年来，美国因其对半导体供应链的控制，被认为在争夺技术主导地位的竞争中比中国更具优 势。尽管这届特朗普政府在对华芯片限制上几乎没有放松的迹象，但随着中国加强对关键矿产的管控， 美方发现中方此举会给美国的关键行业带来痛苦，想要摆脱对中国稀土的依赖可能还需要数年时间。 "现阶段，中国的影响力比美国的影响力更经久，"策纬咨询公司（Trivium China）专注于供应链研究的 副总监科里·库姆斯（Cory Combs）表示，美国想要摆脱对中国稀土的依赖还需要十年时间，而中国企 业已经开发出大多数美国芯片的有效替代品，"中国在这场对峙中正在取得进展"。 美国芒廷帕斯稀土矿 视觉中国 作为对美国4月初挑起关税战的反制，中国迅速对钐、钆、铽、镝、镥、钪、钇等7类中重稀土相关物项 实施出口管制措施。之后，双方在瑞士日内瓦就经贸问题达成一系列共识，中方同意采取必要措 施，"暂停或取消自2025年4月2日起针对美国的非关税反制措施"。 但 ...

据和迅网报道，近日国家出口管制工作协调机制办公室组织不同部门，召开打击战略矿产走私出口专项行动会议，引发 国际舆论关注。美国智库最新报告显示，受中国出口管制影响，美国军工企业稀土库存仅剩三个月储备，而全球超九成 稀土加工产能仍牢牢掌握在中国手中。自2023年中国将17种稀土元素纳入出口管制清单以来，战略矿产的非法外流始终 是监管焦点。美国国防部评估报告指出，若中国全面切断稀土出口，其军工生产线将在六个月内瘫痪。 中国海关（资料图） 最近这些年，我国为了自身利益安全，不断对稀土领域进行整合与出口管控， 不仅让美国、欧洲感到了危机，就连印度 与俄罗斯也表达了不满。这不，印度与俄罗斯准备联手搞个动作，妄想在稀土领域打败中国的绝对优势地位。原来，俄 罗斯稀有金属科学院对外宣布，将会与印度科学工业研究理事会达成合作，加强两国在包括稀土在内的战略金属领域的 全面技术合作。两国都是稀土储量大国。但中国拥有稀土加工的关键技术，两国一直没有能力加工出足够的稀土，只能 够大量从我国进口。 5月初，俄联邦稀有金属科研院和印度科学工业研究理事会火速签了合作协议，说要搞稀土深加工技术攻关。明面上喊 着"确保工业自主"，暗地里瞄着西方市 ...

Core Viewpoint - The ongoing trade war initiated by the U.S. under Trump's administration is significantly impacting the development of the sixth-generation fighter jet, particularly due to the reliance on rare earth materials supplied predominantly by China [1][9][12]. Group 1: Impact on Military Development - The U.S. military's sixth-generation fighter jet project, specifically the F-47, is heavily dependent on rare earth elements such as neodymium, praseodymium, dysprosium, and terbium, which are crucial for high-performance magnets and radar systems [7][12]. - The recent approval for Boeing to produce the F-47 occurred just before China announced new export controls on rare earth materials, creating uncertainty for the U.S. military's development plans [9][12]. - The lack of sufficient rare earth supply could lead to significant delays or even halts in the production of critical military components, affecting the overall military readiness of the U.S. [7][12][18]. Group 2: China's Export Control Measures - China's new export control measures restrict seven categories of medium and heavy rare earth elements, which are vital for military, aerospace, and high-tech applications [12][26]. - The majority of medium and heavy rare earth supplies come from China, which possesses the largest reserves globally, creating a strong supply chain that the U.S. heavily relies on [12][19]. - The implementation of these controls has led to a near halt in rare earth exports from China, with U.S. companies facing potential inventory shortages and uncertainty in securing new supplies [26][28]. Group 3: Strategic Implications and Alternatives - The strategic significance of rare earth elements is underscored by their essential role in various industries, including military, aerospace, and high-tech sectors, where their absence could severely hinder production capabilities [12][16]. - While the U.S. may consider sourcing rare earth materials from other countries, challenges such as the lack of processing technology and infrastructure in those nations limit the feasibility of such alternatives [19][20]. - The U.S. government is exploring deep-sea mining as a potential solution to the rare earth supply crisis, but this approach faces significant technological and environmental hurdles, making it a long-term and uncertain solution [24][28].
