The Scale of Dependency
Why 90% is not a market share but a chokehold
China refines approximately 90% of all rare earth elements processed globally — a concentration of industrial capacity without parallel in any other strategic commodity. ✓ Established Fact The International Energy Agency's 2025 Global Critical Minerals Outlook [1] confirms that China is the dominant refiner for 19 of the 20 critical minerals it analysed, with an average market share of approximately 70% across all categories — and significantly higher in rare earths specifically.
The numbers are stark. China controls roughly 60% of rare earth mining, 90% of separation and refining, and 96% of the world's neodymium-iron-boron (NdFeB) permanent magnets [3]. ✓ Established Fact These magnets are not optional components. They are the functional core of every electric vehicle motor, every wind turbine generator, every guided missile system, and every MRI machine on the planet. Without them, the energy transition stalls and Western defence production lines go silent.
Global mine production of rare earth oxides reached an estimated 390,000 tonnes in 2024, according to the U.S. Geological Survey [2]. ✓ Established Fact But raw tonnage obscures the structural reality. The ore must be refined before it becomes industrially useful — and the refining chokepoint is where China's leverage resides. The United States produced 45,000 tonnes of rare earth concentrate in 2024, valued at $260 million [2]. Almost all of it was shipped to China for processing.
The concentration is intensifying, not easing. The IEA reports that the average market share of the top three mining countries for key energy minerals rose from 73% in 2020 to 77% in 2024 [1]. ✓ Established Fact Projections to 2035 show the average share of the top three refined material suppliers declining only marginally — effectively returning to the concentration levels of 2020 rather than meaningfully diversifying. The structural dependency is not an aberration. It is the equilibrium.
This matters because rare earths are not substitutable in the way that, say, natural gas can replace coal. There is no alternative to neodymium in a high-performance permanent magnet. There is no substitute for dysprosium's ability to maintain magnetic performance at the temperatures inside an EV motor. There is no workaround for samarium-cobalt magnets in missile guidance systems that must function at extreme temperatures [9]. The elements are irreplaceable, and the processing is monopolised.
The strategic vulnerability is not about who digs the ore out of the ground — it is about who can separate 17 chemically similar elements from one another at industrial scale and commercial purity. China spent four decades mastering this chemistry. No Western nation has replicated it. The chokepoint is not geological. It is chemical.
Consider the downstream implications. More than 90% of all electric vehicles sold worldwide use drivetrains built around NdFeB permanent magnets [3]. Every offshore wind turbine uses between 600 kilograms and two tonnes of rare earth magnets in its direct-drive generator. Every smartphone contains small quantities of neodymium, terbium, and dysprosium. The modern economy does not merely use rare earths — it is architected around them. The concentration of processing in a single jurisdiction is not a market inefficiency. It is a systemic risk.
Japan learned this in 2010, when China cut rare earth exports during the Senkaku Islands dispute [10]. ✓ Established Fact Japanese manufacturers — Toyota, Hitachi, TDK — scrambled for supply. The lesson prompted Tokyo to invest billions in recycling, substitution research, and strategic stockpiling. Fifteen years later, Japan remains dependent on Chinese refining. The 2010 shock did not resolve the structural vulnerability. It merely revealed it. The 2025 shock has revealed it again — this time to a far larger audience, with far greater consequences.
The IEA warns that a sustained supply shock for battery metals could increase global average battery pack prices by 40–50% [1]. ◈ Strong Evidence Three-quarters of critical minerals have shown greater price volatility than oil, and half have been more volatile than natural gas. The world built an energy transition on the assumption of stable, affordable rare earth supply. That assumption was always a bet on Chinese goodwill — and in April 2025, Beijing called it in.
The Architecture of Dominance
Four decades of strategic patience
China's rare earth supremacy was not an accident of geology. It was a deliberate, multi-decade industrial strategy that began with a single sentence from Deng Xiaoping in 1992: ✓ Established Fact "There is oil in the Middle East and rare earths in China" [10].
