In May 2025, Ford Motor Company temporarily halted production of its Explorer SUV at its Chicago Assembly Plant. Not because of a labour dispute. Not because of falling demand. Because it had run out of a specific type of rare earth magnet, produced almost exclusively in China, and without which the vehicle's electric power steering system cannot function. The magnet in question — a neodymium-iron-boron permanent magnet roughly the size of a deck of cards — contains two elements, dysprosium and terbium, for which China holds what amounts to a total global monopoly on separation capacity. Beijing had restricted exports of these seven critical elements in April 2025, in direct retaliation for U.S. tariffs. Ford's Chicago plant is not a niche facility. It produces one of America's best-selling vehicles. It stopped because a decision made in a Beijing government ministry had severed a supply chain link that nobody in Detroit had bothered to build a backup for. This is what it looks like when the periodic table becomes a geopolitical weapon. Not a declaration of war. A licensing requirement. And a factory that goes quiet.
The Invisible Empire — Part 4
Politics of the Periodic Table: How China Turned Chemistry Into Geopolitical Power
The Mine That Runs the Modern World — Bayan Obo, Inner Mongolia
Bayan Obo Rare Earth Mine, Inner Mongolia — The World's Largest Single Source of Rare Earth Elements
China extracted approximately 270,000 tonnes of rare earth oxide equivalent in 2024 — six times the U.S. output of 45,000 tonnes. Bayan Obo in Inner Mongolia produces the majority of this supply. The environmental cost has been severe: groundwater contamination, radioactive element release, and heavy metal pollution across surrounding communities. The West effectively outsourced this environmental burden to China while retaining the economic benefits of cheap rare earth inputs — a geopolitical bargain whose strategic cost is now becoming apparent.
What Rare Earth Elements Actually Are — and Why They Are Neither Rare Nor Simple
The name is a double misnomer. Rare earth elements — the 17 metallic elements comprising the 15 lanthanides plus scandium and yttrium — are not particularly rare in geological terms. Cerium, the most abundant of them, is more common in the earth's crust than copper. The China-US Focus analysis put it plainly: they are "rare" not because of scarcity but because they occur co-mingled in sediment rock deposits alongside many other minerals, often radioactive ones, and the processes required to mine them, separate them from each other, and refine them into usable form are extraordinarily complex, environmentally damaging, and capital-intensive.
Each element in the rare earth group has unique magnetic, optical, or electronic properties that make it indispensable for specific applications. Neodymium and praseodymium produce the strongest permanent magnets known — the neodymium-iron-boron magnets that drive the electric motors in every EV, the generators in every wind turbine, the actuators in F-35 jet fighters, and the servo motors in industrial robots. Dysprosium and terbium enhance these magnets' ability to operate at high temperatures without losing their magnetic properties — which is why they appear in Tesla's humanoid robots, Virginia-class submarine components, and the power steering systems of ordinary family cars. Europium and terbium produce the red and green phosphors in LED screens and energy-efficient lighting. Lanthanum is essential to nickel-metal hydride batteries and petroleum refining catalysts. Cerium is the abrasive used to polish the silicon wafers on which semiconductor chips are manufactured.
None of these applications can currently be substituted at scale. Rare earth magnets produce the best performance of any magnet type. Until alternative technologies can be commercially scaled — and several are in development, but none have yet reached the cost-performance threshold required — the global economy remains structurally dependent on a set of 17 elements whose processing capacity is concentrated in one country to a degree that has no parallel in any other industrial input.
How China Built Its Monopoly: The Forty-Year Strategy
China's dominance in rare earths was not an accident of geology, though geology helped. China holds an estimated 44 per cent of global rare earth reserves — followed by Vietnam at 22 per cent, Brazil and Russia at roughly 21 per cent each, India at 6.9 per cent, and Australia at 5.7 per cent. But as the World Financial Review analysis noted in September 2025, China's real power lies not in its reserves but in its processing capacity. China controls nearly 90 per cent of global refining capacity — including material mined elsewhere, in Australia, Myanmar, and Vietnam. The monopoly is a manufacturing monopoly, not a geological one.
