Beijing's deployment of increasingly sophisticated export controls has transformed rare earths from an obscure commodity concern into one of the defining flashpoints of great-power competition.
The Escalation Timeline
China's rare earth export control regime has evolved through carefully calibrated escalations: In December 2023, China announced a ban on rare earth extraction and separation technology exports. On April 4, 2025, the Ministry of Commerce introduced export controls on seven heavy rare earth elements (samarium, dysprosium, gadolinium, terbium, lutetium, scandium, and yttrium) plus all related compounds, metals, and magnets, in retaliation for President Trump's new tariffs. In May 2025, a 90-day tariff truce was reached in Switzerland. Yet stability proved short-lived: U.S. manufacturers soon began shutting down production amid ongoing shortages, as China delayed the issuance of export licenses despite not formally abandoning the deal. On October 9, 2025, China significantly expanded its export control regime, the strictest to date. The new controls now include extraterritorial provisions, requiring export licenses for products made outside China if they contain Chinese-origin materials or are produced using Chinese technologies. This marks the first time China has applied the foreign direct product rule, a mechanism long used by Washington against China in semiconductors, now mirrored back. On November 7, 2025, China suspended the October 9 controls for one year until November 10, 2026, but the April 2025 controls remain fully in force. China's expanded measures and incremental approach establish the legal infrastructure for systematic export controls over rare earth supply in the long term, rather than a one-off tactical maneuver.
The Scale of China's Dominance
The IEA's Global Critical Minerals Outlook 2025 showed that for 19 out of 20 important strategic minerals, China is the leading refiner, with an average market share of 70%. For rare earths the concentration is even more extreme: 65–70% of mining and 85–90% of refining and processing. The most strategically significant concentration is in permanent magnets. Two decades ago, China accounted for around 50% of sintered permanent magnet production. This share has risen significantly to 94% today. Noveon Magnetics is currently the only manufacturer of rare earth magnets in the United States. Only a handful of mines outside China and Myanmar are operating at scale, and newly announced projects typically have long lead times, averaging around eight years. Refining development is even more nascent, with only a few industrial-scale facilities operating outside China, in Malaysia, the United States, and Estonia.
The Impact on Industry
Export volumes fell sharply in April and May 2025. China's neodymium-praseodymium oxide benchmark soared approximately 40% in August 2025 after a shipment disruption. Carmakers in the United States and Europe struggled to obtain permanent magnets, forcing some to temporarily shut down factories. The system of case-by-case licensing effectively grants authorities discretion to evaluate each shipment's end use and destination, adding uncertainty that no amount of inventory management can fully mitigate.
The Western Response
In July 2025, the Department of Defense invested $400 million in equity into MP Materials, making the U.S. government the company's largest shareholder, with a 10-year price floor commitment of $110 per kilogram for NdPr products. A $150 million loan was extended to expand MP Materials' Mountain Pass, California facility with heavy rare earth separation capabilities. Noveon Magnetics and Lynas Rare Earths announced a strategic partnership to build a domestic permanent magnet supply chain. New capacity is emerging across allied economies: Arafura's Nolans Project in Australia, Vital Metals' Nechalacho mine in Canada, REEtec's plant in Norway, and expanded magnet-grade production in Japan through Shin-Etsu Chemical and Hitachi Metals. When the United States and Australia signed a new $8.5 billion rare-earths agreement in October 2025, it underscored the scale of investment Western governments now consider necessary. But mining is complex and difficult. Establishing a supply chain is a "multi-decadal situation."
The Strategic Calculus
China's rare earth export controls have been described as a "one-shot bazooka" — potent but with inherent limitations. Beijing favors calibrated pressure over outright disruption, maintaining enough dependency to preserve leverage without triggering a permanent exodus from its processing ecosystem. But the West faces a stark reality: China is aggressively entrenching upstream and midstream control globally, while the U.S. and allies still lack matching mines, processing plants, and sustained capital. Diversification will require mines, processing plants, magnet factories, and sustained capital, all built faster than Beijing can tighten control.
Outlook
The November 2026 expiration of China's suspension looms as a defining deadline. Rather than operating as commodities subject to market forces, rare earth elements have become strategic assets where access depends on geopolitical relationships and regulatory frameworks controlled by a single dominant supplier. The era of cheap, freely traded rare earths is over. What comes next will be shaped not by commodity traders, but by defense ministries, trade negotiators, and the industrial policy architects who are now racing to build the supply chains that should have been built a decade ago.
