At their June 2026 summit in Évian-les-Bains, G7 leaders formally expanded the International Energy Agency's mandate to encompass critical minerals supply security, modelling the new framework on the oil-crisis emergency stock system built in 1974. With China refining 70 percent of 19 out of 20 strategic minerals and European rare earth prices running at up to six times Chinese domestic levels, the urgency is real. Whether the architecture can match it is a harder question.
Introduction
The town of Évian-les-Bains sits on the southern shore of Lake Geneva, its Belle Époque hotels stacked against forested slopes that rise toward the Swiss border. It is a place associated with bottled water and quiet diplomacy, which made it an appropriate setting, on June 17, 2026, for an agreement that was simultaneously dramatic in its ambition and cautious in its obligations. G7 leaders, gathered for the final day of France's summit presidency, signed a declaration on critical minerals supply chains that civil servants on both sides of the Atlantic had spent months drafting, arguing over, and redrafting. The finished document ran to several thousand words. Its most consequential sentence was also its most understated: a commitment to establish a joint cooperation mechanism, with the help of the International Energy Agency, to share data and alerts on future market stress or supply disruption.
For those familiar with the IEA's institutional history, the phrasing carried a specific resonance. The agency was created in 1974, in the aftermath of the Saudi oil embargo, precisely to build the kind of collective early-warning and coordinated-response machinery that no individual country could sustain alone. The founding insight was simple: concentrated supply in the hands of a single producer group, combined with the absence of any coordinated consumer response, is a geopolitical vulnerability dressed up as an energy market. What the G7 has now concluded, five decades later, is that the same logic applies to lithium, dysprosium, graphite, and cobalt. The difference is that this time, the concentrated supplier is not a cartel of oil exporters. It is a single country.
The numbers that hang over the Évian declaration are not abstract. The IEA's Global Critical Minerals Outlook 2025 found that, for 19 out of 20 strategic minerals, China is the leading refiner, with an average market share of 70 percent. For gallium, graphite, manganese, and rare earths, that share climbs above 90 percent. European rare earth prices, following China's April 2025 export control wave, reached up to six times Chinese domestic levels. The IEA's executive director, Fatih Birol, writing in Time magazine in March 2026, was direct: "It is not right to depend on one country. The golden rule of energy security is diversification." What the G7 has now tried to do, in Évian, is institutionalise that principle. The harder work is proving it can actually be done.
How the Crisis Was Built, and How Fast It Arrived
The escalation that gave the Évian summit its sense of urgency did not happen overnight, but it accelerated with a speed that caught many Western policymakers off guard. In December 2024, China restricted exports of gallium, germanium, and antimony to the United States. Early 2025 brought further controls on tungsten, tellurium, bismuth, indium, and molybdenum. Then, on April 4, 2025, Beijing announced export controls on seven heavy rare earth elements, along with all related compounds, metals, and magnets, a move that sent immediate shockwaves through automotive and defense supply chains on three continents.
The human-scale consequences arrived quickly. Carmakers in the United States, Europe, and Japan found themselves unable to obtain the permanent magnets that their electric motors require. Some cut utilization rates at assembly plants. Others temporarily shut production lines. The disruption was not total, but it was sufficient to demonstrate how little buffer existed between Chinese export licensing decisions and factory floors in Stuttgart, Nagoya, and Detroit. Even after trade volumes partially recovered, the price signals persisted. European rare earth prices settled at levels that, in some categories, were running at up to six times the price that Chinese manufacturers were paying domestically, a structural cost disadvantage with no near-term remedy.
Beijing did not stop there. By October 2025, China had announced major export controls on lithium-ion battery supply chains, covering a broad range of battery materials, technologies, and equipment. In November, it suspended certain rare earth equipment controls through November 2026, a move analysts described as pressure calibration: signalling flexibility while preserving the core architecture of the control regime. Then, in April 2026, China issued the Regulations on Countering Improper Extraterritorial Jurisdiction by Foreign States, expanding its retaliatory toolkit with immediate effect and no transition period. The cumulative picture was one of a graduated, sustained campaign to demonstrate that supply chain leverage is a policy instrument, not merely a market condition.
