特朗普又吹牛，美国稀土将多如牛毛？

Core Viewpoint - The article discusses the unrealistic expectations surrounding the U.S. reliance on Australia for rare earth minerals, emphasizing that despite Australia's claims, it cannot quickly replace China's dominance in the rare earth supply chain [1][10]. Group 1: U.S.-Australia Cooperation - The U.S. signed an $8.5 billion agreement with Australia for critical minerals and rare earth cooperation, driven by the need to reduce dependence on China [3]. - Australia claims it can meet a significant portion of the U.S. demand for critical minerals, including rare earths, but the reality of its capabilities is questioned [4]. Group 2: Australia's Rare Earth Capabilities - Australia has the fourth-largest rare earth reserves globally, with 5.7 million tons, but this is only 1/8 of China's 44 million tons [4]. - The largest and highest-grade rare earth mine in Australia will not reach large-scale production until 2028, making it impossible for the U.S. to quickly increase its rare earth supply [4][6]. Group 3: China's Dominance in Rare Earths - China controls 70% of the global rare earth production and 90% of the refining capacity, making it difficult for the U.S. and Australia to compete without the necessary processing technology [6]. - The development of rare earth refining technology requires significant time and investment, with estimates suggesting it would take at least five to six years for the U.S. and Australia to catch up to China's current capabilities [6][10]. Group 4: Military Implications - A significant portion of the U.S. military's supply chain relies on Chinese rare earths, with 87% of the supply chain for 153 types of military equipment passing through China [8]. - The U.S. military's reliance on rare earths is critical for maintaining its technological edge and operational capabilities [7]. Group 5: Historical Context - Previous attempts by the U.S. to achieve rare earth independence, such as during the Obama administration, have resulted in minimal success, highlighting the challenges of developing a domestic rare earth industry without mature technology [11].
