Part 4: The Rare Earth Monopoly
China Controls 80% of Rare Earth Processing—Every Wind Turbine and EV Depends on Them
You drive an electric vehicle. The motor contains permanent magnets made with neodymium and dysprosium—rare earth elements. Your smartphone screen uses europium and terbium for color. The wind turbines generating renewable electricity contain 200-600 kg of rare earth magnets per megawatt. The F-35 fighter jet contains 417 kg of rare earths. Tomahawk cruise missiles need samarium-cobalt magnets. Every advanced technology—EVs, wind turbines, electronics, military systems—depends on rare earth elements. And China controls the supply. Not because China has all the rare earths (they don't—the US, Australia, and others have significant deposits). China dominates because they control processing—the toxic, expensive, environmentally destructive process of refining rare earth ores into usable materials. China processes 80-90% of global rare earths. The US? Less than 5%. This wasn't always true. In the 1990s, the US was the world's largest rare earth producer (Mountain Pass mine, California). Then China undercut prices, US mines closed, processing moved offshore. Now, even US-mined rare earths get shipped to China for processing. The result: China can restrict rare earth exports anytime—and they have (2010, against Japan during territorial dispute). For two months, rare earth prices spiked 10x, Japanese manufacturers scrambled, and the world learned a lesson about supply chain vulnerability. That was a warning shot. A full embargo would cripple Western manufacturing (EVs, wind turbines, electronics) and military production (jets, missiles, satellites) within months. Welcome to the rare earth monopoly—the most strategically critical materials you've never heard of.
What Rare Earths Actually Are: 17 Critical Elements
Rare earth elements (REEs) are a group of 17 chemically similar metallic elements. Despite the name, they're not particularly rare—some are more abundant than copper or lead.
The 17 Rare Earth Elements
Light rare earths (more abundant):
- Lanthanum (La), Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu)
Heavy rare earths (less abundant, more valuable):
- Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb), Lutetium (Lu), Yttrium (Y), Scandium (Sc)
Why They're Called "Rare"
Not because they're scarce, but because they're difficult to extract and separate.
Rare earths occur mixed together in ores. Separating them requires complex chemical processes because they're chemically similar (hard to isolate individual elements). The process is:
- Toxic: Uses acids, solvents, produces radioactive waste (thorium, uranium co-occur with rare earths)
- Expensive: Multiple processing stages, energy-intensive
- Environmentally destructive: Tailings ponds, water pollution, radioactive waste disposal
This is why China dominates. China accepted the environmental costs (loose regulations, willingness to sacrifice local environments) and invested in processing capacity while Western countries shut down operations (environmental regulations, higher costs, NIMBY opposition).
MINING (Production by country):
• China: 70% (240,000 metric tons)
• US: 15% (43,000 tons, mostly Mountain Pass)
• Myanmar: 7% (26,000 tons, often smuggled to China)
• Australia: 6% (20,000 tons)
• Others: 2%
PROCESSING/REFINING (Critical chokepoint):
• China: 85-90% of global processing
• Malaysia: 5% (Lynas plant, Australian-owned)
• Estonia: 2%
• US: 1-2% (minimal, mostly R&D scale)
• Everyone else: <1%
PERMANENT MAGNET PRODUCTION (End products):
• China: 90%+ of rare earth magnets
• Japan: 5%
• Others: <5%
TOTAL MARKET SIZE:
• Rare earth oxides: $8-10 billion/year
• Rare earth magnets: $15+ billion/year
• Applications using rare earths: $trillions (EVs, wind, electronics)
THE CHOKEPOINT:
China doesn't have a mining monopoly (70% is significant but not total).
China has a PROCESSING monopoly (85-90%).
Even US/Australian-mined rare earths often get processed in China.
Processing = the strategic chokepoint.
Why Rare Earths Matter: Wind Turbines, EVs, Military
Rare earths are in everything critical to energy transition and national security.
Wind Turbines: 200-600 kg of Rare Earths Per MW
Where used: Permanent magnet generators (most efficient, used in most modern turbines)
Key elements: Neodymium (Nd), Dysprosium (Dy), Praseodymium (Pr), Terbium (Tb)
Amount needed:
- Typical 3 MW offshore wind turbine: 600+ kg of rare earth magnets
- Each kg of magnets contains ~300-400g of neodymium, 30-50g of dysprosium
Scale: Global wind capacity (2025): 1,000+ GW. New installations: 100+ GW/year. That's 20,000-60,000 metric tons of rare earths annually just for new wind turbines.