The IEA's broader analysis captures just how structurally entrenched this dominance has become. Between 2020 and 2024, growth in refined material production was heavily concentrated among leading suppliers, and the geographic concentration of refining actually increased across nearly all critical minerals. Some 90 percent of supply growth during that period came from the top single supplier for the relevant commodity: Indonesia for nickel, China for cobalt, graphite, and rare earths. More than half of a broader group of energy-related minerals are now subject to some form of export control, and those restrictions are expanding in scope to cover not just raw materials but processing technologies, including those for lithium and rare earth refining. The G7's sense that this is a structural emergency, not a cyclical disruption, is not misplaced.
The IEA's New Assignment, and the 1974 Model It Is Being Asked to Replicate
When G7 leaders agreed at Évian to embed the IEA at the centre of their critical minerals response, they were explicitly invoking a historical template. The IEA was established by 16 nations in November 1974, at the instigation of the United States, specifically because the 1973-74 Saudi oil embargo had demonstrated that market-economy countries, acting individually, were structurally vulnerable to supply concentration. The founding framework required each member country to hold oil stocks equivalent to at least 90 days of net imports and to participate in coordinated release mechanisms during severe supply disruptions. The premise was that the credible threat of a collective response changes producer behaviour even when no release is triggered. Stocks, in other words, function as a deterrent as much as a remedy.
The Évian declaration applies this logic to minerals. G7 leaders acknowledged the essential role that stockpiling can play in improving the security of supply and market stability. They committed to developing and increasing domestic stockpiling capacities in both the industrial and public sectors. They agreed to exchange information on stockpiling systems, best practices, procurement mechanisms, and release protocols, specifically through the IEA Critical Minerals Security Programme and the Japanese Organisation for Metals and Energy Security (JOGMEC), which has maintained a national stockpile of strategic metals since the 1980s and represents perhaps the most developed model among G7 members. Lithium and nickel were designated as the two pilot metals for the new coordination framework, with an ambition to extend the pilot to five new critical minerals each year.
The IEA had been preparing for this assignment for some time. In January 2026, it published a detailed Critical Minerals Stockpiling Assessment Framework, authored by analysts including Alessio Scanziani, Shobhan Dhir, and Tae-Yoon Kim, that examined supply risk, alternative supply availability, strategic importance, and the feasibility of stockpiling across multiple minerals. In late 2024, it had already conducted a first-of-its-kind emergency preparedness exercise with governments as part of its expanding Critical Minerals Security Programme. In May 2026, just weeks before the summit, it convened a technical workshop in Brussels with government representatives from the United States, Germany, France, Canada, Italy, Spain, and the European Commission, alongside private sector participants including General Motors, Glencore, Umicore, and Leonardo, to examine the technical architecture of stockpiling systems and understand industry perspectives.
Birol has been consistent in framing the mineral challenge in terms that deliberately echo the oil security mandate. The IEA, he wrote in March, has "built up a new Critical Minerals Security Programme to promote coordinated action in the face of supply disruptions. As with oil markets in the 1970s, the challenges are significant. Markets alone won't deliver greater diversity. We need new policies and new international partnerships between resource-rich countries, refiners, capital providers, and consumers." The analogy is not decorative. The agency is consciously positioning the new programme as a structural equivalent to the oil emergency system, one that will maintain technical capacity and coordinated response protocols between crises, not only during them. As one analysis circulating among G7 delegations noted, the strategic petroleum reserve framework under the IEA functions precisely because a permanent institution maintains trigger protocols and release mechanisms continuously. The architecture has to exist before it is needed.
The Legitimacy Battle: Beijing's Counter-Narrative and What It Reveals
China's response to the Évian declaration arrived within hours of its publication. At his regular press conference on June 18, 2026, Foreign Ministry Spokesperson Lin Jian stated that China's "standardization and refinement of its export control system is consistent with international practice" and urged the G7 to "earnestly observe the principles of market economy and international trade rules, and stop disrupting the international trade order with the self-made rules of a small group." The phrasing was deliberate. Beijing was not merely defending its export controls on their merits. It was contesting the G7's authority to set the terms of the debate.
This framing strategy has been consistent throughout the escalation. China's position is that its export controls are legitimate regulatory instruments, no different in kind from those maintained by the United States, the European Union, or any other major economy. The comparison Beijing draws most pointedly is with the US Foreign Direct Product Rule, which Washington has used to restrict foreign-manufactured semiconductor products incorporating American-origin technology. China's April 2026 extraterritorial rare earth control mechanism, which requires export licenses for products manufactured outside China whose components contain Chinese-origin rare earths above a 0.1 percent concentration threshold, is explicitly modelled on that architecture. The message is: if Washington can apply extraterritorial controls to semiconductors, Beijing can apply the same logic to minerals.
