China's escalating critical mineral export controls since 2023 have triggered a coordinated US-Australia-Japan response exceeding $13.5 billion in alternative supply chain investment, eroding Beijing's coercive leverage ahead of the Nov. 10 Busan truce expiration.
China's coercive grip on critical minerals is loosening as a $13.5 billion Western response — reserve financing, project funding and floor-price guarantees — builds alternative supply chains before the Nov. 10 Busan truce expires.
"China did its trading partners a favor by exploiting the chokepoint it spent decades establishing," said Scott Morrison, former Australian prime minister and vice chairman of American Global Strategies, in a Wall Street Journal op-ed. "The more Beijing abuses its leverage, the stronger the case becomes to build around it."
The response spans multiple fronts. Project Vault, launched in February, backs America's first strategic critical-minerals reserve for civilian industry with $10 billion in Export-Import Bank financing plus nearly $2 billion in private capital. The US-Australia agreement grew from $1 billion in October to $3.5 billion across 11 named projects spanning gallium, neodymium-praseodymium, graphite, tungsten, nickel, tantalum and magnesium. The July 2025 MP Materials deal committed $400 million in preferred equity and a $150 million loan, anchored by a 10-year floor price of $110 per kilogram for neodymium-praseodymium and a 10-year magnet purchase commitment.
The stakes are structural. China supplies more than 90 percent of US rare earth demand and controls roughly 85 percent of global rare earth processing capacity. But Xi Jinping's decision to weaponize that position — starting with gallium and germanium export controls in July 2023, expanding to tungsten and seven heavy rare earths in February 2025, and culminating in a global licensing assertion over any product containing Chinese rare earths in late October — has turned supply-chain resilience into a national security priority across the West.
The Erosion of a Chokepoint
China's advantage was never geology or technology — it was economics. Beijing routinely flooded markets with cheap supply, depressing prices and making new Western ventures uneconomical. Global demand for principal magnet rare earths is less than 100,000 tons annually, a fraction of the roughly one billion tons of iron ore Australia exports each year. Small volumes made the market easier to manipulate, but they also mean dominance can be less formidable than it looks.
The 2010 Japan-China rare earth crisis demonstrated both the power and the limits of Beijing's leverage. Japan responded by investing $250 million in Australia's Lynas, now the world's largest producer of separated rare earths outside China. A 2014 WTO ruling against China's export restrictions further constrained Beijing's options. Yet Western end users continued taking cheaper Chinese supply, reinforcing the concentration that became their own vulnerability.
That complacency ended when Beijing began squeezing. The April 2025 cutoff of seven heavy rare earths to US and Western automakers caused production pauses at Nissan and Suzuki. Antimony prices rose 40 percent after export bans. China added 10 US companies to its export-control list in June, including MP Materials.
The Price of Leverage
The US response has moved beyond individual projects to change market conditions. A March 20 executive order directed agencies to fast-track permits and use the Defense Production Act for loan guarantees. A Section 232 investigation followed, and the July 2025 budget boosted the National Defense Stockpile while giving $500 million to the Office of Strategic Capital for credit subsidies capable of supporting up to $100 billion in loans.
A parallel US-Japan framework added pricing measures, financing, offtake, stockpiling and a rapid-response mechanism. Japan is also testing deep-sea rare earth mining near Minamitori Island at depths of roughly 6,000 meters starting in January 2026, while Vietnam plans to ban unprocessed rare earth exports from Jan. 1, 2026.
The Sept. 24 Xi-Trump White House meeting and the Nov. 10 truce expiration will test whether Beijing extends the pause or escalates further. China still controls the processing bottleneck — roughly 85 percent of global rare earth refining and over 90 percent of high-strength permanent magnet production. But the floor price and durable offtake agreements now in place inoculate Western producers against China's price manipulation, changing the economics of alternative supply chains.
"These measures change the economics, enabling Western competitors to challenge China's dominance," Morrison wrote. "Counterintuitively, we have China to thank for it."