Problem: China makes 90%+ of the rare earth magnets used in wind turbines.
Electric Vehicles: Permanent Magnet Motors
Where used: EV motors (most efficient design uses permanent magnets)
Amount per vehicle: 1-2 kg of rare earth magnets (containing ~300-600g neodymium, 50-100g dysprosium)
Scale: 15 million EVs sold in 2024. Projected 30+ million by 2030. That's 15,000-30,000 metric tons of rare earth magnets annually.
Note: Some EVs use induction motors (no rare earths), but permanent magnet motors are more efficient (longer range). Tesla uses both depending on model.
Consumer Electronics
Smartphones: Small amounts of multiple rare earths:
- Neodymium (speakers, vibration motors)
- Europium, terbium, yttrium (screen phosphors for color)
- Lanthanum (camera lenses)
Laptops, tablets, headphones: Similar uses (speakers, screens, cameras)
Scale: 1.5+ billion smartphones sold annually. Small amounts per device, but massive aggregate demand.
Military Applications: F-35, Tomahawks, Satellites
This is where rare earth dependency becomes a national security issue.
F-35 fighter jet: 417 kg of rare earths per aircraft
- Samarium-cobalt magnets (jet engines, actuators—can handle high temperatures)
- Neodymium magnets (electronics, sensors)
- Terbium, dysprosium (targeting systems, displays)
Tomahawk cruise missiles: Guidance systems use samarium-cobalt magnets
Satellites: Solar panels, electronics, sensors all use rare earths
Guided munitions: Precision-guided bombs, missiles all need rare earth magnets and electronics
The vulnerability: US military depends on rare earths. China supplies 80%+ of processed rare earths. In a conflict, China could cut supply, crippling US military production.
The Pentagon has stockpiles, but they're limited (classified amounts, but estimated months of supply, not years). Building alternative supply chains takes 5-10 years.
How China Captured Rare Earth Dominance
China didn't have a rare earth monopoly in the 1980s. They built it deliberately through industrial strategy.
Phase 1: Develop Domestic Capacity (1980s-1990s)
Deng Xiaoping (1992): "The Middle East has oil, China has rare earths." Recognition that rare earths were strategic resources.
China invested in:
- Mining (Bayan Obo, Inner Mongolia—world's largest rare earth deposit)
- Processing facilities (Baotou, Inner Mongolia became rare earth processing hub)
- Subsidies for rare earth companies
- Accepting environmental costs (loose regulations, minimal cleanup)
Phase 2: Undercut Global Competition (1990s-2000s)
Chinese rare earth producers flooded global markets with cheap rare earths (prices 30-50% below Western producers). Western mines couldn't compete:
- Mountain Pass (California): US's largest rare earth mine, closed 2002 (couldn't compete on price + environmental compliance costs)
- Australia: Several mines shut down
- Other countries: Rare earth production declined globally as China dominated
Result by 2010: China produced 95%+ of global rare earths, processed 95%+.
Phase 3: Export Restrictions and Price Control (2010-present)
2010 export quotas: China implemented rare earth export quotas, officially for "environmental protection." Effect: Reduced global supply, prices spiked.
2010 Japan incident: Territorial dispute over Senkaku/Diaoyu islands. China allegedly restricted rare earth exports to Japan (unofficial embargo). Rare earth prices spiked 10x, Japanese manufacturers panicked.
WTO dispute (2014): US, EU, Japan sued China at WTO over export restrictions. China lost, had to remove formal quotas. But informal control remains (production quotas, consolidation of industry into state-owned enterprises).
Current situation (2026): China controls supply through production quotas (limiting how much Chinese companies can produce), consolidation (merging rare earth producers into fewer, state-controlled entities), and processing monopoly (even non-Chinese rare earths often get processed in China).
The Mountain Pass Story: US Rare Earth Rise and Fall
Mountain Pass mine (California) is a case study in how the US lost rare earth dominance—and is struggling to regain it.
The Rise (1950s-1990s)
Discovered: 1949, Mojave Desert, California
Peak production: 1990s, Mountain Pass produced 70%+ of global rare earths. The US dominated rare earth supply.
Applications: Color TVs (europium for red phosphor), magnets, catalysts. Mountain Pass was strategic US asset.
The Fall (1990s-2002)
Chinese competition: China undercut prices. Mountain Pass struggled to compete.
