China supplies roughly 85% of global rare-earth refining and separation and about 90% of magnet manufacturing, a concentration that keeps downstream industries exposed to Beijing’s pricing and export choices. That structure matters for electric-vehicle and wind-turbine supply chains, defence contractors and electronics makers and has produced episodic shocks, including the 2002 closure of the Mountain Pass mine and a 2010 export squeeze after the Senkaku Islands dispute. A supply-chain analysis published in April 2026 presents the most detailed current breakdown, showing China holds about half of identified global reserves, roughly 65% of mining, about 85% of refining and separation, and about 90% of magnet manufacturing. There's no single near-term policy fix; Western projects and undeveloped deposits such as Greenland’s Tanbreez are seen as strategic options, but they will take years to alter the picture.

The rare-earths market is defined by a few stark numbers, and the smallest of those numbers is the one Western industries can't ignore. The April 2026 supply-chain analysis gives a granular map: roughly 50% of identified global reserves sit in China, China performs about 65% of the mining, it carries out around 85% of refining and separation, and it makes about 90% of high-performance magnets. Those figures explain why decisions made in Beijing ripple through factories building electric vehicles, wind turbines and guided munitions around the world.

How concentration translates into leverage

Concentration in the middle of the chain, not merely at the mine mouth, is the critical detail. Mining can be dispersed, but refining and separation are capital- and technology-intensive steps. The April 2026 analysis places China’s dominance squarely at those steps. When refining and magnet manufacture are concentrated in one country, pricing moves and export policy have an oversized effect. Historical episodes make that clear. The U.S. Mountain Pass mine in California closed in 2002 after it lost the ability to compete, a closure linked to the era’s Chinese cost advantage. In 2010, a diplomatic row over the Senkaku Islands coincided with an export restriction that focused Western attention on the risk of supply weaponisation.

Observers point to two tools that have kept Western processing projects struggling to scale. One account argues that deliberate price behaviour played a role. That argument claims Chinese-linked price crashes, calibrated through a regional pricing index, have been used at intervals in the early 2000s, 2010-2011 and 2015-2016 to make Western processing uneconomic and to sap investor confidence. That claim about the pricing index and its ownership is single-source reporting and should be read as such. The other, and more consistently reported, explanation stresses structural cost advantages inside China: lower labour costs, historically looser environmental controls and local-government policies that absorbed some remediation costs. Those factors combined to keep Chinese producers cheaper, especially at the refining and magnet-manufacturing stages.

Practical effects for industry and politics

For manufacturers, the concentration isn't an abstract vulnerability. Firms that need high-performance permanent magnets face supply fragility if Chinese exports tighten. Trade reporting has recorded comments from corporate managers pointing to magnet shortages as disruptive. Tesla’s CEO said at a recent investor presentation that a magnet shortage could slow production of robotics that depend on those magnets, a point that shows how upstream concentration can cascade into factory-floor delays.

Mastheads

Geopolitics plays through supply chains too. Regional press has reported that Beijing has pressed South Korean firms over shipments containing Chinese-sourced rare-earth inputs, a move described in those accounts as a potential threat to South Korea’s exports to the United States.

That reporting isn't corroborated across the full bundle of sources, but it illustrates how suppliers and governments fear politically motivated interference.

Companies trying to build Western refining capacity have repeatedly hit commercial headwinds. One industry account profiles a U.S.-listed processor that opened a new facility in Ohio and suggests it may break the long pattern of failure. That prospective breakthrough appears in single-source industry narrative and should be treated cautiously. What's clear is that scaling refining and magnet manufacture outside China requires sustained capital, patient investors and, in many cases, a willingness to accept higher costs or stricter environmental standards.

Potential alternatives exist but are slow and costly. Greenland’s Tanbreez deposit and other Arctic prospects are flagged in policy circles as large undeveloped sources that Western governments view as strategic options.

Geological potential, however, isn't the same as ready supply. Turning a deposit into a working mine and then building processing plants, social licences and environmental permits is a multiyear effort. Analysts also point to the environmental legacy of Chinese refining in the 2010s as material to why refining was historically concentrated in China, with documented pollution and health impacts around major Chinese rare-earth centres cited as factors that drove Western firms away from refining at home.

That mix of market behaviour, cost structure and environmental history helps explain why Western attempts to reshape the market have delivered only limited results so far. The April 2026 analysis remains the primary quantitative account of where concentration sits inside the chain, and its figures are used repeatedly by policymakers and industrial planners when they assess vulnerability and calculate the cost of onshoring steps in the value chain.

None of the sources identifies a single imminent, dated policy meeting or release likely to shift the balance. Industrial efforts to scale Western refining projects continue, and developers point to Greenland's Tanbreez as a strategic option, but proponents say converting those prospects into processing capacity will take years, and for now China retains roughly 85% of refining and about 90% of magnet manufacture.