Chinese analysts amplified this line in the days following the summit. Cui Hongjian, director of European Studies at the China Institute of International Studies, told the Global Times that it is "irrational for certain G7 countries to put pressure on China under US influence," and suggested other G7 members should exercise independent judgment rather than follow Washington's lead. Xin Qiang, deputy director of the Center for American Studies at Fudan University, argued that China holds dominant positions in the rare earth industry in terms of products, technology, costs, and industry standards, and that "group confrontation for political purposes to challenge the existing structure will unlikely succeed."
The legitimacy contest matters because it shapes the diplomatic environment in which G7 supply-chain diversification has to operate. Resource-rich countries in Africa, Latin America, and Southeast Asia are watching the framing battle carefully. Many of them have economic relationships with China that predated, and run deeper than, their engagement with Western critical minerals initiatives. The G7 declaration's language, which describes China's export controls as "arbitrary" and accuses unnamed parties of "economic coercion," uses a vocabulary of trade-order violation that resonates with Washington and Brussels but carries less force in capitals where Chinese investment in mining and processing infrastructure has been the most visible external commitment of the past two decades. Building the investment pipeline that supply diversification requires will demand not just money but diplomatic credibility in precisely those capitals.
The Fractures Within: Secretariat, Sequencing, and the Gap Between Ambition and Architecture
The Évian declaration presented a unified front, but the negotiations that produced it were not without friction. The most revealing dispute concerned institutional architecture. France, under its G7 presidency, tabled a proposal for a permanent Critical Minerals Secretariat that would steward the Action Plan launched at the 2025 Kananaskis summit across successive presidencies. The rationale was straightforward: G7 rotating presidencies change annually, and the consistent execution of a long-term minerals strategy requires an institutional home that does not. Five sources familiar with the negotiations, speaking on condition of anonymity to Reuters, confirmed that this was the explicit logic behind the proposal, and that the secretariat would most likely be hosted at either the IEA or the OECD in Paris.
The Trump administration rejected the proposal, pushing instead for bilateral deals and resisting what it characterised as unnecessary multilateral bureaucracy. The US proposal for a formal critical minerals trading bloc also met resistance from allies. The final agreement is a coordination framework, not a binding arrangement, and the secretariat question remains unresolved. As my June analysis of FORGE, Washington's successor to the Minerals Security Partnership, noted in a different but adjacent context, the gap between announcement and institutional reality is one of the defining tensions in Western critical minerals diplomacy. The Évian framework has the same structural vulnerability: it relies on political will that has to be renewed every time the presidency rotates.
The investment picture adds a further layer of complexity. The G7 declaration welcomed the progress represented by 195 projects announced since the beginning of 2026, with 64 billion euros of investment including equity participation and offtake agreements. That is a substantial number on its face. But the IEA's analysis notes that capital costs for new projects in emerging regions are typically 50 percent higher than in incumbent producer countries, and that market forces alone will not deliver diversified supply chains. The growth rate for investment in critical mineral development slowed to just 5 percent in 2024, down from 14 percent the previous year, in part because lithium prices fell more than 80 percent from their 2021-22 peaks, weakening incentives across the sector.
The supply gap for the minerals that matter most is sobering. Non-Chinese production of dysprosium and terbium, the two heavy rare earth elements most critical for defense and electric-vehicle magnets, is projected by McKinsey, CRU Group, and Benchmark Mineral Intelligence to meet less than one-fifth of global demand by 2035. For graphite and rare earth elements, the IEA's own analysis suggests that in a scenario where the leading supplier is removed, alternative supply would cover only 35 to 40 percent of demand by 2035, entirely insufficient to meet mineral needs. Lynas Rare Earths, which became the first company outside China to produce commercial quantities of dysprosium oxide at its Malaysia facility in May 2025, represents real progress. Its quarterly output of dysprosium and terbium combined remains a fraction of what the automotive and defense sectors require. Neha Mukherjee, research manager at Benchmark Mineral Intelligence, put the challenge plainly: "The pace of supply chain diversification will depend on whether policy support translates into investment across the midstream and downstream parts of the supply chain." That translation has not yet reliably occurred.
