Washington, DCย The US government has announced a strategic investment to become the largest shareholder in the countryโs only operational rare earths mine, Mountain Pass, California, marking a significant shift in efforts to secure domestic supply of these critical materials essential to modern technology and national security.
US Department of Defense Secures Rare Earths Supply with $400 Million Investment
MP Materials, the owner and operator of the Mountain Pass mine, has entered into a comprehensive agreement with the US Department of Defense (DoD) to reduce Americaโs heavy dependence on Chinese imports of rare earth elements (REEs). As part of the deal, the DoD will purchase $400 million in newly issued shares from MP Materials, making it the mineโs largest shareholder.
The agreement guarantees MP Materials a minimum price of $110 per kilogram for its neodymium and praseodymium output two of the most critical rare earth elements used globally in the production of high-strength permanent magnets. These magnets are integral components in electric vehicles, wind turbines, military radar systems, and medical devices such as MRI scanners.
James Litinsky, founder and CEO of MP Materials, called the initiative โa decisive action by the [Trump] administration to accelerate American supply chain independence,โ emphasizing the strategic importance of reshoring the US rare earths industry.
Addressing Chinaโs Dominance in the Global Rare Earths Market
China currently dominates the rare earth sector, controlling roughly 70% of global rare earth mining and about 90% of refining capacity, a position achieved over decades through substantial government support and industrial policy. This concentrated control has been instrumental in fueling geopolitical tensions, particularly in US-China trade relations.
โThe overwhelming reliance on China for rare earth processing has posed substantial strategic risks to the US,โ said Dr. Lisa Murray, a senior analyst at the Center for Strategic and International Studies. โThe Mountain Pass investment is a critical step towards mitigating supply chain vulnerabilities.โ
Historically, MP Materialsโ output was mainly sold to Shenghe Resources, a Chinese government-linked entity, which refined the rare earth concentrates in China. However, escalating tariffs amid the US-China trade war disrupted this arrangement. China imposed 125% tariffs on US goods in retaliation to President Trumpโs 145% tariffs on Chinese imports, making the export of rare earth materials from Mountain Pass to China commercially untenable.
In response, MP Materials ceased shipments to China earlier this year, citing not only economic impracticality but also national security concerns.
Building Domestic Refining Capacity: A Key Move
A pivotal component of the new agreement requires MP Materials to construct a processing facility on US soil to convert raw rare earth concentrates into usable materials. The precise location remains under review, but it will cater to both defense and commercial sectors. This vertical integration aims to establish a fully domestic rare earth supply chain from extraction to refinement reducing reliance on foreign intermediaries and vulnerabilities to supply disruptions.
โThis expansion will help the US regain control over an essential segment of the rare earth value chain that China currently monopolizes,โ explained Helen Jiang, a materials scientist at the National Renewable Energy Laboratory. โDeveloping domestic refining capacity is vital for ensuring the security of supply for critical industries.โ
Strategic and Economic Implications
Rare earth elements are indispensable for modern technological innovation, powering everything from smartphones and electric motors to advanced military systems. Americaโs dependence on importsโprimarily from Chinaโhas long been a strategic liability.
The trade war catalyzed changes in global rare earths dynamics. Beijingโs introduction of an export licensing regime directly limited the flow of these materials to US manufacturers, prompting Washington to seek diversified sources and domestic production.
The $400 million DoD investment signals a continued commitment to securing supply chains aligned with the broader strategic vision of making the US economy more resilient and self-reliant, particularly in sectors critical to national security.
Dr. Steven Rogers, an expert in supply chain economics at Georgetown University, notes, โBeyond defense, this initiative has profound implications for the US industrial base, particularly with the ongoing transition to clean energy and electric transportation, both of which are heavily reliant on rare earths.โ
International Reactions and Broader Context
Beijingโs near-monopoly on rare earths has drawn ire not only from Washington but also from European policymakers. The European Parliament recently passed a resolution condemning Chinaโs export controls as โunjustifiedโ and โcoercive,โ urging the European Commission to expedite implementation of the Critical Raw Materials Act. This legislation seeks to enhance Europeโs independent access to critical raw materials like rare earths.
During a recent visit to Germany, Chinaโs Foreign Minister Wang Yi defended the export controls as Chinaโs โsovereign rightโ and a โcommon practiceโ for countries managing dual-use goods with both commercial and military applications.
Future Outlook: Towards Strategic Autonomy
The US initiative to bolster its rare earth supply chain via MP Materials is part of a broader trend to recalibrate global supply dependencies. Experts expect the move to catalyze further investments in mining, processing, and recycling sectors domestically.
โWeโre witnessing the start of a new chapter in critical minerals security,โ said Maria Lopez, policy director at the Minerals Security Partnership. โEnsuring stable, diversified supply chains is vital not just for economic competitiveness but for geopolitical stability.โ
The new facility under development by MP Materials sets a precedent for public-private partnerships in addressing strategic resource vulnerabilities. Over the next decade, US policy experts anticipate increasing federal involvement in critical mineral supply chains through investment, regulation, and research support.
Background: Rare Earths and the US-China Trade War
Rare earth elements encompass 17 chemically similar metals vital for high-tech manufacturing and clean energy technologies. Despite their name, these elements are relatively abundant in the earthโs crust but are challenging to mine and refine economically.
The US once led global production but saw its industry decline amid environmental concerns and Chinese competition. By the 1990s, nearly all US rare earth supply had been supplanted by imports from China.
The ensuing geopolitical implications gained prominence during the Trump administrationโs trade measures, which aimed to counter Chinaโs strategic use of economic instruments. Securing rare earths domestically is seen as crucial to mitigating risks of supply disruptions in potential future conflicts or diplomatic standoffs.
