Mountain Pass rare earth mine open pit and processing plant in California
The global rare earth sector faces a major structural shift as China Rare Earth Group enters talks to acquire Shenghe Resources, a move that would deliver an indirect stake in MP Materials, operator of the Mountain Pass rare earth mine in California. This potential transaction is drawing wide attention from mining investors, critical minerals stakeholders and policy analysts, as it brings a Chinese state rare earth enterprise and the US Department of Defense together as shareholders of the same US rare earth producer.
According to Reuters reports, negotiation talks between China Rare Earth Group and Shenghe Resources have been ongoing since early this year. Shenghe Resources currently holds approximately 3% equity in MP Materials. If the acquisition closes, China Rare Earth Group will take control of Shenghe’s overseas asset portfolio, including this minority holding in MP Materials. MP Materials runs the only large-scale commercial rare earth mine and processing complex in North America, supplying rare earth elements for electric vehicle motors, wind turbines, aerospace equipment and defense systems.
What makes this deal distinctive is the existing investment from the US Department of Defense. The Pentagon became MP Materials’ largest shareholder after committing $400 million via preferred stock and warrants last year, aiming to build a domestic US rare earth supply chain and reduce Western reliance on overseas rare earth refining capacityGuruFocus. Market observers note that co-existence of a Chinese state-owned rare earth group and the US defense agency on MP’s shareholder register creates unprecedented geopolitical complexity, and regulatory hurdles may emerge during deal review. MP Materials has repeatedly stated that neither Shenghe Resources nor Chinese entities control its mine operations.

Table 1: Key parties and core deal facts
| Entity | Role in this transaction | Core assets & shareholding |
|---|---|---|
| China Rare Earth Group | Potential acquirer of Shenghe Resources | State-owned major rare earth enterprise, consolidating domestic and overseas rare earth assets |
| Shenghe Resources | Target of acquisition | Holds ~3% minority stake in MP Materials, owns multiple overseas mineral projects |
| MP Materials | US rare earth producer | Operates Mountain Pass mine; US DoD is its largest shareholder |
| US Department of Defense | Major MP shareholder | $400m preferred stock & warrants investment for US rare earth supply security |
China Rare Earth Group’s planned purchase of Shenghe Resources is part of China’s broader rare earth industry consolidation strategy. Beyond the indirect MP Materials holding, Shenghe also owns overseas mineral assets such as Australia’s Peak Rare Earths project. Bringing these overseas holdings under centralized control will strengthen China Rare Earth Group’s global footprint across the whole rare earth value chain, from ore mining to rare earth separation and downstream magnet applications.
Market reactions have been visible since the news release. MP Materials share price declined following media reports, reflecting investor uncertainty over geopolitical risks and regulatory uncertainties surrounding the proposed transaction. At present, there is no confirmed timeline for the acquisition announcement or closing, and it remains unclear whether overseas equity holdings including the MP Materials stake will be retained after the takeover.
For mining investors and critical minerals operators, this case highlights a key trend: rare earth investment is no longer purely a commercial mining play, but deeply intertwined with national supply chain security. Rare earths remain irreplaceable raw materials for clean energy transition and defense hardware, so cross-border equity transactions will continue to face stricter scrutiny from multiple jurisdictions.
As the global energy transition continues to lift long-term rare earth demand, stakeholders across the rare earth value chain will closely monitor the negotiation progress. Whether this indirect stake deal can be completed will have far-reaching implications for cross-border rare earth investment, US critical mineral policy and global rare earth market balance.
