“China controls rare earths” is a common shorthand, but it flattens a much more specific structural reality. China’s dominance across the rare earth value chain isn’t evenly distributed — it’s real but moderate at the mining stage, overwhelming at the separation and refining stage, and near-total at the magnet manufacturing stage. This piece maps out where that concentration actually sits, why it’s concentrated there rather than uniformly, and what real diversification efforts elsewhere in the world are actually up against.
1. Three stages, three very different concentration levels
The rare earth supply chain runs through several distinct stages — mining, separation and refining, and downstream magnet manufacturing — and China’s share looks meaningfully different at each one, according to International Energy Agency (IEA) data:
- Mining: China accounts for roughly 60-70% of global rare earth mining output — substantial, but far from a monopoly, and the stage where global diversification has made the most visible progress.
- Separation and refining: China’s share rises sharply to roughly 91% — the IEA specifically notes Malaysia sits a distant second here.
- Magnet manufacturing (sintered NdFeB permanent magnets): China’s share reaches roughly 94%, per 2024 IEA data — the most concentrated stage in the entire chain.
The structural pattern is the point: China’s dominance intensifies as you move downstream, from raw ore toward the finished, high-value component. This matters because it means efforts to diversify rare earth supply by opening new mines outside China — while genuinely useful — don’t resolve the deeper bottleneck sitting further down the chain, in separation and especially in magnet fabrication.
2. Where within China this is concentrated, and why
China’s rare earth industry isn’t evenly spread across the country — it clusters around two specific resource bases with different characteristics:
- Inner Mongolia hosts major light rare earth deposits and the primary processing infrastructure (calcination and roasting) that feeds separation facilities.
- Jiangxi province, particularly around Ganzhou, sits on the world’s primary source of ion-adsorption clay deposits — the dominant global source of heavy rare earths specifically, including dysprosium and terbium, the elements critical for high-performance NdFeB magnets used in EV motors and wind turbine generators.
Heavy rare earths carry disproportionate strategic weight relative to their volume — they’re needed for magnets that must perform in extreme temperature environments, and they’re considerably harder to substitute or source elsewhere than the more abundant light rare earths mined more broadly across the country.
3. A real, named example of the industry’s consolidation structure
China’s rare earth sector has been deliberately consolidated over decades. Since the 1990s, China’s Ministry of Industry and Information Technology has worked to combine what were once hundreds of separate operators into a small number of large, state-backed groups. A concrete, current example: China Rare Earth Group, formed through a 2021 restructuring, operates through China Southern Rare Earth Group as its Jiangxi-based operational arm — a company with a registered capital of roughly CNY 753 million, whose asset base centers specifically on the ion-adsorption clay deposits that supply much of the world’s heavy rare earth output. The company’s stated scope spans the full value chain: mining, smelting, separation, recycling, and downstream processing — illustrating the vertical integration model that characterizes the leading Chinese producers.
4. Why refining and separation specifically became so concentrated
One analytical perspective worth noting: separation and refining is often described in industry commentary as a business with real drawbacks — relatively thin profit margins, substantial pollution output, and significant local political resistance to hosting these facilities — factors that have made other countries genuinely reluctant to build out this specific stage of the chain, even where they’ve been willing to invest in mining. China’s dominance at this stage reflects, at least in part, decades of accepting these environmental and industrial costs domestically, not purely a technological gap other countries can’t close — though proprietary separation technology refined through extended industrial application, maintained partly through dedicated research institutions since the 1990s, is also a real, separate contributing factor.
5. What real diversification efforts elsewhere are actually up against
Genuine attempts to build non-Chinese rare earth supply chains are underway, and the scale gap they face is informative:
- MP Materials (US) has secured offtake agreements with General Motors and defense contractors for its NdFeB magnet production — but its roughly 1,000 tonnes per year of planned capacity represents about 1% of global NdFeB magnet output (estimated at roughly 100,000 tonnes annually, with China accounting for roughly 85,000 tonnes of that total).
- Lynas Rare Earths operates a genuinely distributed supply chain — the Mt. Weld mine in Western Australia, a separation and refining facility in Kuantan, Malaysia (roughly 10,500 tonnes per year capacity), and a heavy rare earth processing facility under construction in Texas.
- India’s Ministry of Heavy Industries opened global bidding in March 2026 for integrated sintered NdFeB magnet manufacturing facilities targeting 6,000 tonnes per year of combined capacity, backed by a scheme with a financial outlay exceeding 7,200 crore rupees (roughly $865 million).
Even totaling these and similar efforts, global refining and separation capacity outside China currently amounts to less than 40,000 tonnes, concentrated in Malaysia, the United States, Australia, Vietnam, Japan, the UK, France, and Estonia — and downstream magnet-manufacturing capacity outside China is even more limited than that, with cumulative planned finished-magnet output from announced projects reaching only around 18,000 tonnes on a rare-earth-content basis as of early 2026 — roughly one-third of the diversified mining capacity being built. Industry analysts consistently describe magnet production specifically, not mining, as the main bottleneck standing in the way of meaningful supply diversification.
The bottom line
China’s position in the rare earth industry isn’t a single, uniform “control” — it’s a structure that strengthens meaningfully at each stage moving downstream: moderate dominance in mining, overwhelming dominance in separation and refining, and near-total dominance in finished magnet manufacturing. That structure is concentrated within China around two specific resource bases (Inner Mongolia for light rare earths, Jiangxi for heavy rare earths), built through decades of deliberate industrial consolidation. Real diversification efforts are underway globally, but the scale gap remains enormous, and it’s widest precisely at the stage — magnet manufacturing — that matters most for the finished products this material ultimately goes into.