Deng Xiaoping reportedly said in 1992, visiting Inner Mongolia: "The Middle East has oil; China has rare earths." The observation was not boastful. It was a statement of strategic intent. Beijing began investing in the complete rare earth supply chain in the 1980s — mining, chemical separation, magnet manufacturing, recycling, and alloy technology — with a patience and coordination that no Western government applied to any comparable industrial resource during the same period.
The mechanism was straightforward. China accepted the environmental costs of rare earth processing that Western countries refused to absorb. The U.S. had operated the Mountain Pass rare earth mine in California as the world's dominant supplier through the 1970s and into the 1980s. Then environmental regulations tightened, processing costs rose, and Chinese production — subsidised by state capital, operating with far looser environmental standards, and priced to undercut any Western competitor — made Mountain Pass commercially unviable. The mine closed definitively in 2002. The CEPA analysis of January 2026 stated the situation plainly: China attained its dominance not only through geology but through a long-term strategic investment, paired with a willingness to absorb environmental costs that Western democratic governments could not politically impose on their own populations.
A bipartisan Congressional probe released in November 2025 documented Beijing's playbook in granular detail. It hands tens of billions of dollars in zero-interest-rate loans to state mining firms. It built a legal framework for controlling mineral prices. And whenever Western competitors attempted to re-enter the market, China flooded global markets with cheap product to drive them out. The CEPA analysis confirms this pattern: every time competition appeared on the horizon, China dumped product to put the competition out of business. The result is a monopoly maintained not just by industrial capability but by predatory pricing strategy backed by state subsidy — a combination that private-sector Western firms operating on commercial returns simply cannot compete against.
October 2025: When the Weapon Was Deployed in Full
China's willingness to use its rare earth position as a foreign policy instrument had been demonstrated before — most notably in 2010, when it restricted rare earth exports to Japan during a maritime dispute over the Senkaku Islands. Japan's industrial sector, heavily dependent on rare earth inputs for its electronics and automotive industries, responded by diversifying supply chains and investing in rare earth recycling with a seriousness that no other country matched. The lesson was absorbed in Tokyo. It was largely ignored in Washington and Brussels.
In April 2025, following President Trump's announcement of sweeping reciprocal tariffs on Chinese goods, Beijing retaliated by imposing export controls on seven heavy rare earth elements: dysprosium, gadolinium, lutetium, samarium, scandium, terbium, and yttrium. The effect was immediate. Rare earth magnet shipments from China halved in May 2025, according to Reuters data cited by GQG Partners. Ford halted Explorer production in Chicago. Multiple defence contractors contacted the Pentagon about supply chain disruptions to components requiring dysprosium and terbium. U.S. wind turbine manufacturers reported lead time extensions for magnetic components of six to twelve months.
In October 2025, China escalated further. It expanded its export control regime by adding five more rare earths — erbium, europium, holmium, thulium, and ytterbium — and extended controls to cover related processing technologies, equipment, and, crucially, any foreign-produced items that incorporated rare earths of Chinese origin. This last provision was, according to the CFR analysis of February 2026, a "partial foreign-direct-product rule" — the same jurisdictional mechanism the U.S. had used against Huawei, now turned by China against Western manufacturers. Any foreign firm using Chinese rare earth inputs anywhere in its supply chain required a Chinese export licence. The rule reached into supply chains in Germany, Japan, South Korea, and the United States simultaneously.
The IEA noted that in 2024, China exported 58,000 tonnes of rare earth magnets — enough to manufacture components for millions of cars, industrial motors, or aircraft, or to build thousands of strategic military systems, data centres, and wind turbines. Restricting that export flow did not merely inconvenience consumer electronics companies. It threatened the physical manufacturing capacity of the green energy transition, the defence industrial base of NATO, and the AI data centre build-out that every major Western technology company was simultaneously attempting to accelerate. The tensions were partially eased by the Kuala Lumpur Accord of late May 2025, in which both sides agreed to suspend fresh restrictions for one year. But the accord resolved nothing structurally. It was a ceasefire, not a peace treaty. The rare earth weapon remained loaded.