The strategy unfolded in three phases. First, Beijing declared rare earths a "strategic resource" in 1990, prohibiting foreign investment in the sector and issuing export tax rebates to domestic producers [10]. Second, Chinese engineers — many trained in Western universities — perfected the solvent extraction process for separating individual rare earth elements at industrial scale. Third, China offered global manufacturers processed rare earths at prices no Western producer could match, systematically undercutting competitors until they collapsed.
The strategy worked. America's Mountain Pass mine in California — once the world's dominant rare earth source — ceased production in 2002, unable to compete with Chinese pricing or meet tightening US environmental regulations [10]. ✓ Established Fact By 2009, China's share of global rare earth mine production reached 98% [10]. The monopoly was not merely commercial — it was technological. Chinese firms had accumulated decades of proprietary knowledge in separation chemistry that existed nowhere else.
The 2010 Senkaku crisis was the first explicit weaponisation. When Japan arrested the captain of a Chinese fishing vessel near the disputed Senkaku/Diaoyu Islands, Beijing restricted rare earth exports to Japan for two months [10]. Simultaneously, China slashed export quotas by 37%, permitting only 30,259 metric tonnes for export. The result was immediate and devastating: global import prices surged from $9,461 per metric ton in 2009 to $66,957 in 2011 — a 608% increase [10]. ✓ Established Fact
From Deng Xiaoping's 1992 declaration through four decades of subsidised production, environmental cost externalisation, and systematic undercutting of Western competitors, China built a processing monopoly that no market mechanism can rapidly reverse [10]. The WTO ruled against China's 2010 export quotas in 2014 — but Beijing had already moved the leverage from quotas to processing capacity, rendering the ruling moot.
The WTO ruling in 2014 exposed the limits of rules-based trade governance against structural industrial strategy. China removed its explicit export quotas — and nothing changed. The leverage had never truly been about quotas. It was about the fact that 90% of the world's rare earth refining capacity sat inside China's borders, and no international tribunal could compel Beijing to share that capability [12].
The architecture of dominance has a further, less discussed dimension: human capital. Chinese universities have produced thousands of rare earth metallurgists, separation chemists, and process engineers over four decades. This knowledge base does not exist in the West at remotely comparable scale. Chatham House concludes that Western processing technology lags China by decades — not years [12]. ◈ Strong Evidence Building a mine takes 5–10 years. Building a competitive refining industry takes a generation.
The Weaponisation
April 2025 and the export control escalation
On 4 April 2025, the Chinese Ministry of Commerce imposed export controls on seven medium and heavy rare earth elements — samarium, yttrium, gadolinium, terbium, dysprosium, lutetium, and scandium — along with all related compounds, metals, and magnets. ✓ Established Fact The action was a direct retaliatory measure against President Trump's escalating tariffs on Chinese goods [4].
The impact was immediate and severe. As export volumes collapsed in April and May 2025, carmakers across the United States, Europe, and Japan struggled to obtain permanent magnets [4]. Some were forced to cut utilisation rates. Others shut down entirely. The disruption was not theoretical — it arrived in factory silence and empty production lines.
Ford Motor Company became the most visible casualty. The automaker idled its Explorer SUV factory in Chicago for a week in May 2025 due to a shortage of rare earth materials [5]. ✓ Established Fact CEO Jim Farley subsequently revealed the full extent: Ford had shut plants for three weeks because it could not obtain high-performance magnets used in speakers, seat motors, wiper motors, and door actuators. These are not luxury components — they are basic vehicle systems.
We shut down for three weeks because we couldn't get high power magnets. The supply is hand-to-mouth. We're applying for licences one at a time from China's Ministry of Commerce.
