China Strikes Back at the Pentagon’s Rare Earth Bet


On Monday morning, while Washington was processing Vice President J.D. Vance’s return from Switzerland and the Islamabad MOU’s fragile diplomatic gains, Beijing quietly moved against 10 American companies with a precision that deserves more attention than it is receiving. China’s Ministry of Commerce placed the firms on its export control list, barring Chinese dual-use exports to them and extending that prohibition to any third-country entity that tries to transfer Chinese-origin goods on the behalf of those countries. The list includes drone makers, aerospace contractors, and two companies that sit at the center of America’s most consequential industrial security project: MP Materials and USA Rare Earth, the two firms Washington has spent hundreds of millions of dollars building into a domestic alternative to Chinese rare-earth dominance.

The timing is not coincidental. Four days before China moved, the Pentagon had conditionally committed $725 million in senior-secured debt to Energy Fuels, another rare earth processor, to close what it described as the most urgent gap in the American defense supply chain. Beijing’s sanctions were a direct response: a message, delivered in the language of export controls, that the American strategy of building rare earth independence is visible, understood, and being actively countered.

The Iran war dominated four months of geopolitical attention and consumed an enormous quantity of American military and diplomatic capital. The rare-earth contest has been unfolding for years with almost no comparable public engagement, and its consequences are at least as significant. Seventeen metallic elements, found in abundance across the earth’s crust but often difficult to process, are essential to the motors in electric vehicles, the magnets in wind turbines, and the guidance systems in F-35 fighter jets, Tomahawk cruise missiles, and Virginia-class submarines. China controls approximately 60 percent of global rare earth mining and more than 85 percent of the processing infrastructure that converts mined ore into usable materials.

This dominance was not accidental. Over decades, China’s state-directed economy tolerated environmental costs that Western regulatory frameworks prohibited, systematically undercut prices to drive competitors out of the market, and built processing expertise that took generations to accumulate. The result, as the International Energy Agency noted , is that existing and planned rare earth production capacity outside China will cover only about a quarter of global refining needs and less than a fifth of projected magnet demand by 2035. That gap is what makes the contest between MP Materials and Beijing something more than a corporate dispute. MP Materials operates the Mountain Pass mine in California, the only commercially operating rare-earth mine in the United States. The Pentagon took approximately 15 percent equity in the company in 2025, committed to a price floor of $110 per kilogram of neodymium-praseodymium, and pledged to purchase the output of a new magnet facility. The U.S. government, in other words, has made MP Materials a ward of the defense-industrial state. Beijing has now placed that ward on a sanctions list.

What makes China’s latest action strategically significant is not any single measure in isolation. It is the combination of simultaneous moves that reveals the coherence of Beijing’s approach. On the same day that China sanctioned MP Materials and USA Rare Earth, its Ministry of Finance barred 46 American companies from government procurement in China. That list includes Lockheed Martin, Raytheon, Boeing Defense, and General Dynamics. These are the primary defense contractors whose weapons systems depend on the rare-earth magnets that MP Materials and USA Rare Earth are to supply. Beijing has, in a single set of simultaneous announcements, targeted both the upstream suppliers trying to break its monopoly and the downstream consumers those suppliers were built to serve.

This is not a reactive tit-for-tat. The coordination is too precise. It reflects a Chinese strategic calculation that the American rare earth independence project is sufficiently advanced to warrant direct disruption, and that the Iran war, the Switzerland talks, and the domestic political noise generated by UK Prime Minister Keir Starmer’s resignation provide adequate cover for the move to land without the attention it merits.

The United States and China have negotiated a partial suspension of China’s strictest rare earth export controls that runs until November 10, 2026. After that date, the full force of restrictions imposed in October 2025 takes effect. Even under the partial truce, exports of yttrium, dysprosium, and terbium to the United States are already running approximately 50 percent below their pre-restriction baseline. November 10 is not an abstraction. It is a countdown.

According to conventional wisdom, the most recent sanctions are largely symbolic because the targeted American defense companies have little direct business in China. That reading is technically accurate and strategically inadequate. The sanctions are not designed to damage the named companies’ China revenues, which are minimal. They are designed to signal to every other government and corporation in the world that China is willing to weaponize its rare-earth position against the specific firms and programs that threaten that position. The message to allied governments considering joining the American-led FORGE framework , a 55-country coalition designed to reduce collective dependence on Chinese critical minerals, is that participation carries a cost.

Whether that cost is prohibitive depends on what alternatives exist. The Pentagon’s $725 million loan to Energy Fuels this month, combined with its earlier investments in MP Materials and Lynas, represents the largest single-week commitment to rare-earth midstream capacity in American history. It is also, by the IEA’s own analysis, still far short of what is needed. The gap between what America is building and what it needs cannot be closed in months. It requires years of investment and political will sustained across administrations.

The Iran deal took four months and captured the world’s attention. The rare-earth contest has been running for a decade and is only now beginning to generate the institutional response its urgency demands. Beijing moved this morning to slow that response down. The more relevant question is not whether Monday’s sanctions were symbolic. It is whether Washington is moving fast enough to make them irrelevant before November 10.

The concrete answer to that question has a specific shape. A single F-35 fighter jet contains over 900 pounds of rare-earth materials, including approximately 50 pounds of samarium-cobalt magnets used in its missile nose cones, actuators, and electronic warfare systems. China produces the entire global supply of samarium. A Virginia-class submarine requires roughly 9,200 pounds of rare earths. An Arleigh Burke-class destroyer needs 5,200. These are not future vulnerabilities. They are current production dependencies. Analysis cited in Ti22 Strategies suggests that under a full application of China’s 2025 rare earth licensing regime, F-35 deliveries could undershoot planned numbers by 20 to 30 percent by mid-2026, with Lockheed Martin’s Fort Worth assembly lines at risk of idling for 12 to 18 weeks per 50-jet production batch if samarium-cobalt alloys are delayed.

The Pentagon’s magnet qualification program for F-35-specific rare-earth applications is targeting mid-2027 certification. Since China’s partial suspension expires November 10, 2026 , there’s a seven-month gap between when Beijing can fully restrict supply and when American alternatives are certified for use. In that window, the two companies Washington has spent hundreds of millions of dollars building to close this gap—the same two companies Beijing sanctioned on Monday morning—are the only domestic buffer.

This is what a supply-chain war looks like before it becomes a shooting war. It is conducted through export control lists, licensing regimes, and procurement bans. It happens on mornings when the news cycle is consumed by resignation speeches in London and diplomatic press conferences in Switzerland. It does not announce itself.

Beijing understands this. The question is whether Washington does.