Environmental issues: 1998, wastewater spill (radioactive, contaminated area). Lawsuits, regulatory scrutiny, cleanup costs.
Closure: 2002, Molycorp (operator) shut down Mountain Pass. US rare earth production dropped to near-zero.
The Attempted Comeback (2010-present)
2010 wake-up call: China's export restrictions, Japan incident made US realize rare earth dependency was strategic vulnerability.
Molycorp revival (2010-2015): Molycorp reopened Mountain Pass, raised $1+ billion, planned full vertical integration (mining → processing → magnets). Stock price soared.
Bankruptcy (2015): Rare earth prices crashed (China increased supply after WTO ruling). Molycorp couldn't compete, debt-laden, filed bankruptcy.
MP Materials (2017-present): MP Materials bought Mountain Pass, restarted mining. Currently:
- Mining: 15% of global rare earth production
- Processing: Ships concentrate to China for processing (!!)
- Magnet manufacturing: Building US magnet facility (2025, not yet operational at scale)
The irony: US mine produces rare earths → ships to China for processing → buys back processed materials. Still dependent on China for the critical step.
Processing Is the Chokepoint (And It's Toxic)
Mining rare earths is straightforward (dig ore, crush, beneficiate). Processing—separating individual elements from mixed ore—is the hard part.
Why Processing Is Difficult
Chemical similarity: Rare earth elements are chemically nearly identical (all in same periodic table group). Separating them requires:
- Multiple solvent extraction stages (10-30 stages)
- Precise chemical control (temperature, pH, concentrations)
- Enormous volumes of chemicals (acids, solvents)
Environmental impact:
- Radioactive waste: Thorium and uranium co-occur with rare earths. Processing produces radioactive tailings.
- Toxic chemicals: Acids (sulfuric, hydrochloric, nitric), ammonia, solvents
- Water pollution: Tailings ponds leak, contaminate groundwater
- Air pollution: Dust, chemical fumes
Why China Dominates Processing
1. Accepted environmental costs: Chinese rare earth processing (especially in Inner Mongolia, Jiangxi province) created environmental disasters—polluted rivers, radioactive waste, destroyed farmland. China prioritized industrial capacity over environmental protection.
2. Built massive scale: Baotou (Inner Mongolia) is the global rare earth processing hub. Economies of scale make Chinese processing 30-50% cheaper than potential Western competitors.
3. Subsidies and state support: Chinese government supported rare earth industry through cheap land, energy, loans, environmental regulation exemptions.
Western countries: Environmental regulations make rare earth processing expensive and politically difficult (NIMBY opposition). No one wants a rare earth processing facility nearby (toxic, radioactive waste).
1. MINING (China: 70%, but alternatives exist)
• US (Mountain Pass): 15%
• Australia: 6%
• Others: 9%
• Chokepoint severity: MEDIUM (non-China sources available, could expand)
2. PROCESSING/REFINING (China: 85-90%)
• This is THE chokepoint
• Even US/Australian ore often processed in China
• Alternative processing: Lynas (Malaysia) = 5%, tiny others
• Building new processing: 5-10 years, $billions, environmental/political hurdles
• Chokepoint severity: EXTREME
3. SEPARATION/PURIFICATION (China: 90%+)
• Converting mixed rare earth oxides → individual pure elements
• Requires sophisticated chemical engineering
• China has 30+ years experience, rest of world rebuilding from zero
• Chokepoint severity: EXTREME
4. MAGNET MANUFACTURING (China: 90%+)
• Sintered neodymium-iron-boron (NdFeB) magnets
• China dominates production capacity
• Some Japanese production (5%), minimal elsewhere
• Chokepoint severity: EXTREME
5. MAGNET SUPPLY FOR WIND/EV (China: 85%+)
• Final products (wind turbine generators, EV motors) use Chinese magnets
• Even Western wind turbines, EVs often contain Chinese rare earth magnets
• Alternative suppliers emerging but tiny share
CONCLUSION:
Every chokepoint except mining is dominated by China (85-90%).
Processing is the critical bottleneck—can't make magnets without it.
Building alternative supply chain: 5-10 years MINIMUM.
Military Implications: Pentagon's Rare Earth Dependency
The Department of Defense depends on rare earths for virtually every advanced weapons system. And the supply comes from—or through—China.
