Rare Earth Power Is Won in Processing, Not the Mine
United States | China
China’s advantage is the result of long-term planning. For decades, Beijing built capacity not only in rare earth mining, but in the harder middle stages: separation, refining, metal-making and magnet production. That is where the real monopoly sits. Recent estimates place China at roughly 70% of global rare earth mining, around 90% to 91% of separation and refining, and more than 90% of permanent magnet manufacturing. In heavy rare earth refining, including materials such as dysprosium and terbium used to make high-performance magnets withstand heat, China’s control is estimated near 99%.
This is why rare earths fit so neatly into the logic of The Art of War. China does not need to win by direct confrontation if it can shape the battlefield before the confrontation begins. By controlling the inputs that others need for defence, AI infrastructure, robotics, electric vehicles and wind power, Beijing creates strategic dependency. Export controls then become a signalling tool: not a full embargo, but a reminder that supply can be slowed, licensed, delayed or redirected.
The United States understands the danger, but rebuilding a supply chain is slow. America has the Mountain Pass mine and is investing in companies such as MP Materials and Phoenix Tailings, while the Pentagon and allies are supporting domestic processing and magnet capacity. The G7 has also moved toward a critical minerals alliance designed to reduce dependence on any single supplier. But the challenge is not just opening mines. It is recreating decades of Chinese processing know-how, environmental tolerance, low-cost capacity and downstream integration.
The most important rare earths in this tug of war are not necessarily the rarest. Neodymium and praseodymium are central to NdFeB permanent magnets used in EV motors, wind turbines and defence systems. Dysprosium and terbium are smaller-volume but strategically critical because they improve magnet performance at high temperatures. Samarium is also important in specialised defence and aerospace magnets. Control over these materials gives China leverage far beyond the dollar value of the rare earth market itself.
The United States is trying to convert vulnerability into industrial policy. China is trying to preserve its upstream and midstream dominance while using export controls as strategic pressure. The result is a long contest measured not in months, but decades. China planned early and built the battlefield. The US is now trying to build an alternative supply chain while still standing inside China’s shadow.
Technical processing angle: the real bottleneck is not simply ownership of ore. A rare earth plant must beneficiate the mineral, crack bastnaesite or monazite with acid or alkali chemistry, remove radioactive and iron-bearing impurities, separate similar lanthanides through long solvent-extraction circuits, then convert oxides into metals, alloys and magnet feedstock. China built scale in these middle steps over decades, which is why new mines outside China still need separation, metallisation and magnet customers before they become strategically useful.
