Core Viewpoint - The article discusses China's strict export controls on rare earth elements, which are crucial for the semiconductor and military industries, highlighting the strategic implications for global supply chains and the competitive landscape between China and the U.S. [2][4][17] Semiconductor Industry - The semiconductor industry is heavily reliant on rare earth elements, with every item on the control list corresponding to critical processes, achieving 100% coverage [6][12]. - Key applications include chemical mechanical polishing (CMP) using high-purity cerium oxide, essential for achieving atomic-level flatness in wafers, with significant implications for chip yield [12][6]. - The EUV lithography machines, vital for advanced chip manufacturing, depend entirely on controlled rare earth materials, with no substitutes available [9][10]. Military Applications - Rare earth elements are termed "war metals" in defense, with 87% of U.S. weapon systems relying on these materials, which lack mature alternatives [17][18]. - The F-35 fighter jet requires 417 kg of rare earth materials, with critical components sourced from China, indicating a significant vulnerability in U.S. military capabilities [19][22]. - The Virginia-class submarines and missile systems also depend on rare earth materials for performance and reliability, underscoring the strategic importance of these resources [24][27]. Domestic Rare Earth Industry - China's rare earth industry is characterized by a complete ecosystem from mining to application, with six major groups controlling over 90% of resources and refining capacity [32][31]. - The industry has seen significant consolidation, enhancing resource utilization and technological collaboration, which supports the effective implementation of export controls [35][34]. Strategic Value of Export Controls - The export controls are not merely supply restrictions but represent a strategic shift from resource-based to value-driven industry leadership, reshaping global supply dynamics [37][36]. - The controls have led to a significant increase in prices and profit margins for domestic rare earth companies, breaking the previous low-price export model [38][39]. Impact on the U.S. - The U.S. faces a critical dependency on China for rare earth imports, with 77% of its supply coming from China, leading to severe supply chain vulnerabilities [43][41]. - Efforts to establish a domestic supply chain for rare earths are hindered by high costs, lengthy approval processes, and technological barriers, making it difficult to replace Chinese sources [44][45]. - The military and semiconductor sectors are experiencing significant operational impacts due to supply shortages, with production capabilities being curtailed [45][41]. Geopolitical Implications - The article emphasizes the ongoing geopolitical struggle over resource sovereignty and technological dominance, with China leveraging its rare earth resources to enhance its strategic position globally [46][48]. - The current situation illustrates that technological advancement alone does not equate to industrial control, as resource advantages combined with regulatory frameworks create a more resilient strategic force [48][47].