What the IEA Model Can and Cannot Do
The oil security model that the G7 is attempting to replicate for critical minerals is instructive precisely because it reveals both the possibilities and the limits of the approach. The IEA's oil emergency system works because the commodity in question, crude oil, is relatively fungible: a barrel from one source can substitute for a barrel from another, logistics permitting. Critical minerals are different. The processing technologies, purity specifications, and downstream industrial applications for dysprosium are not the same as those for lithium carbonate or battery-grade graphite. A stockpile that functions as a genuine strategic buffer requires not just physical inventories but the processing capacity and qualified facilities to convert those inventories into usable industrial inputs. As my June reporting on Project Vault's structural paradox illustrated, reserves built without the accompanying processing infrastructure risk becoming sophisticated warehouses rather than genuine resilience mechanisms.
The IEA's published framework for stockpiling design explicitly addresses this complexity. The January 2026 assessment tool evaluates supply risk, alternative supply availability, strategic importance, and feasibility of stockpiling across multiple dimensions for each material. The Brussels workshop in May, which brought together governments and private sector participants including Glencore and Umicore, was designed in part to surface the industry-side constraints that government planners can overlook: the cost of maintaining physical stocks, the degradation characteristics of certain materials over time, the question of where in the value chain to hold inventories, and how release mechanisms can avoid distorting the very markets they are designed to stabilise.
The IEA's own analysis offers a note of measured reassurance on the deterrence function of stockpiles. Even when they are not used, it notes, stockpiles "send a signal to markets that sudden supply shocks or export restrictions need not immediately cripple the system." This is the logic that gave the 90-day oil stock obligation its strategic value: the knowledge that a coordinated release was possible changed the calculus for producers considering a supply squeeze. Whether the same deterrence effect can be achieved for minerals, where the dominant refiner is also a competitor with its own industrial policy objectives, is a question the Évian framework has opened without yet answering.
The 60 percent concentration target for rare earth imports by 2030, with an ambition to reach 50 percent as quickly as possible, is the declaration's most concrete benchmark. It is also, as experts noted throughout the corridors at Évian, an extremely ambitious one. Japan has been attempting to reduce its Chinese rare earth dependence since 2010 and still relies on China for around 80 percent of its rare earth imports, according to Benchmark Mineral Intelligence. The European Union sources all of its heavy rare earth elements from China, 85 percent of its light rare earths, and 98 percent of its rare earth permanent magnets. The United States, per the 2026 US Geological Survey Mineral Commodity Summary, has 100 percent net import reliance for heavy rare earth compounds and metals, with no sustained commercial-scale domestic heavy rare earth processing. The 2030 target, four years away as leaders signed the declaration at Évian, implies a pace of supply-chain restructuring that has never been achieved at this scale.
Conclusion: The Lake and the Long Work Ahead
By the time the final press conferences concluded on the afternoon of June 17, and the motorcades began moving toward Geneva airport, the G7 had produced something real and something incomplete. The real part was institutional: the IEA has a mandate, a coordination platform is being built, and the two pilot minerals, lithium and nickel, give the framework a concrete starting point rather than an open-ended aspiration. The incomplete part was equally visible: a secretariat debate left unresolved, investment figures that sound impressive until measured against the supply gap they need to close, and a 2030 concentration target that assumes a pace of diversification the world has not yet demonstrated it can achieve.
China's Foreign Ministry, meanwhile, was making its own kind of argument, framing the G7 as a small group writing self-made rules, and characterising its own export controls as no different from the regulatory tools that Western economies use routinely. That framing will not persuade Brussels or Washington. But it is designed to persuade the capitals in between: the governments of countries that hold the mineral deposits that both sides need. The legitimacy contest over the rules-based order is not a rhetorical sideshow. It is the environment in which every offtake agreement, every financing deal, and every diversification project has to be negotiated.
Fatih Birol, who has spent years pushing the IEA toward exactly this expanded mandate, invoked the founding spirit of 1974 in his March essay in Time: "With the spirit and focus that governments showed to create the IEA after the 1973 oil shock, we can shift the balance to a more secure economic and energy future." It is a characteristically optimistic formulation. The oil emergency system took decades to mature into the credible deterrent it became, and it was built at a time when the geopolitical landscape was simpler in at least one respect: the supplier concentration problem and the political adversary were not the same actor embedded across every stage of the value chain. The G7 has handed the IEA a genuinely important new assignment in Évian. The lake outside the conference hall was still that clear, cold Alpine blue when the declaration was signed. The harder weather lies ahead.
