G-20 Tries to Box In Critical Mineral Disruption

The G-20 is tiptoeing around China with a sledgehammer. In a draft declaration seen by Bloomberg, leaders called for shielding the global critical-minerals value chain from “unilateral trade measures inconsistent with WTO rules”—a diplomatic way of saying: everyone noticed what China did this year. Beijing’s licensing chokehold on dysprosium, terbium, and other heavy rare earths rattled supply chains from missile makers to EV plants, and the repercussions are still rolling through the system.

Over the past six months, the U.S. and its allies have sprinted to stitch together mine-to-magnet supply chains outside Chinese control. Washington is taking minority stakes in North American rare-earth firms; MP Materials and Aclara are racing to commission heavy-rare-earth separation lines by 2026-2028; and Europe is now openly funding magnet plants to avoid being caught flat-footed again. Even so, the math is bleak—China refines over 90% of global rare earths and produces 94% of the permanent magnets that make missiles maneuver, turbines spin, and EVs accelerate without melting down.

That dominance is exactly what made China’s export curbs so effective. Earlier this year, U.S. defense contractors warned they were burning through “safety stock” of germanium, gallium, and heavy rare earths, with some inputs inflating five or sixty times in price. One supplier flat-out admitted it would miss deliveries if the squeeze continued.

So when the G-20 talks about making mineral supply chains more “resilient,” that’s because Beijing recently reminded everyone how asymmetric the playing field really is.

The draft declaration is non-binding, voluntary, and diplomatic to a fault. It will not unwind Chinese dominance. But it does show how much the strategic conversation has shifted. Critical minerals—once a niche topic for mining conferences—now sit next to Ukraine, Middle East conflicts, and global trade fights on the world’s main stage.

The G-20 isn’t calling China out by name, but everyone already knows who holds the cards—and who’s scrambling to redraw the deck.