What Military Systems Need Rare Earths
Aircraft:
- F-35: 417 kg rare earths (magnets, electronics, avionics)
- F-22: Similar amounts
- V-22 Osprey: Actuators, engines use rare earth magnets
- All modern military aircraft: Samarium-cobalt magnets (high-temperature stability)
Missiles and munitions:
- Tomahawk cruise missiles: Guidance systems
- JDAM (precision-guided bombs): Actuators, guidance
- Patriot missiles: Guidance, sensors
- All precision munitions depend on rare earth magnets + electronics
Naval systems:
- Aegis radar systems: Electronics, signal processing
- Submarine sonar: Rare earth magnets
- Electric ship propulsion: Permanent magnet motors
Space and satellites:
- GPS satellites: Electronics, solar panels
- Spy satellites: Sensors, optics (lanthanum lenses)
- Communication satellites: Electronics
The Pentagon's Problem
Stockpiles exist but limited: Department of Defense maintains strategic rare earth stockpiles (classified amounts). Estimates: months of supply at wartime production rates, not years.
Supply chain dependency:
- Rare earth magnets for military systems often sourced from China or companies using Chinese rare earths
- Alternative suppliers (Japan, limited US capacity) insufficient for wartime surge production
- If China embargoes rare earths, US military production of advanced weapons could halt within months
Pentagon initiatives to reduce dependency:
- Defense Production Act (DPA) funding: $billions for domestic rare earth processing, magnet manufacturing
- MP Materials contracts: Funding Mountain Pass expansion, processing facility, magnet plant
- Lynas partnership: Australian company building US rare earth processing plant (Texas, government-funded)
Timeline problem: These facilities won't be fully operational until 2027-2030. Meanwhile, China could cut supply anytime.

See how many components contain rare earths.
Nearly every electronic device in your life depends on them.
GLOBAL RARE EARTH MARKET:
• Rare earth oxides: $8-10 billion/year
• Rare earth magnets: $15+ billion/year
• Total rare earth value chain: $25-30 billion/year
CHINESE COMPANIES (Dominate market):
• China Northern Rare Earth Group: Largest producer
• China Minmetals: State-owned, major processor
• Shenghe Resources: Leading separation/purification
• Combined Chinese rare earth revenue: $20B+ (70%+ of global market)
WESTERN COMPANIES (Struggling to compete):
• MP Materials (US): Revenue $300M+ (mining only, ships to China for processing)
• Lynas Rare Earths (Australia): Revenue $500M+ (only non-Chinese processor at scale)
• Iluka Resources (Australia): Developing rare earth projects
• Combined Western revenue: <$2B (less than 10% of market)
PRICING POWER:
China can manipulate rare earth prices through export quotas, production limits.
2010-2011: Prices spiked 5-10x during export restrictions.
2015-2020: Prices crashed (China increased supply to kill competition like Molycorp).
2021-present: Prices rising again (demand surge from EVs, wind turbines).
INVESTMENT IN ALTERNATIVES:
• US DoD funding: $hundreds of millions (DPA funding for domestic supply)
• Private investment: $2-3 billion (MP Materials, Lynas, others)
• Still insufficient—China invested $tens of billions over 30 years
THE ECONOMICS:
Chinese companies profit from 70%+ market control.
Western companies can't compete on cost (Chinese processing 30-50% cheaper).
Alternative supply chains won't be economically viable without subsidies.
Historical Parallel: OPEC Oil Embargo (1973)
THE TRIGGER:
Yom Kippur War (October 1973): Arab states attack Israel. US supports Israel militarily. OPEC (Arab oil producers) retaliates with oil embargo against US, allies.
THE IMPACT:
• Oil prices quadrupled (from $3 to $12 per barrel)
• Gas shortages, rationing, long lines at pumps
• US economy contracted (recession 1973-1975)
• Inflation spiked (oil price shock rippled through economy)
• Strategic wake-up call: US vulnerable to foreign energy control
US RESPONSE:
• Strategic Petroleum Reserve created (emergency oil stockpile)
• Fuel efficiency standards (CAFE standards for cars)
• Investment in domestic energy (Alaska pipeline, offshore drilling)
• Diversification of oil suppliers (reduce Middle East dependency)
THE LESSON:
Control of critical resources = geopolitical weapon.
OPEC used oil to punish US foreign policy.
Economic impact lasted years.