— Jim Farley, CEO, Ford Motor Company, June 2025The Ford shutdown was not an isolated incident. Industry groups warned that shortages of rare earth-dependent components — sensors, alternators, seatbelt pretensioners — could halt entire production lines at General Motors, Toyota, and Volkswagen [5]. ◈ Strong Evidence The vulnerability extended far beyond electric vehicles. Rare earth magnets are embedded in the most mundane components of modern automobiles — every car on a Western production line depends on Chinese processing capacity.
The price fragmentation was equally dramatic. European rare earth prices reached up to six times Chinese domestic prices in the months following the April controls [4]. ✓ Established Fact This created a structurally bifurcated market: Chinese manufacturers operated with stable, low-cost inputs while their Western competitors faced volatile, inflated prices. The competitive asymmetry was not incidental — it was the point. Even after trade volumes partially recovered, the pricing differential persisted, systematically eroding the cost competitiveness of rare earth-based products manufactured outside China.
European prices reached six times Chinese domestic levels. The IEA confirms that even after partial trade recovery, the price differential persisted — giving Chinese manufacturers a systematic cost advantage over Western competitors in every product category that uses rare earth magnets [4].
In October 2025, Beijing escalated further. The Ministry of Commerce announced additional export controls covering not only rare earth elements and products but also processing equipment and technologies [11]. ✓ Established Fact This second wave was qualitatively different. Restricting ore and magnets limits supply. Restricting processing technology and equipment limits the ability to build alternative supply. It was the equivalent of OPEC not only cutting oil production but also banning the export of drilling rigs.
The licensing mechanism itself became a tool of leverage. Ford CEO Farley revealed that applications for export licences were being reviewed "one at a time" by China's Ministry of Commerce — a bureaucratic chokepoint that gave Beijing granular control over which companies received supply and which did not [5]. This is not an embargo — it is something more sophisticated. It is a permission system that forces Western manufacturers into individual supplication, creating dependency at the company level rather than merely the national level.
The cascading effects reached beyond automobiles. The consumer electronics industry reported component delays. Wind turbine manufacturers warned of delivery slippages for offshore projects in the North Sea and Baltic. Medical device companies flagged concerns about MRI magnet supply. The April 2025 controls demonstrated that rare earth dependency is not confined to a single sector — it permeates the entire industrial base of advanced economies [4]. ◈ Strong Evidence
Praseodymium-neodymium oxide prices surged from approximately ¥580,000 per tonne in late December 2025 to ¥748,700 — a rise exceeding 29% in weeks [4]. ◈ Strong Evidence Year-to-date gains for key rare earth oxides reached over 40% by late 2025 — one of the most significant price movements in the traditionally stable rare earth complex. Institutions forecast the light rare earth market will maintain a "tight balance leaning towards scarcity" through 2026, with prices likely 15–30% above 2025 levels.
The October 2025 expansion of controls to include processing equipment and technology represents a qualitative escalation. Beijing is no longer merely restricting the flow of processed materials — it is restricting the knowledge and machinery needed to build alternative processing capacity. This is the difference between turning off a tap and removing the plumbing.
The Defence Equation
418 kilograms per fighter jet
Each F-35 Lightning II fighter aircraft — the most expensive weapons programme in history — requires more than 418 kilograms of rare earth materials. ✓ Established Fact These elements are embedded in the aircraft's permanent magnets, radar systems, stealth coatings, and missile guidance technologies [9].
The defence dependency is absolute, not marginal. The F-35 relies on two primary types of rare earth magnets. Samarium-cobalt (SmCo) magnets — approximately 23 kilograms per aircraft — are used in high-temperature applications including missile nose cones and engine components. China produces the entire global supply of samarium [9]. ✓ Established Fact Neodymium-iron-boron magnets, used throughout the aircraft's motor systems and actuators, depend on neodymium, praseodymium, and dysprosium — all subject to the April 2025 export controls.
