自作自受！美国自废优势想卡中国，却被一招反制，军工产业被牵连

Core Insights - The article discusses the strategic importance of rare earth elements (REEs) in the context of U.S.-China technological competition, highlighting how China uses rare earth controls as a countermeasure against U.S. chip restrictions [1][8]. Summary by Sections Understanding Rare Earth Elements - Rare earth elements are a group of 17 metallic elements essential for modern industrial applications, often referred to as "industrial vitamins" [3]. - They are categorized into light rare earths, used in emerging technologies like electric vehicle batteries, and heavy rare earths, critical for military applications such as radar and stealth technology [5][6]. China's Rare Earth Industry - China has become a dominant player in the global rare earth market, producing 97.54% of the world's rare earths by the early 1990s, largely due to advancements in extraction and purification techniques [17]. - The country has consolidated its rare earth production under six major groups to manage over 95% of its capacity, moving away from a fragmented and low-cost production model [12][15]. U.S. Dependence and Challenges - The U.S. once controlled 79% of global rare earth production but outsourced much of the processing to China due to environmental and cost concerns [7][10]. - Current U.S. efforts to revive its domestic rare earth industry face significant challenges, including technological barriers, higher labor costs, and the need for substantial investment and time [19][23]. Strategic Implications - China's rare earth export controls are designed to limit U.S. technological advancement by requiring global companies to register with the Chinese government if they use Chinese rare earths in their products [24]. - The article emphasizes that China's rare earth capabilities not only serve as a response to Western challenges but also mark its transition from a resource-rich nation to a manufacturing powerhouse [28].