The Supply Chain That Runs From a Salt Flat to Your Electric Car
Salar de Uyuni, Bolivia — The World's Largest Lithium Reserve, Currently the Prize in a U.S.-China Resource War
Bolivia's Salar de Uyuni contains an estimated 21 million tonnes of lithium — the largest single deposit on earth. In late 2024, Bolivia signed a $1 billion agreement with a Chinese-led consortium including CATL to build direct lithium extraction plants on the site. The Lithium Triangle — Bolivia, Chile, and Argentina — holds approximately 49.6% of global lithium resources. China already processes 60–70% of global lithium and produces roughly 75% of the world's battery cells, making it the dominant force both above and below ground in the green energy supply chain.
Lithium: The White Gold Underneath the Desert
If rare earth elements are the sinew of the green energy transition — the magnets in motors, the phosphors in lights, the catalysts in refineries — then lithium is its blood. Every lithium-ion battery in every electric vehicle, every grid-scale energy storage system, every smartphone, and every laptop runs on lithium chemistry. There is no commercially viable substitute at current technology levels. And the geography of lithium reserves, like the geography of rare earth processing, is extraordinarily concentrated.
The Lithium Triangle — Argentina, Bolivia, and Chile — holds approximately 49.6 per cent of global lithium resources, according to the U.S. Geological Survey's 2025 data. Bolivia alone possesses an estimated 21 million tonnes of lithium in its Salar de Uyuni salt flat — the largest single deposit on earth. Argentina holds 19.3 million tonnes. Chile, at 9.6 million tonnes, is the smaller of the three in reserves but by far the most productive, accounting for approximately 24 per cent of global lithium carbonate equivalent production in 2023, making it the world's second-largest producer behind Australia.
But the geography of lithium reserves does not determine the geography of lithium power. As with rare earths, the strategic leverage lies downstream — in processing and manufacturing. China processes approximately 60 to 70 per cent of global lithium, produces about 75 per cent of global battery cells, and controls the majority of anode and cathode output. Chinese firms CATL and BYD dominate global battery manufacturing, with CATL alone holding roughly 38 per cent of global market share and BYD approximately 17 per cent. Even lithium extracted in Australia, Argentina, and Chile is overwhelmingly shipped to China for processing before it can be used in any battery anywhere in the world. The ScienceDirect analysis noted that in 2023, the vast majority of semi-processed lithium carbonate from Chile and Argentina went directly to China, South Korea, and Japan — with China as the dominant destination.
This creates an almost perfect replication of the rare earth dynamic: other countries hold the raw material, China holds the industrial capacity to transform it into something useful, and the world pays whatever China charges for the transformation. The Lithium Triangle countries are geologically rich but industrially dependent. They extract the ore and export the value. China captures the margin at every downstream step.
Bolivia's Faustian Bargain and the Battle for Uyuni
Bolivia sits on the world's largest lithium deposit and has historically extracted the least of the three triangle countries — producing only about 950 tonnes of lithium carbonate equivalent in 2023, compared to Chile's 140,000 tonnes. This gap is not geological. It is political and infrastructural. Bolivia's socialist governments have, for two decades, insisted on a state-led industrialisation model: the country would process its own lithium domestically rather than exporting raw brine, building an integrated battery industry within Bolivia's borders. The aspiration is legitimate. The execution has been extremely difficult.
