美称稀土将多如牛毛？美澳85亿合作藏深坑，570万吨仅中国零头？

Core Viewpoint - The recent $8.5 billion mineral cooperation agreement between the U.S. and Australia highlights the urgency for the U.S. to reduce its dependence on Chinese rare earth resources, particularly in the context of military applications [1][10]. Group 1: U.S. Concerns and Military Dependency - The U.S. military relies heavily on rare earth elements, with 87% of its 153 major weapon systems dependent on Chinese processing [1]. - The F-47 fighter jet requires 8 to 12 kilograms of rare earths, and 70% of the heavy rare earths used in the U.S. come from China, indicating a significant vulnerability in the U.S. defense supply chain [1]. Group 2: Australia's Position and Resources - Australia ranks fourth globally in rare earth reserves, with 5.7 million tons, and possesses the only large-scale heavy rare earth production base outside of China, making it a strategic partner for the U.S. [6]. - The agreement is seen as mutually beneficial, with Australia aiming to enhance its position in the global mineral market while providing the U.S. with critical resources [6]. Group 3: Challenges and Realities - Despite the cooperation, Australia's rare earth reserves are significantly lower than China's, which holds 44 million tons, over seven times more than Australia [7]. - The timeline for Australia to scale up production to meet U.S. needs is unrealistic, with full-scale production not expected until 2028, while the U.S. seeks self-sufficiency within a year [7][10]. - The technological and industrial barriers that China has established over years cannot be easily overcome by mere agreements or investments, as China controls 90% of the global rare earth supply chain and extraction technology [7][8]. Group 4: Conclusion on the Agreement's Impact - The $8.5 billion agreement appears to be more of a political gesture to alleviate U.S. anxiety over rare earth dependence rather than a practical solution to the underlying supply chain issues [10]. - The global supply chain dynamics are complex and cannot be altered solely through political maneuvers; achieving true independence in rare earth supply will require substantial technological advancements and production capabilities [10].
