Highlights

• U.S. proposes multilateral price floors for critical minerals to keep non-Chinese producers viable after China's 2024 export restrictions exposed supply chain vulnerabilities across defense, automotive, and semiconductor sectors.
• China controls over 90% of global rare earth processing capacity, with refining infrastructure requiring 5-7 years to build—making price defenses a time-buying measure rather than a structural solution.
• A temporary accommodation between U.S. and China on rare earth access is approaching expiration, with uncertain prospects for extension as Washington pushes allies like South Korea toward a more binding commercial framework.

After China temporarily restricted rare earth exports last year—jolting U.S. defense, automotive, semiconductor, and battery supply chains—Washington is proposing a multilateral trade bloc to blunt Beijing’s leverage. At a February 4 ministerial hosted by Secretary of State Marco Rubio, U.S. officials outlined a plan to defend minimum prices for critical minerals among allies, using tariffs or other measures if China undercuts markets. The objective is straightforward: keep non-Chinese producers economically viable long enough to scale.

What’s Firm—and What’s Still Vapor

Vice President J. D. Vance was unusually direct, arguing that volatile prices and alleged predatory underselling have made Western investment uneconomic. The proposal envisions price floors across production stages, triggered when market prices fall below agreed thresholds. Rubio linked the idea to complementary tools—strategic stockpiles such as Project Vault and coordinated public finance—to give the concept institutional weight.

These signals are real. So is the motivation: China’s export controls exposed how dependent the U.S. remains on rare earth inputs. What remains undefined are the mechanics—specific floor levels, enforcement rules, loss-sharing, and timelines aligned with industrial reality.

The Choke Point Everyone Knows—but Few Can Fix

Hankyoreh gets the central constraint right: refining and separation, not mining. China controls over 90% of global rare earth processing, built on decades of solvent-extraction expertise, precise temperature control, and skilled labor. The reporting notes that building refineries and achieving consistent yields typically takes five to seven years, making hopes for rapid stabilization optimistic at best. Price defenses can buy time; they cannot substitute for chemistry, engineers, and IP.

Allies in the Middle

South Korea’s position (opens in a new tab) captures the dilemma. Closer alignment with a U.S.-led bloc could reduce dependence on China and add resilience, but it carries economic and diplomatic trade-offs. Rubio praised Seoul’s leadership in the Minerals Security Partnership (MSP)—now potentially giving way to a more binding commercial framework—signaling Washington’s intent to move from coordination to enforcement.

REEx Take

This initiative is a credible counterpunch—but it risks overestimating what pricing policy can achieve without midstream muscle. Price floors buy time; processing capability wins markets. Until the West closes the refining gap, China’s dominance remains structural, not tactical.

At present, the United States and China are operating under a temporary accommodation on rare earths, following a limited reprieve granted by Beijing after last year’s export controls disrupted global supply chains. This arrangement has eased immediate pressure on select U.S. industries, but it is explicitly time-bound. As the deadline on this reprieve approaches, the path forward remains uncertain. Whether China extends, modifies, or withdraws this accommodation will have significant implications for pricing, availability, and downstream manufacturing resilience. Rare Earth Exchanges™ will monitor developments closely as the expiration window narrows and strategic signals from both governments emerge.
