Core Viewpoint - The recent $8.5 billion rare earth cooperation agreement between the U.S. and Australia highlights the U.S.'s overconfidence in overcoming its reliance on China, despite lacking the necessary refining technology to utilize the raw materials effectively [1][3]. Group 1: U.S.-Australia Cooperation - The U.S. and Australia plan to invest $1 billion each to support critical mineral projects, but Australia's lithium exports still heavily depend on China, indicating a significant gap in processing capabilities [5]. - The agreement mentions "processing capacity," yet the planned gallium refining plant in Western Australia will only have an annual capacity of 100 tons, which is insufficient to meet demand [3]. Group 2: China's Dominance in Rare Earths - Over 90% of global rare earth refining capacity is concentrated in China, which leads in green smelting and high-purity refining technologies [3]. - The U.S. military's requirements for high-purity rare earths cannot be met domestically, as the highest purity achieved is only 99.1% to 99.9%, comparable to China's technology from the 1990s [3]. Group 3: Technological Barriers - The key issue in the rare earth competition is not merely access to raw materials but the ability to refine them effectively, which China currently dominates [7]. - The U.S. may acquire raw materials, but without Chinese technological support, establishing a competent refining system will be challenging [5][7]. - Previous setbacks, such as MP Materials facing business stagnation due to export restrictions to China, illustrate the difficulties within the U.S. supply chain [5].