In late 2024, Bolivia signed a $1 billion agreement with a Chinese-led consortium — CBC, including CATL — to build direct lithium extraction plants at Uyuni, with the Bolivian state retaining a 51 per cent stake in each project. The National Interest analysis of February 2025 reported that Russia had simultaneously moved into Bolivia's Pastos Grandes salar through a deal with Uranium One, part of Rosatom. The arrangement concentrated two geopolitically hostile-to-Washington powers simultaneously in the region that holds the world's largest lithium reserves — a development that Catalyst's August 2025 analysis described as "largely under the radar of Bolivian and U.S. media."
The Bolivian population is not passive about these arrangements. In July 2025, a congressional session in La Paz descended into chaos — shouting, water-throwing, and protests — as lawmakers opposed deals with Chinese and Russian firms worth around $2 billion. The opposition was not ideological in a simple sense. It reflected a deep suspicion, widely held in Bolivia and across the Lithium Triangle, that foreign investment in lithium extraction, however structured on paper, would deliver the raw value to foreign processors and foreign shareholders rather than to the Bolivian communities living on and around the salt flats. This suspicion is historically well-founded. Latin America's experience with extractive industries over two centuries provides little basis for optimism that the arrangement will be different this time.
Chile and Argentina: Different Models, Same Dependency
Chile and Argentina have taken opposite political approaches to lithium development, and both approaches converge on the same structural problem. Chile, under President Gabriel Boric, declared lithium a strategic resource and in April 2025 announced that all new lithium contracts would operate as public-private partnerships, with the state mining firm Codelco taking a central role. BYD and Tsingshan had been selected in 2023 to build cathode and battery plants in Chile as part of an industrial upgrading strategy — but by 2025, both projects had been paused due to falling lithium prices and regulatory disagreements. The industrial upgrading strategy stalled precisely when its logic was most urgent.
Argentina, under libertarian President Javier Milei, took the opposite approach — largely deregulated provincial governance, investor-friendly policy, and minimal state coordination. Rio Tinto received approval for a $2.5 billion lithium project at Salta's Rincon salt flat in May 2025 under Argentina's new investment incentive regime. Argentina forecast a 75 per cent increase in production to 130,800 tonnes of lithium carbonate equivalent in 2025. The production numbers are climbing. The processing, however, still flows primarily to China.
The fundamental constraint of the Lithium Triangle's three divergent political strategies — state-led Bolivia, nationalist Chile, deregulated Argentina — is that none of them addresses the downstream processing gap. Extracting lithium brine from a salt flat is relatively straightforward compared to building the cathode manufacturing plants, battery cell gigafactories, and recycling infrastructure that capture the industrial value of the resource. The capital requirements for downstream investment are enormous. The technical expertise is concentrated in China, South Korea, and Japan. And falling lithium prices — a consequence partly of Chinese market manipulation, partly of global EV demand slowdown in 2024 — have made the economics of domestic processing less attractive precisely when the geopolitical case for it is most compelling.
The Green Energy Trap: How the Clean Energy Transition Built New Dependencies
There is a profound irony at the centre of the green energy transition's critical minerals politics. The world's democracies decided, for good reasons, to decarbonise their economies — to shift from fossil fuels to electric vehicles, wind turbines, solar panels, and battery storage. In doing so, they created a new set of strategic material dependencies that are, in several respects, more concentrated and harder to diversify than the oil dependencies they were escaping. At least OPEC had thirteen member states. The rare earth processing monopoly has one.
The IEA's Global Critical Minerals Outlook 2025 documented this starkly: for a remarkable 19 out of 20 important strategic minerals, China is the leading refiner, with an average market share of 70 per cent. China dominates midstream and downstream battery supply chains with shares of 80 per cent or more in many key areas. On 9 October 2025, China announced export controls specifically on lithium-ion battery supply chains — covering battery cells and packs, cathode precursors, anode materials, LFP cathode materials, and the equipment used to manufacture all of these. This was not merely restricting raw minerals. It was restricting the industrial capacity to build the batteries that the entire global clean energy transition depends upon.
