(AI-generated image)* China Rare Earth Group consolidated control over the country's heavy rare earth separation bottleneck on Oct. 23, 2026, advancing its takeover of four processing units from Shenghe Resources Holding. The state-owned group is acquiring 51% equity in each of the four smelting and separation subsidiaries. The move brings formerly independent merchant refiners directly under central government ownership. The four target companies carry a preliminary asset valuation of 3.25 billion to 3.55 billion yuan ($457 million to $500 million). The 51% stake is valued at 1.66 billion to 1.81 billion yuan ($233 million to $255 million). The State-owned Assets Supervision and Administration Commission established China Rare Earth Group in December 2021 to unify the national ionic clay sector. The state conglomerate already controls 100% of China's heavy rare earth mining quota. Separation represents the most technically challenging choke point in critical mineral supply chains. The chemical solvent extraction process divides mined ore into individual oxides of 99.99% purity. China and its affiliated networks process roughly 98% of the world's separated dysprosium and terbium. Western magnet manufacturers have virtually no domestic alternatives for commercial-scale heavy rare earth separation. The four acquired businesses generated 1.76 billion yuan ($248 million) in revenue during the first half of 2026. They recorded 332 million yuan in combined net profit over the same six-month period. Those processing operations accounted for 36.6% of Shenghe's net profit before intercompany eliminations. The sale strips Shenghe of majority operational control over its most lucrative refining units. Shenghe transfers control of Leshan Shenghe Rare Earth after carving out its non-smelting operations. The transaction also transfers 51% stakes in Quannan Xin Ziyuan Rare Earth, Jiangyin Jiahua New Materials, and Zibo Jiahua New Materials. The target plants include heavy rare earth solvent extraction facilities in Jiangxi and light rare earth operations in Sichuan and Jiangsu. Transferring majority control allows Beijing to dictate feedstock allocations and refined output directly. The transaction follows market scrutiny surrounding Shenghe's global partnerships. Shenghe holds a 7.7% equity stake and a long-term offtake contract with MP Materials, operator of California's Mountain Pass mine. The commercial transfer excludes Shenghe's overseas mining assets and its equity stake in MP Materials. The deal confines state acquisition strictly to domestic refining and separation capacity. Shenghe said the divestment aligns with state integration policies and secures stable raw mineral quotas for the processing lines. Shenghe will retain a 49% minority holding and shift the subsidiaries to equity-method accounting. The buyer, China Rare Earth Group Industrial Development, will execute the buyout in five staged cash installments. The payment structure imposes stringent performance conditions on Shenghe's departing operating teams. The first tranche of 10% comes due upon contract execution. A second payment of 40% requires completion of regulatory filings and merger-clearance procedures. The remaining 50% will be disbursed across three annual installments. Those payments are subject to mandatory deductions if the refineries fail annual audited performance targets. The deal will alter cost structures for permanent magnet manufacturers in Japan, Europe, and the United States. High-performance neodymium-iron-boron magnets require dysprosium and terbium additives to maintain magnetic properties at high engine temperatures. Electric vehicle drive motors consume the bulk of global dysprosium supply. A typical automotive traction motor uses between 50 and 100 grams of dysprosium to prevent thermal demagnetization. Automakers procurement managers had previously turned to semi-independent refiners like Shenghe to negotiate commercial contracts. The integration into China Rare Earth Group effectively eliminates private-sector price buffering. Japan's magnet makers, including Shin-Etsu Chemical and TDK, rely heavily on Chinese solvent extraction plants for purified heavy oxides. Japanese buyers have developed grain-boundary diffusion techniques to reduce heavy rare earth content in motor magnets. European tier-one automotive suppliers face a complete dependence on Chinese heavy rare earth refining. European Union industrial plans mandate domestic mineral processing, but operational heavy rare earth facilities remain years away. China Rare Earth Group has not published plant-by-plant volume data or individual nameplate separation capacities for the four acquired sites. The corporate filings omit specific annual metric tonnage allocations for dysprosium and terbium oxide products. The board of Shenghe approved the equity transfer on Oct. 17, 2026. The transaction requires approval from an upcoming Shenghe shareholder meeting and final asset registration with state regulators. The final valuation report must be completed and submitted to state-asset supervisors before the closing deadline. The five-stage settlement framework extends performance-contingent audits on the acquired separation plants through 2029. ## Impact map | Event | Korea | China | Japan | Global impact | | --- | --- | --- | --- | --- | | State consolidation of four separation refiners | domestic magnet producers face single state seller for imported heavy oxides | CREG secures direct control over 36.6% of Shenghe's processing profit base | Shin-Etsu and TDK face tighter dysprosium quotas and loss of merchant pricing leverage | Western EV motor supply chains lose last independent Chinese separation conduit | ## In this story - **Companies:** China Rare Earth Group, Shenghe Resources - **Tickers:** 600392.SS - **Exposed:** MP Materials, Shin-Etsu Chemical, TDK - **Impact:** Supply Chain, Pricing, Cost Structure ## Primary sources 1. sse.com.cn 2. sasac.gov.cn 3. rareearthexchanges.com 4. eastmoney.com 5. sina.cn --- Cite as: East Asia Brief, "China Rare Earth Group buys four Shenghe separation plants," October 25, 2026. https://eastasiabrief.com/energy-minerals/china-rare-earth-group-buys-four-shenghe-separation-plants-910
