Every GPU cooling fan. Every data centre motor. Every robotic actuator. Every server rack. All of them depend on neodymium-iron-boron permanent magnets. China controls roughly 90% of the global processing capacity for the rare earth elements that make these magnets possible.
When China imposed export controls on rare earth elements in April 2025, shipments of rare earth magnets to the United States dropped by 74% within a month. Automakers in the US, Japan, and Europe slowed or closed production lines. The AI industry did not collapse, but the fragility of its material supply chain became impossible to ignore.
This article explains what rare earth minerals are, why they are essential to AI, how China came to dominate them, and what is happening in 2026 to change that dependency.
What Are Rare Earth Minerals?
Rare earth elements (REEs) are a group of 17 metals: the 15 lanthanides plus scandium and yttrium. Despite the name, most are not particularly rare in the Earth’s crust. The challenge is not abundance but concentration: they rarely appear in economically viable deposits, and extracting and refining them is a complex, capital-intensive, and environmentally demanding process.
The rare earths most critical to AI and technology infrastructure are:
- Neodymium and praseodymium (NdPr): The core components of permanent magnets used in electric motors, cooling systems, and hard drives. Every data centre, every electric vehicle, and every industrial robot depends on these.
- Dysprosium and terbium: Added to neodymium magnets to maintain their properties at high temperatures. Essential for high-performance EV motors and defence guidance systems.
- Samarium: Used in high-temperature magnets for aerospace and defence applications.
- Europium, gadolinium, and lutetium: Used in displays, medical imaging, and optical applications.
Beyond rare earths, AI infrastructure depends on other critical minerals that face similar supply concentration risks: gallium (semiconductor manufacture), germanium (optical fibres and solar panels), graphite (battery anodes), and cobalt (battery cathodes).
Why Rare Earths Are Essential to AI Infrastructure
The connection between rare earth minerals and artificial intelligence is not immediately obvious. AI runs on software. But that software runs on hardware that depends entirely on these materials.
Data centres: The GPU clusters that train and run AI models require cooling systems with electric motors, storage systems with hard drive motors, and power infrastructure with transformers. All of these use permanent magnets made from rare earths. A single large-scale AI training data centre might contain tens of thousands of these components.
Semiconductors: Gallium is used in compound semiconductors that appear in 5G infrastructure, satellite communications, and some GPU components. Germanium is used in optical fibres connecting data centres. Both are subject to Chinese export controls.
Robotics and physical AI: The physical AI systems that will characterise the next phase of AI deployment (autonomous vehicles, warehouse robots, surgical robots, manufacturing automation) all rely heavily on rare earth permanent magnets for their motors and actuators.
The scale of dependency: The IEA’s Global Critical Minerals Outlook 2025 found that for 19 out of 20 important strategic minerals, China is the leading refiner, with an average market share of 70%. For rare earths specifically, China accounts for approximately 91% of global separation and refining capacity. China’s dominance is not in raw reserves. It holds only about 35% of global rare earth reserves. The dominance is in the processing stage that transforms ore into usable materials.
How China Built Its Rare Earth Dominance
China’s rare earth dominance is not an accident of geology. It is the result of four decades of deliberate strategic investment.
Deng Xiaoping reportedly said in 1992: “The Middle East has oil. China has rare earth metals.” That comparison turned out to be remarkably accurate. During the Arab oil embargo, OPEC controlled slightly over 50% of global crude oil production, a share that has since fallen below 35%. China now leads production for 30 of the 44 critical minerals for which there are reliable estimates, commands an average market share of over 70% for strategic minerals, and accounts for 93% of magnet manufacturing globally.
Since the 1980s, Beijing invested billions in subsidies and strategic planning to secure its supply chain position. Chinese state subsidies kept domestic rare earth prices low enough to undercut Western competitors. MP Materials in California and Lynas in Australia maintained limited operations, but most Western rare earth processing capacity shut down during the 1990s and 2000s because it could not compete with subsidised Chinese pricing.
By the time Western governments recognised the strategic vulnerability, rebuilding independent supply chains had become a decade-long project rather than a quick pivot. Industry executives consistently note that building a rare earth separation facility takes 12 to 18 months for permitting and construction alone, and meaningful scale requires 5 to 7 years.