The UNIDO projection cited by Chatham House's analysis provides the broader context: by 2030, China is projected to account for 45 per cent of global manufacturing value added, compared to 11 per cent for the United States, 5 per cent for Japan, and 3 per cent for Germany. The gap between Chinese manufacturing scale and Western manufacturing scale is not closing. On the metrics that matter most for the green energy transition — battery cells, cathode materials, EV components, solar panels, wind turbine magnets — it is widening. The Australian Strategic Policy Institute's research found that China leads the United States in 57 out of 64 critical technology categories. The green energy transition, designed in part to reduce geopolitical vulnerability to Russian gas and Middle Eastern oil, has created a comparable vulnerability to Chinese minerals and manufacturing — and in some ways a more severe one, because the concentration is higher and the alternatives are further from commercial viability.
Cobalt, Congo, and the Human Cost of the Clean Economy
No account of critical minerals geopolitics is complete without the Democratic Republic of Congo. The DRC holds approximately 70 per cent of global cobalt reserves — a mineral essential to the cathode chemistry of most lithium-ion battery types currently in commercial production. Cobalt stabilises battery cathodes, preventing thermal runaway and extending battery life. Every major EV manufacturer uses cobalt in some proportion of its battery chemistry. Tesla has worked to reduce its cobalt content, but elimination is not yet commercially viable across its full product range.
The cobalt supply chain from Congo is a documented human rights catastrophe. Artisanal mining — informal, unregulated hand mining — accounts for approximately 15 to 20 per cent of Congo's cobalt output and employs an estimated 150,000 to 200,000 people in conditions that include child labour, toxic mineral exposure, and collapse fatalities. Chinese companies control the majority of Congo's industrial cobalt mines through equity stakes, offtake agreements, and state-to-state deals with the Congolese government that have been negotiated over two decades of strategic investment in African extractive industries. By the time cobalt reaches a battery cell, its provenance is often effectively untraceable, layered through multiple intermediaries and processing steps that each time dilute the ability to audit supply chain conditions.
This is the underside of the clean energy transition's periodic table politics. The electric vehicles marketed in Europe and North America as the vehicle of a cleaner future are powered partly by minerals extracted under conditions that would be illegal in every country where those vehicles are sold. The consumers who buy them are not culpable in any simple sense — they cannot audit supply chains that billion-dollar corporations with full legal and investigative resources struggle to audit. But the structural dependency remains: the clean economy runs, in part, on extraction that is neither clean nor equitable.
The Battery That Powers the Clean Economy — and the Supply Chain Behind It
Inside a Battery Gigafactory — Where the Green Energy Transition Actually Gets Made
China produces approximately 75% of the world's battery cells and holds 80% or more of market share in most battery supply chain segments, according to the IEA's Global Critical Minerals Outlook 2025. CATL alone commands roughly 38% of global battery market share. In October 2025, China extended its export control regime to cover battery cells, cathode precursors, anode materials, and manufacturing equipment — effectively threatening to weaponize the entire industrial infrastructure of the global clean energy transition simultaneously.
The Western Response: Too Late, Too Slow, and Structurally Constrained
The United States, the European Union, Australia, Japan, and Canada have all recognised the critical minerals dependency problem and have all launched policy responses. The diagnosis is accurate. The treatment is, so far, insufficient to the scale of the challenge.
In the United States, the Mountain Pass mine in California resumed rare earth mining operations in 2017 under MP Materials, a company that took the facility out of bankruptcy. By 2024, Mountain Pass was extracting approximately 45,000 tonnes of rare earth oxide equivalent annually — about one-sixth of China's output. More significantly, the processing chain remains incomplete: advanced chemical separation and magnet production at Mountain Pass are not yet fully operational, and the Defense Department has committed funds to build a mine-to-magnet chain by 2027, but the CEPA analysis of January 2026 described that goal as "far from assured, especially for heavy rare earths such as dysprosium and terbium, where China has a near-total monopoly."
