China rare earth mining accounts for approximately 60–70% of annual global rare earth oxide (REO) output, according to the USGS Mineral Resources Program, with dominance extending across mining, chemical separation, and downstream magnet manufacturing. No other country comes close on any of these three dimensions simultaneously.
China Rare Earth Mining — Scale and Dominance
China produced an estimated 270,000 tonnes of REO in 2024, against global output of roughly 390,000 tonnes. The country holds this position not through ore reserves alone — the USA, Australia, and Russia all hold substantial deposits — but through decades of investment in processing infrastructure and state-directed industrial policy.
The Ministry of Industry and Information Technology (MIIT) regulates output through a biannual quota system. In 2025, MIIT set total mining quotas at 270,000 tonnes REO and smelting and separation quotas at 255,000 tonnes — both representing year-on-year increases. Quota allocation is split between the six state-owned groups (see below) and a small number of approved private operators. Undeclared production outside the quota system — historically significant in Jiangxi province — has been substantially reduced by centralisation and enforcement since 2016.
China’s dominance is more pronounced in heavy rare earth elements (HREEs) — dysprosium, terbium, holmium — than in light rare earth elements (LREEs). The ionic clay deposits of southern China are the world’s primary source of separated heavy REEs, and no equivalent resource base exists outside the country at comparable scale or extraction cost.
Key Mining Regions
Bayan Obo, Inner Mongolia is the world’s largest single rare earth deposit by resource tonnage, co-located with iron ore and niobium. It is operated by Baotou Steel (Baogang Group) and is the dominant source of light REEs — primarily lanthanum, cerium, praseodymium, and neodymium. The deposit contains an estimated 800 million tonnes of ore at approximately 5–6% REO, though precise reserve figures are not independently audited. Bayan Obo accounts for the majority of China’s LREE output and has historically been processed as a by-product of iron ore operations, giving Chinese producers a structural cost advantage.
Jiangxi Province (South China) is the critical region for heavy rare earth elements. Ionic adsorption clay deposits — where REEs are weakly bound to clay minerals and recoverable by in-situ leaching with ammonium sulphate — are concentrated across Ganzhou and surrounding counties. These deposits are lower grade than Bayan Obo (typically 0.05–0.2% REO) but yield disproportionately high concentrations of dysprosium, terbium, europium, and other HREEs essential for permanent magnet applications. Environmental damage from legacy leaching operations has been severe; the government has enforced consolidation and remediation since 2012.
Sichuan Province hosts the Maoniuping and Mianning deposits — the second-largest LREE resource cluster in China after Bayan Obo. These carbonatite-hosted deposits contain significant bastnäsite mineralisation and are operated primarily by Shenghe Resources and associated entities. Sichuan production is weighted toward LREEs including cerium, lanthanum, and neodymium.
China’s Six State-Owned Rare Earth Groups
A 2021 restructuring by the State Council consolidated China’s fragmented rare earth industry into six state-owned enterprise (SOE) groups. The consolidation was designed to improve pricing discipline, reduce illegal mining, and concentrate strategic control. All six groups operate under MIIT quota allocation and report through state ownership structures.
The six groups are: China Northern Rare Earth (Bayan Obo, LREE dominant); China Rare Earth Group (southern HREEs, formed by merger of multiple southern producers); China Southern Rare Earth; Guangdong Rare Earth; Baotou Steel Rare Earth; and Shenghe Resources, which additionally holds equity stakes in non-Chinese REE projects including MP Materials’ Mountain Pass operation in California.

Export Controls and Supply Risk
China has systematically tightened export controls on rare earth-adjacent materials since 2023. In October 2023, Beijing restricted exports of gallium and germanium — both critical to semiconductor and defence supply chains. In December 2023, controls were extended to rare earth processing and separation technology, preventing foreign entities from acquiring Chinese expertise in solvent extraction and related refining methods. In April 2025, China suspended export licences for seven categories of heavy rare earth elements and related compounds, including dysprosium, terbium, gadolinium, and lutetium — directly targeting the permanent magnet supply chain serving Western defence and EV manufacturers.
These controls are analysed in detail at China Rare Earth Export Controls: Essential Buyer Guide. For the broader minerals at risk, see Top 10 Critical Minerals at Risk From China Export Controls.
China’s Processing Monopoly
China’s most durable competitive advantage is not in mining but in separation and processing. An estimated 85–90% of global rare earth separation capacity — the chemical step that converts mixed REE concentrate into individual oxides and metals — is located in China. This means that ore mined in Australia, the USA, or Myanmar typically routes through Chinese facilities before reaching magnet manufacturers in Japan, South Korea, or Europe.
Lynas Rare Earths (ASX: LYC) operates the primary rare earth separation facility outside China, processing Australian ore at its Kuantan plant in Malaysia. MP Materials (NYSE: MP) completed Phase 2 commissioning at Mountain Pass in 2024, adding oxide separation capability on US soil. Beyond these two operations, non-Chinese separation capacity remains limited. A full ranking is available at Top 10 Rare Earth Refiners Outside China.
China Rare Earth Mining — Price Implications
MIIT quota decisions are the single most important short-term driver of rare earth spot prices. When quotas tighten or export licences are suspended, domestic Chinese prices and FOB export prices diverge — buyers outside China face both higher prices and supply uncertainty simultaneously. The April 2025 heavy REE export suspension produced immediate upward price pressure on dysprosium and terbium, the two elements most critical for high-temperature permanent magnets.

The Western Response to China Rare Earth Mining
Western governments and allied nations have accelerated investment in non-Chinese rare earth supply since 2020, with pace increasing sharply after the 2025 export controls. The USA, Australia, Canada, and EU member states have each committed capital or offtake support to projects outside China. The current pipeline of Western projects is ranked at Top 10 Western Rare Earth Supply Chain Projects.

How much of global rare earth production does China control?
China accounts for approximately 60–70% of annual global rare earth oxide output, according to USGS data, and an estimated 85–90% of global separation and processing capacity. Its dominance is greatest in heavy rare earth elements sourced from the ionic clay deposits of Jiangxi province.
What are China’s main rare earth mining regions?
The three primary regions are Bayan Obo in Inner Mongolia (world’s largest single deposit, dominated by light REEs); Jiangxi province in southern China (the critical source of heavy REEs including dysprosium and terbium, extracted from ionic adsorption clay deposits); and the Maoniuping and Mianning deposits in Sichuan province (a major secondary source of light REEs).
How do China’s rare earth export controls affect global supply?
China has progressively restricted access to rare earth materials and processing technology since 2023. The April 2025 suspension of export licences for seven heavy rare earth categories — including dysprosium, terbium, and gadolinium — directly constrained supply to Western magnet manufacturers and defence contractors, producing upward price pressure on elements with no near-term substitute supply.
What are China’s six state-owned rare earth groups?
Following a 2021 State Council restructuring, China’s rare earth industry is organised into six SOE groups: China Northern Rare Earth, China Rare Earth Group, China Southern Rare Earth, Guangdong Rare Earth, Baotou Steel Rare Earth, and Shenghe Resources. These six groups hold all MIIT mining and smelting quota allocations and control the majority of Chinese output.
What is China’s role in rare earth processing and separation?
China controls an estimated 85–90% of global rare earth separation capacity — the chemical refining step that converts mixed concentrate into individual oxides used in magnets, catalysts, and electronics. Even ore mined in Australia, the USA, or Myanmar has historically routed through Chinese facilities for separation, giving Beijing leverage over the supply chain well beyond its share of mining output alone.