RARE EARTH PARALLEL (2010 & potential future):
• China restricted rare earth exports to Japan (2010)
• Prices spiked 10x, Japanese manufacturers scrambled
• Demonstrated China's willingness to weaponize rare earth supply
POTENTIAL FUTURE EMBARGO:
If US-China conflict (Taiwan, trade war escalation):
• China could embargo rare earths to US, allies
• Wind turbine, EV production halts (no magnets)
• Military production crippled (jets, missiles need rare earths)
• Electronics supply chains disrupted
• Strategic Rare Earth Reserve exists but months of supply, not years
Same playbook as OPEC 1973.
Rare earths are the new oil for geopolitical leverage.
The Alternative Scenario: China Restricts Rare Earth Exports
TRIGGER:
Major US-China conflict over Taiwan. China implements comprehensive rare earth export restrictions to "unfriendly nations" (US, allies supporting Taiwan).
MONTH 1: IMMEDIATE SUPPLY SHOCK:
• Rare earth magnet supply to US/EU drops 80%+
• Wind turbine production halts (no magnets for generators)
• EV production drops 60-70% (permanent magnet motors unavailable)
• Electronics manufacturers scramble for inventory
• Prices spike 5-10x for remaining supply
MONTH 3: CASCADE EFFECTS:
• Renewable energy installations stall (no wind turbines)
• EV adoption collapses (production limited, prices surge)
• Consumer electronics shortages (phones, laptops, headphones)
• Climate targets unreachable (renewable deployment halted)
MONTH 6: MILITARY IMPACT:
• Pentagon burns through rare earth stockpiles
• F-35 production slows (limited rare earth magnets)
• Precision munitions production constrained
• Satellite launches delayed (component shortages)
• US military readiness degraded
YEAR 1: SCRAMBLE TO REBUILD:
• MP Materials, Lynas fast-tracked (billions in emergency funding)
• Processing facilities rushed to completion
• But: Building processing capacity takes 3-5 years minimum
• Substitution efforts (induction motors for EVs, alternative magnet materials) only partially successful
• Japan, Korea share limited non-Chinese supply with US (insufficient)
YEAR 2-3: PARTIAL RECOVERY:
• Some US/Australian processing comes online (limited capacity)
• Rare earth supply reaches 30-40% of pre-embargo levels
• Wind turbine, EV production recovering but constrained
• Prices stabilize at 2-3x pre-embargo levels
• Military production adapts but less capable systems (non-rare-earth alternatives)
YEAR 5-7: NEW EQUILIBRIUM:
• Western rare earth supply chain operational but smaller scale, higher cost
• Renewable energy deployment permanently slower
• EV adoption delayed 5-10 years
• Total economic cost: $hundreds of billions (slower energy transition, higher costs, lost manufacturing)
• Strategic lesson learned (too late): Rare earth dependency was critical vulnerability
THE LESSON:
China demonstrated willingness to use rare earths as weapon (2010 Japan incident).
Full embargo would devastate Western manufacturing, military, energy transition.
Alternative supply chains exist but insufficient and take decade to scale.
Rare earth monopoly = strategic leverage.
Conclusion: The Ultimate Supply Chain Chokepoint
The rare earth monopoly reveals the most concentrated supply chain vulnerability in the energy transition and modern technology.
China doesn't just dominate—they control 80-90% of processing, the critical chokepoint that converts mined rare earths into usable materials for magnets, electronics, catalysts.
Every wind turbine (200-600 kg rare earth magnets), every EV motor (1-2 kg magnets), every smartphone (10+ rare earth elements), every F-35 fighter jet (417 kg rare earths), every precision missile depends on rare earth supply.
And China controls that supply through:
- 30+ years of investment while West shut down production
- Accepting environmental costs (toxic processing, radioactive waste)
- Massive scale (85-90% of global processing capacity)
- Willingness to weaponize supply (2010 Japan incident proved this)
The US is trying to rebuild rare earth supply chains:
- MP Materials (Mountain Pass mining, building processing)
- Lynas (Australian company, US processing plant funded by Pentagon)
- DoD funding ($hundreds of millions through Defense Production Act)
But these won't be fully operational until 2027-2030, and even then won't match Chinese capacity or cost.
The pattern across energy infrastructure is consistent:
- Solar: China 80% of panels, owns supply chain (Part 1)
- Batteries: China 70% of cells, controls material processing (Part 2)
- Grid: China builds UHV networks, US grid crumbling (Part 3)
- Rare earths: China 80-90% of processing, ultimate chokepoint (Part 4)
Every layer of energy transition infrastructure runs through China. Rare earths might be the most concentrated and strategically critical of all.
Because you can't build wind turbines, EVs, or advanced weapons systems without them. And China controls the supply.