China’s Export Controls in 2025-2026: What Happened
The timeline of Chinese export controls on critical minerals accelerated sharply from 2025 onward, driven by escalating US-China trade tensions.
April 4, 2025: China’s Ministry of Commerce imposed export controls on seven heavy rare earth elements and rare earth magnets. Within one month, shipments of rare earth magnets to the US dropped 74% year-on-year. US, Japanese, and European automakers slowed or closed production lines dependent on these inputs.
October 2025: China expanded export controls further, introducing a foreign direct product rule mirroring the US approach used to restrict Chinese semiconductor access. This extraterritorial reach meant products manufactured outside China using Chinese-origin rare earth materials or patented processing technologies could also be subject to Chinese licensing requirements.
January 1, 2026: Updated export licensing controls added samarium, gadolinium, and lutetium to the controlled list, alongside silver and additional materials. A non-automatic licensing system was established allowing Beijing to adjust market access based on geopolitical priorities.
Current 2026 status: A temporary trade truce following October 2025 negotiations paused the most severe restrictions. But the underlying licensing infrastructure remains in place. European firms report licensing approval rates below 25%, with nominal 45-day review periods routinely extending indefinitely. European buyers are paying up to six times the Chinese domestic price for controlled materials.
The Western Response in 2026
The scale of the response in early 2026 represents the most coordinated Western action on critical minerals in history.
US Critical Minerals Ministerial (February 3-4, 2026): The US hosted 54 nations in Washington to coordinate a response to Chinese export controls. The ministerial produced 11 new bilateral supply framework agreements and launched FORGE (Forum on Resource Geostrategic Engagement), a plurilateral coalition aiming to create a preferential trade zone for critical minerals with coordinated price floors.
Project Vault (February 2, 2026): The Export-Import Bank launched a $10 billion initiative, the largest loan in EXIM history, to establish a domestic US strategic reserve for critical minerals modelled on the Strategic Petroleum Reserve. Total commitment including private capital reached $12 billion. Participating companies include Clarios, GE Vernova, Western Digital, and Boeing.
Pax Silica Declaration: A US, UK, and Taiwan agreement to secure end-to-end mineral supply chains for AI data centre infrastructure and drone technology, signed in early February 2026.
EU Critical Raw Materials Act: The EU established a joint purchasing centre and launched a €350 billion+ strategic investment programme. An EU audit in 2026 confirmed extreme vulnerability, with lithium, magnesium, and rare earth elements almost exclusively processed in China despite these efforts.
DoD floor price arrangement: The US Department of Defense entered a floor-price arrangement with MP Materials guaranteeing $110/kg for NdPr oxide with profit-sharing, representing the first step toward price independence from Chinese market manipulation for a US rare earth producer.
The Honest Assessment: How Big Is the Problem?
The supply chain vulnerability is real and significant. The honest assessment is more nuanced than either the most alarmed or most dismissive takes suggest.
The dependency is structural, not temporary. China’s dominance is concentrated in processing, not raw deposits. Even with abundant rare earth deposits in Australia, the US, Canada, and Africa, there is no viable alternative processing infrastructure at scale. Rebuilding independent supply chains would take 20 to 30 years according to most industry assessments, far exceeding any current geopolitical window.
China is using leverage carefully, not maximally. Beijing has consistently imposed temporary, reversible restrictions rather than complete embargoes. Game theory explains why: a complete embargo would force immediate Western investment in alternatives and accelerate decoupling. Partial, reversible controls maintain pricing power, extract strategic concessions, and discourage large-scale alternative investment by keeping the cost-benefit calculation uncertain.
The AI industry specifically has time. Current rare earth stockpiles and existing supply contracts give most AI infrastructure operators a buffer measured in months to years. The acute pressure is more visible in electric vehicle production and defence procurement than in AI data centre operations, where the materials required per unit of compute are smaller.
Diversification is happening but slowly. The ODI projects that by 2035, China will still supply over 60% of refined lithium and cobalt, around 80% of battery-grade graphite and rare earth elements. Even the most aggressive Western diversification programmes will not eliminate Chinese dominance by 2030.