The US Commerce Department has determined that the United States is nearly 100% import-dependent for the most important types of high-quality rare earth magnets [3]. ✓ Established Fact In 2022, the F-35 programme caused public embarrassment when it was revealed that its engine required a rare earth magnet produced exclusively in China. The Pentagon subsequently secured a waiver to continue using Chinese-sourced components — a tacit admission that no alternative existed.
A platform that consumes 418 kilograms of rare earths per unit, with mission-critical reliance on samarium-cobalt magnets sourced exclusively from China, is now tied to a material stream where that country has deployed export controls explicitly keyed to foreign military affiliation. CSIS projects F-35 deliveries could undershoot planned numbers by 20–30% by mid-2026.
The vulnerability extends across Western defence systems. Rare earth magnets are critical components in Aegis destroyers, Virginia-class submarines, Javelin anti-tank missiles, precision-guided munitions, and every generation of military communications and electronic warfare equipment [3]. The US military's dependence on Chinese-processed rare earths means that in a conflict scenario involving China, the supply of materials needed to build the weapons systems intended to deter or fight that conflict would be controlled by the adversary.
This is not a hypothetical concern. The October 2025 export controls included provisions specifically targeting military end-use applications. Beijing required exporters to certify that rare earth products would not be used in foreign military systems — effectively giving China's Ministry of Commerce a veto over which defence programmes worldwide could access processed rare earths [3]. ◈ Strong Evidence
The scale of the problem defies quick fixes. The F-35 programme alone has over 3,300 aircraft on order across nine partner nations. At 418 kilograms per aircraft, completing the programme requires approximately 1,380 tonnes of rare earth materials — a volume that currently can only be supplied through Chinese refining capacity [9]. Sixth-generation fighter programmes, currently in development by the US, UK, and Japan, are expected to require even greater quantities of high-performance magnets for their advanced sensor suites and directed-energy weapons.
The US Department of Defense's July 2025 investment in MP Materials was explicitly motivated by this defence calculus. But MP's planned capacity expansion — from 1,000 to 10,000 tonnes per year of finished magnets — will take years to reach full production [6]. In the interim, every F-35 rolling off the production line at Lockheed Martin's Fort Worth facility depends on magnets processed in China — a country that has now demonstrated both the willingness and the regulatory apparatus to cut off supply.
The Hidden Cost
Environmental destruction from Myanmar to Malaysia
The global rare earth supply chain is built on environmental devastation that rarely appears in the strategic analyses of Western policymakers. From the illegal mines of Kachin State to the radioactive waste ponds of Malaysia, the true cost of rare earth processing is externalised onto communities with the least power to resist. ◈ Strong Evidence
Myanmar has become the most egregious case. Since the 2021 military coup, rare earth exports to China have surged fivefold, reaching approximately $3.6 billion in 2024 [8]. ◈ Strong Evidence For six consecutive years, Myanmar has been China's top supplier of rare earth imports by value — providing over half of China's total. The mining is concentrated in Kachin State, controlled by a shifting constellation of military-aligned warlords and ethnic armed organisations, with Chinese-backed operations providing capital, equipment, and technical expertise.
The environmental destruction is documented by satellite imagery. Between 2018 and 2024, townships where rare earth mining is concentrated lost approximately 32,720 hectares of subtropical and moist forest — an area roughly the size of Malta [8]. ✓ Established Fact Water analysis has identified severe contamination: extremely acidic pH levels, alarmingly high concentrations of ammonia, chloride, radioactive elements, and toxic heavy metals. The contamination is not contained — toxic runoff from unregulated mines in Shan and Kachin states has polluted rivers flowing into northern Thailand, causing an estimated $40 million in losses to farming, fishing, and tourism.
Yale E360 and Mongabay investigations document 32,720 hectares of deforestation, severe water contamination with radioactive elements and heavy metals, and transnational pollution reaching Thailand's rivers — causing $40 million in damage to agriculture and tourism [8]. Dozens of workers have died in landslides attributed to large-scale deforestation for mining operations.
