China's Critical-Minerals Controls Distort Markets and Fuel Resource Nationalism

Beijing's export controls on rare earths and other specialized metals are distorting global markets and fueling resource nationalism, as governments that depend on Chinese processing move to secure alternative supply. China dominates not the mining of these minerals so much as their refining, the stage where most of the world's capacity sits inside its borders, giving it leverage over inputs essential to electric motors, wind turbines, and precision weapons.

The picture is not one-sided. Chinese scientific coverage has highlighted the country's own vulnerabilities in certain rare-earth categories, a reminder that dominance in processing does not guarantee dominance in every mineral or at every stage. That asymmetry is precisely what makes minerals diplomacy volatile, because each side has bottlenecks it can exploit and gaps it must cover.

The result is a race for parallel supply chains. Western governments are subsidizing domestic mining and refining, striking offtake deals with producers in Africa, Australia, and Latin America, and building stockpiles, an expensive duplication that raises costs across the industries that use these metals. For producing nations, the leverage works in both directions, encouraging them to demand more value from what they extract rather than shipping raw ore.
