美国买通“内鬼”，四个月走私四千吨稀土，中国决定动真格的

Core Viewpoint - The article highlights a significant increase in the import of antimony oxide by the United States from Thailand and Mexico, which raises concerns about a potential smuggling network involving Chinese enterprises [1][7]. Group 1: Smuggling Operations - Between December 2024 and April 2025, the U.S. imported 3,834 tons of antimony oxide from Thailand and Mexico, surpassing the total of the previous three years [1][7]. - The smuggling operations involve disguising Chinese rare earth materials as other products, such as iron ore and zinc, to evade customs regulations [3][9]. - A Chinese metal chemical company's subsidiary in Thailand reportedly shipped 3,366 tons of antimony products to the U.S. within six months, marking a 27-fold increase year-on-year [5]. Group 2: Economic Implications - The surge in international rare earth prices, which have risen by 200% since 2024, has incentivized some Chinese companies to engage in smuggling for higher profits [11]. - Smuggling profits can reach 3-5 times that of normal trade, creating a vicious cycle that distorts international market prices and attracts more participants into illegal trading [11]. Group 3: Military Supply Chain Vulnerabilities - The smuggling case exposes critical vulnerabilities in the U.S. military supply chain, with a significant reliance on Chinese-produced materials for key weapon systems [12][15]. - Approximately 90% of global rare earth processing capacity is concentrated in China, and over 80% of the U.S. military's rare earth material needs are sourced from China [15]. Group 4: Regulatory Responses - In response to the smuggling issue, China initiated a special action in May 2025 to combat illegal activities related to rare earth exports, including enhanced customs inspections and data sharing with industry associations [19][21]. - New amendments to the Mineral Resources Law have increased penalties for rare earth smuggling, and several cases have already been prosecuted, involving significant quantities of metals [21]. Group 5: Strategic Implications - The ongoing rare earth competition reflects a broader struggle for control over global supply chains, with China leveraging its technological advantages to shape international trade rules [23]. - Efforts by the U.S. to rebuild its supply chain have been largely ineffective, with significant time required to establish independence from Chinese sources [17].