The human cost is direct. In 2023 and 2024, local media documented the deaths or disappearances of dozens of workers in at least three landslides in Kachin State, attributed to large-scale deforestation undertaken to clear land for mines and supply firewood for furnaces used to convert sediment sludge to dry rare earth oxides [8]. These are not formal mining operations with safety standards — they are artisanal and semi-industrial excavations operated under conditions of armed conflict, beyond the reach of any regulatory authority.
Malaysia presents a different but equally troubling case. Lynas Rare Earths, the Australian company that operates the world's largest non-Chinese rare earth processing facility, has accumulated over 1.5 million tonnes of radioactive waste at its plant in Kuantan, Malaysia [13]. ✓ Established Fact The plant sits on reclaimed peatland that is prone to flooding, located two miles from the sea. Since 2011, communities in Kuantan District have protested against what they describe as unsafe radioactive waste management — the waste contains long-lived radionuclides including uranium and thorium.
In March 2026, Malaysia renewed Lynas's operating licence for ten years but ordered the company to eliminate radioactive waste generation by 2031 [13]. The condition highlights the fundamental tension at the heart of rare earth diversification: the processing that Western nations will not do at home — because of the environmental and health costs — they outsource to countries where regulatory enforcement is weaker. The geography of extraction maps precisely onto the geography of powerlessness.
Every effort to diversify rare earth supply away from China runs into the same obstacle: processing is inherently dirty and dangerous. The radioactive thorium and uranium co-extracted with rare earths must go somewhere. China accepted the cost at home. The West outsources it to Myanmar and Malaysia. The clean energy transition is being built, in part, on radioactive waste ponds in tropical wetlands and deforested hillsides in conflict zones.
China's own environmental record in rare earth processing is severe. Decades of mining and refining in Inner Mongolia's Bayan Obo region — the world's largest rare earth deposit — have created a toxic tailings lake covering more than 10 square kilometres, visible from space. The Chinese government has spent billions on environmental remediation, imposing consolidation of the industry under six state-owned enterprises partly to enforce environmental standards [10]. But the damage of four decades of intensive processing is generational — and the remediation costs are ultimately borne by the communities who lived downstream.
The Response
Billions spent, decades required
Western governments have mobilised historically unprecedented capital to break China's rare earth processing monopoly. The question is not whether the money is being spent — it is whether money alone can compress a multi-decade industrial development timeline into the years that strategic urgency demands. ⚖ Contested
The US Department of Defense's July 2025 partnership with MP Materials represents the most aggressive single intervention. The DoD paid $400 million for a 15% equity stake — making the US government MP's largest shareholder — and issued a $150 million loan to build a heavy rare earth separation facility in California [6]. ✓ Established Fact The Pentagon also committed to a price floor for MP's light rare earth products and guaranteed purchase commitments for all magnets produced over the next decade. The government guarantee helped spur more than $1 billion in additional private financing.
MP's expansion plan is ambitious: increasing magnet production capacity from 1,000 to 10,000 metric tonnes per year through a new '10-X' facility with 7,000 MT annual capacity and expansion of its Independence facility from 1,000 to 3,000 MT [6]. For context, China produces approximately 240,000 tonnes of rare earth permanent magnets annually. MP's planned 10,000 tonnes — if achieved — would represent roughly 4% of current Chinese output.
The US-Australia Critical Minerals Framework, signed in October 2025, established a project pipeline of up to $8.5 billion with near-term joint funding of more than $3 billion expected within six months [7]. ✓ Established Fact Each country committed at least $1 billion in financing to qualifying projects. Lynas Rare Earths — Australia's premier rare earth producer — is constructing a processing facility in Kalgoorlie, Western Australia, and a US facility with DoD support, though its current quarterly output of approximately 3,993 tonnes of total rare earth oxide remains a fraction of Chinese capacity.