The EU's Critical Raw Materials Act, enacted in 2024, set ambitious targets: 10 per cent of annual consumption to be extracted domestically, 40 per cent to be processed domestically, and 25 per cent to be recycled domestically by 2030. These targets address the correct problem. Achieving them requires permitting reforms, capital commitments, and technical capacity that most EU member states have not yet operationalised. The EU imported 98 per cent of its rare earth supply from China in 2022. Getting from 98 per cent dependency to 60 per cent dependency in six years requires not just policy ambition but the physical construction of mines, separation plants, and magnet factories that take years to permit and years more to build.
Australia, which holds significant rare earth deposits and has been developing processing capacity at Lynas Rare Earths — currently the only significant rare earth producer and processor outside China at commercial scale — presents the most credible near-term alternative supply source for Western countries. Lynas operates a separation and processing facility in Malaysia, which has itself become a political flashpoint as the Malaysian government has periodically questioned the facility's operating licence on environmental grounds. The geopolitics of rare earth diversification reach into Southeast Asian domestic politics in ways that complicate straightforward supply chain restructuring.
China, meanwhile, is not standing still while its competitors attempt to diversify. It is rapidly expanding into the recovery and recycling spaces — establishing China Resources Recycling Group Ltd. in 2024, a state-owned enterprise tasked with scaling recovery of end-of-life batteries, scrap steel, and electronic waste. The IEA noted that China plans to recycle battery and other e-waste and refine 75 per cent of global battery materials by 2030. If this target is achieved, China will control not only the primary supply chain for battery materials but the secondary supply chain through recycling — potentially locking in its dominance even as primary deposit diversification proceeds.
The Geopolitical Structure: What the Periodic Table Tells You About Power
Step back from the individual mineral stories — rare earths, lithium, cobalt — and a coherent geopolitical structure emerges. It has the same shape in every case. A critical material with no short-term substitute, essential to both the clean energy economy and the defence industrial base, is concentrated in processing capacity in a single country that has demonstrated willingness to weaponise that concentration. The Western democracies spent three or four decades optimising their supply chains for cost efficiency and outsourcing the environmentally difficult parts of the production process to countries with lower regulatory standards and lower labour costs. China absorbed those outsourced processes, built industrial scale around them, captured the margin, and then discovered — as any strategist would have predicted — that industrial monopolies over essential inputs are instruments of geopolitical leverage.
The CFR put it directly in its February 2026 analysis: "China's weaponization of critical minerals began under President Biden and continued in President Trump's second term." It is bipartisan in the sense that it has proven resistant to the political preferences of any single U.S. administration. It is structural, not episodic. The export control escalation of 2023 to 2025 — gallium and germanium first, then rare earths, then battery supply chains — follows the same escalatory logic as the semiconductor technology war described in Part 2 of this series. Each step tightens the screws on a different segment of the supply chain. Each step reveals another dependency that nobody in Washington or Brussels had built a redundant supply for.
What makes this particular pillar of invisible empire distinctively durable is its intersection with the green energy transition — an objective that every major Western democracy has committed to as both climate policy and economic strategy. Decarbonising the economy requires more of the very minerals over which China has built strategic dominance. The harder the West pushes for clean energy at scale, the more it accelerates its demand for lithium, rare earth magnets, cobalt, and battery materials — and the more leverage it concentrates in the hands of the country that processes and manufactures those things. The clean energy transition, as currently structured, is partially a transfer of strategic dependency from petrostates to China. Whether that transfer represents an improvement in the West's geopolitical position depends on assumptions about Chinese behaviour that the events of 2025 have comprehensively called into question.
Deng Xiaoping was right. The Middle East had oil. China has rare earths. And unlike oil — which burns, which can be substituted over time, which flows from many sources — the monopoly on processing rare earth elements does not deplete with use. It deepens with every electric car manufactured, every wind turbine installed, every data centre built, and every fighter jet that requires a permanent magnet actuator to fly. The periodic table is not changing. The question is who controls access to the elements that make the modern world run — and what price they choose to charge for that control.