What This Means for the AI Industry
For organisations building and operating AI infrastructure, the rare earth supply situation has specific practical implications.
AI hardware costs will reflect supply chain risk premiums. GPU and server manufacturers sourcing rare earth magnets through diversified non-Chinese supply chains pay more than those sourcing through Chinese-dominated channels. This cost premium flows through to data centre operators and ultimately to AI computing costs.
Physical AI deployment (robotics, autonomous vehicles, manufacturing automation) faces more acute near-term risk than software AI. A chatbot running on existing GPU clusters is not directly constrained by rare earth supply. A robotics factory planning a 2027 production ramp that requires 50,000 rare earth motors faces real sourcing uncertainty.
Supply chain resilience is becoming an enterprise AI risk factor. Organisations building multi-year AI infrastructure plans need to assess rare earth supply chain risk the same way they assess data centre power and cooling risk. It is not a reason to pause AI investment, but it is a factor in site selection, hardware procurement, and supplier diversification.
Final Verdict
The rare earth challenge does not threaten to stop AI development. The materials exist in the ground in many countries. The processing capacity can be rebuilt given sufficient time and investment. The Western response in 2026 is the most serious and coordinated in history.
But the timeline mismatch is real. AI capability is advancing at a pace measured in months. Building alternative rare earth supply chains is a project measured in decades. The gap between these timelines is where the genuine strategic risk lives.
China’s position is not based on geology. It is based on investment, infrastructure, and strategic patience accumulated over four decades. Matching it requires equivalent commitment over equivalent timeframes. The policy tools are now being deployed. Whether the will is sustained long enough to produce real alternatives remains the open question.

Frequently Asked Questions
Why do rare earth minerals matter for AI?
AI runs on hardware that depends on rare earth permanent magnets: GPU cooling systems, data centre motors, storage drives, and transformers all use neodymium-iron-boron magnets. Physical AI systems including robots, autonomous vehicles, and manufacturing equipment are even more directly dependent. China controls approximately 90% of global rare earth processing capacity, making this a significant supply chain risk for AI infrastructure.
Does China have a monopoly on rare earths?
Not on reserves. China holds about 35% of global rare earth reserves. But it holds approximately 91% of global rare earth refining and processing capacity and 93% of rare earth magnet manufacturing. The monopoly is in processing, not geology. This is why the dependency cannot be quickly resolved by simply mining more elsewhere: the processing infrastructure takes years to build.
What did China’s 2025 rare earth export controls do?
China imposed export controls on seven heavy rare earth elements and rare earth magnets in April 2025. Within a month, shipments of rare earth magnets to the US dropped 74% year-on-year. Automakers in the US, Japan, and Europe slowed or closed production lines. A trade truce in late 2025 paused the most severe restrictions, but the licensing infrastructure remains in place with European firms reporting approval rates below 25%.
What is Project Vault?
Project Vault is a US government initiative launched February 2, 2026, led by the Export-Import Bank. It includes a $10 billion loan (the largest in EXIM history) to establish a domestic US strategic reserve for critical minerals, similar to the Strategic Petroleum Reserve. Total commitment including private capital is approximately $12 billion, with participating companies including Clarios, GE Vernova, Western Digital, and Boeing.
How long would it take to replace China’s rare earth dominance?
Industry assessments consistently estimate 20 to 30 years to rebuild fully independent rare earth supply chains at scale. Building a rare earth separation facility alone takes 12 to 18 months for permitting and construction, and meaningful scale requires 5 to 7 years. The ODI projects China will still supply around 80% of battery-grade rare earth elements by 2035 even with current diversification efforts.
Which countries have significant rare earth deposits outside China?
Australia (significant deposits, limited processing), the United States (MP Materials in California is operating), Canada, India, Brazil, Vietnam, and Greenland all have meaningful rare earth deposits. Russia holds significant deposits but is geopolitically unavailable to most Western supply chain strategies. The challenge is not deposit location but processing infrastructure, which barely exists outside China at scale.