The European Union has pursued a parallel but structurally different approach. In March 2025, the European Commission adopted its first list of 47 Strategic Projects to boost domestic raw material capacity [11]. The RESourceEU Action Plan mobilised an additional €3 billion over twelve months, imposed tighter regulatory approval deadlines, and mandated more coordinated industrial action. The EU's Critical Raw Materials Act also targets 25% of key magnet materials to come from recycling by 2030 — an ambitious goal given that current recycling accounts for approximately 1% of global rare earth magnet production [14]. ◈ Strong Evidence
The multilateral dimension accelerated in February 2026, when 54 countries and the European Commission attended the US-hosted Critical Minerals Ministerial [15]. ✓ Established Fact The US proposed a preferential trading zone with enforceable price floors — adjustable tariffs designed to protect member nations from Chinese price manipulation. Eleven bilateral agreements were signed at the event, with negotiations completed with an additional seventeen nations. Japan, the EU, and Mexico were the first economies to express formal interest in the framework.
| Risk | Severity | Assessment |
|---|---|---|
| Processing Capacity Gap | China's 90% refining share cannot be replicated within any near-term horizon. MP Materials and Lynas combined represent single-digit percentages of Chinese capacity. The knowledge gap in separation chemistry is generational. | |
| Defence Supply Chain Disruption | F-35 deliveries face 20–30% shortfall by mid-2026. SmCo magnets for missile guidance are exclusively Chinese-sourced. No alternative production exists at military specification quality. | |
| Price Fragmentation | The 6x price differential between Chinese and European markets gives Chinese manufacturers a structural cost advantage across EVs, wind turbines, and electronics — undermining Western industrial competitiveness. | |
| Technology Transfer Embargo | October 2025 controls on processing equipment and technology restrict Western ability to build alternative refining capacity. This is a capability denial strategy, not merely a supply restriction. | |
| Multilateral Response Fragmentation | Despite 54-nation attendance at the 2026 Ministerial, enforcement mechanisms remain undefined. Historical precedent suggests allied coordination on commodity policy erodes under price pressure. |
The Kuala Lumpur agreements of October 2025 added a Southeast Asian dimension. Malaysia committed to refrain from banning or imposing quotas on rare earth exports to the US, and to expedite development of its critical minerals sector in partnership with American companies [7]. Similar agreements were concluded with Thailand. But Malaysia subsequently clarified that the agreements did not grant the US exclusive access to rare earths — a caveat that underscored the limits of bilateral deal-making in a market where China's processing leverage remains the gravitational centre.
The Debate
Can the West mine its way out?
The central contested question in critical minerals policy is whether Western diversification efforts can break China's dominance within a strategically meaningful timeframe — or whether they represent expensive gestures that will take decades to achieve what Beijing accomplished in a generation. ⚖ Contested
The optimist case rests on genuine momentum. The $400 million DoD investment in MP Materials, the $8.5 billion US-Australia framework, the EU's €3 billion RESourceEU plan, and the 54-nation Critical Minerals Ministerial represent a coordinated Western response without historical precedent [14]. Private capital is flowing: MP Materials leveraged government guarantees into over $1 billion in additional financing. Japan's urban mining programmes are recovering rare earths from electronic waste. New extraction technologies — ionic liquid processing, bioleaching — may eventually bypass Chinese solvent extraction expertise.
The pessimist case is structural. Chatham House projects that even under optimistic scenarios, China's market share in rare earth processing may decline only to approximately 75% by 2028 [12]. ◈ Strong Evidence The mining-processing gap is not a detail — it is the entire problem. China invested four decades building industrial-scale separation chemistry. Western nations are attempting to compress that timeline into years using capital expenditure alone. But money does not create expertise overnight. It does not train thousands of separation chemists. It does not build the operational knowledge that comes from running a solvent extraction plant at industrial scale for decades.
The Case for Western Diversification
Combined US-Australia ($8.5B), EU (€3B), and DoD ($550M) commitments represent the largest coordinated critical minerals investment in history.
Government guarantees and price floors are attracting substantial private investment — MP Materials alone leveraged over $1 billion beyond government funding.
Ionic liquid processing, bioleaching, and advanced hydrometallurgy may bypass Chinese solvent extraction dominance. Japanese urban mining recovery rates are improving.
China's 2010 export restrictions accelerated diversification efforts. OPEC's pricing power was eventually constrained by alternative energy sources. Monopolies attract their own disruption.
54-nation Ministerial, preferential trading zone with price floors, bilateral agreements with 28+ nations — the institutional infrastructure for coordinated action is being constructed.
The Case Against Near-Term Success
Mining is not the bottleneck — refining is. China's 90% refining share reflects four decades of accumulated expertise. No Western facility has achieved equivalent separation purity at industrial scale.
China produces 240,000 tonnes of magnets annually. MP Materials targets 10,000 tonnes at full capacity — 4% of Chinese output. Lynas produces ~16,000 tonnes REO per year. The arithmetic is unforgiving.
October 2025 controls on processing equipment and technology restrict Western ability to acquire Chinese expertise. The knowledge barrier is now legally reinforced.
Rare earth processing is inherently dirty. Western environmental regulations make domestic processing expensive and slow. NIMBYism blocks facilities that China built without community consent.
Chatham House projects China's share declining to ~75% by 2028 at best. Building a competitive refining industry takes a generation — and strategic adversaries do not grant generational timelines.
The Greenland question illustrates the gap between aspiration and reality. Greenland holds 1.5 million tonnes of rare earth reserves and deposits of 25 of the 34 minerals classified as critical by the EU [14]. The US Export-Import Bank has offered $120 million for the Tanbreez rare earth mine. But no economically viable extraction process exists for the eudialyte rock that hosts Greenland's deposits. Arctic infrastructure is virtually nonexistent. Mining experts estimate development would cost billions and take decades — and even if the ore were extracted, it would need refining. Where? In the facilities that do not yet exist.
The recycling pathway faces similar structural constraints. The EU mandates 25% of key magnet materials from recycling by 2030 [14]. ⚖ Contested Current recycling accounts for approximately 1% of rare earth magnet production globally. The economic viability is poor: recycling costs exceed the price of virgin ore from Chinese-controlled sources. Japan leads in urban mining technology, but recovery of individual rare earth elements from mixed waste streams remains technically challenging at industrial scale. The 2030 target is less than four years away.
Breaking China's stranglehold on rare earth processing is likely to take at least a decade. Even the most optimistic projections see China's market share declining only to approximately 75% by 2028.
— Chatham House analysis, October 2025The counter-argument from market optimists — that China's 2010 restrictions ultimately accelerated diversification — is partially valid but historically misleading. The 2010 shock did prompt Mountain Pass to reopen, Lynas to build its Malaysian plant, and Japan to invest in reduction and recycling. But fifteen years later, China still controls 90% of refining. The diversification accelerated by the 2010 shock was real. It was also insufficient. The question is whether the 2025 shock, backed by vastly greater capital, will produce a fundamentally different outcome — or a proportionally larger version of the same incremental progress [10].
The Structural Reality
Chemistry, not geology
The most dangerous misconception in Western critical minerals policy is framing this as a mining problem. It is not. The ore exists on every continent. ◈ Strong Evidence Rare earths are not, despite the name, particularly rare. They are found in commercially viable concentrations in the United States, Australia, Canada, Brazil, Greenland, India, and across sub-Saharan Africa. The problem was never about where the rocks are. It is about who can turn those rocks into separated, high-purity individual elements at industrial scale and commercial cost [12].
Rare earth separation is among the most technically demanding processes in industrial chemistry. The 17 rare earth elements are chemically similar — they occur together in ore, and separating them from one another requires repeated cycles of solvent extraction, each yielding incremental improvements in purity. Achieving the 99.99% purity required for high-performance magnets demands dozens of separation stages, precise temperature and pH control, and deep operational expertise that takes years to develop at each facility [12].
China mastered this chemistry through a systematic, state-backed programme spanning four decades. Chinese universities produced thousands of rare earth metallurgists, separation chemists, and process engineers. The expertise is embedded in institutions, industrial processes, and human capital that cannot be purchased or transferred — particularly now that the October 2025 controls explicitly restrict the export of processing technology and equipment [11]. ✓ Established Fact
China's rare earth dominance rests on mastering industrial-scale solvent extraction to 99.99% purity — a capability developed over four decades. Western processing technology lags by decades, not years. The October 2025 export controls on processing equipment and technology legally reinforce this knowledge barrier [12].
The analogy to oil is instructive but imprecise. Oil's strategic significance rested on a geological lottery — certain nations had it, others did not. The OPEC cartel's power was ultimately limited by the discovery of alternative reserves (shale, deepwater, tar sands) and alternative energy sources. Rare earths are different. The geological distribution is relatively broad. The processing monopoly is the leverage point — and processing monopolies are harder to break than extraction monopolies because they rest on accumulated knowledge rather than geological endowment [1].
The structural reality confronting Western policymakers is a trilemma. First, the energy transition requires exponentially growing quantities of rare earth magnets — the IEA projects demand growth of 3.5x by 2040 for neodymium alone [1]. ◈ Strong Evidence Second, the defence industrial base depends on Chinese-processed rare earths for weapons systems designed to deter China. Third, building alternative processing capacity takes a decade or more — time during which the dependency deepens as demand grows faster than alternative supply.
The February 2026 Critical Minerals Ministerial — 54 nations, a proposed preferential trading zone, enforceable price floors — represents the most ambitious multilateral response to date [15]. But institutional architecture does not produce separated rare earths. Price floors do not train separation chemists. Bilateral agreements do not build solvent extraction plants. The money is flowing. The political will is mobilised. The gap between capital deployed and capability achieved is where the structural reality resides.
Western democracies operate on electoral cycles of 4–5 years. Building a competitive rare earth processing industry — from training chemists to commissioning plants to achieving commercial-grade separation purity — takes 15–20 years. The strategic urgency is measured in months. The industrial timeline is measured in decades. This mismatch is the defining structural vulnerability of the critical minerals challenge.
The evidence suggests that China's rare earth dominance will persist for at least a decade, even under the most favourable assumptions about Western investment and technological development [12]. During that decade, global demand for rare earth magnets will roughly double. The energy transition will accelerate. Defence procurement programmes will expand. And 90% of the refining capacity needed to supply all of it will remain inside the borders of a single nation that has demonstrated — in April 2025 — its willingness to weaponise that advantage.
The implications extend beyond any single commodity. The rare earth case is a template for a broader pattern of critical mineral concentration. Cobalt processing is dominated by China (73%). Lithium refining is concentrated in China (65%). Graphite processing — essential for every lithium-ion battery anode — is 90% Chinese [1]. The energy transition is being built on a foundation of single-country processing dependencies that reproduce, across multiple minerals, the structural vulnerability that rare earths have now made visible.
The question is not whether Western nations will eventually build alternative rare earth processing capacity. They will — economics and national security both demand it. The question is what happens during the intervening decade while that capacity is under construction. During that decade, China retains the ability to impose supply restrictions, fragment global pricing, and grant or withhold the materials upon which the energy transition and Western defence production depend. The leverage is not permanent. But it does not need to be permanent to be decisive.
Deng Xiaoping understood in 1992 what Western policymakers are only now confronting: rare earths are the oil of the 21st century. The difference is that when the oil shocks hit in 1973, the West had decades to develop alternatives. With rare earth processing, the alternatives do not yet exist at scale — and the clock has already started.
