International Energy Agency Calls for Urgent Supply Chain Diversification as Dependence on Chinese Critical Minerals Raises Economic and Security Concerns
The International Energy Agency (IEA) has issued one of its strongest warnings yet about the global dependence on China’s rare earth supply chain, estimating that up to $6.5 trillion worth of downstream industrial production outside China could be at risk each year if Beijing fully implements its expanded export restrictions on rare earth elements.
The warning highlights the growing strategic importance of critical minerals, which have become essential to modern industries ranging from electric vehicles and renewable energy to defense systems, consumer electronics, aerospace, and artificial intelligence. Although rare earth elements account for only a small fraction of manufacturing costs, they are indispensable components in thousands of advanced products. A disruption in supply could therefore have far-reaching consequences for global manufacturing and economic growth.
Rare Earths Have Become a Strategic Asset
Rare earth elements consist of 17 metallic elements used in high-performance magnets, batteries, semiconductors, military equipment, wind turbines, electric motors, smartphones, and advanced electronics. China dominates not only mining but also the refining and processing of these materials, giving it significant influence over global supply chains.
The IEA noted that China’s expanded export controls and licensing requirements have transformed what was once considered a theoretical supply-chain risk into a tangible geopolitical concern. Governments and manufacturers are increasingly recognizing that heavy reliance on a single supplier leaves critical industries vulnerable to political disputes, trade restrictions, and supply disruptions.
Trillions of Dollars in Manufacturing Could Be Affected
According to the IEA, if China’s export restrictions were fully enforced, approximately $6.5 trillion in downstream production outside China could face disruptions.
Industries most exposed include:
- Automotive manufacturing
- Electric vehicles
- Aerospace and aviation
- Defense and military equipment
- Consumer electronics
- Renewable energy technologies
- Industrial machinery
- Artificial intelligence infrastructure
The agency estimates that the United States and Europe would bear nearly half of the potential economic impact because of their heavy dependence on imported processed rare earth materials.
Graphite Restrictions Add Another Layer of Risk
The IEA also warned about China’s planned export controls on graphite, another critical material used extensively in lithium-ion batteries for electric vehicles and energy storage systems.
If fully implemented, graphite restrictions could place an additional $300 billion in downstream industrial production at risk. China currently accounts for more than 90% of the world’s processed graphite supply, making diversification particularly challenging for battery manufacturers and clean-energy companies.
Governments Accelerate Supply Chain Diversification
In response to growing geopolitical risks, governments across North America, Europe, and Asia have significantly increased investment in alternative critical mineral supply chains.
The IEA reported that public financing commitments for new mining, refining, and processing projects have increased more than fourfold, reaching approximately $65 billion by 2025.
Several new rare earth refining facilities, particularly in the United States and Malaysia, have already begun reducing China’s dominance in global processing. According to the agency, China’s share of global rare earth refining declined from around 90% in 2023 to 85% in 2025 and could fall to approximately 70% by 2035 if planned projects are completed on schedule.
Building Resilience Through Strategic Stockpiles
Beyond expanding production, the IEA recommends that countries cooperate internationally to establish strategic reserves of critical minerals.
The agency proposes creating stockpiles of 11 high-risk minerals, estimating an initial investment of approximately $9.2 billion, followed by annual maintenance costs of around $900 million.
While these figures appear substantial, the IEA argues they are minimal compared with the trillions of dollars in economic activity that could be disrupted by prolonged shortages. Strategic reserves would help manufacturers maintain production during temporary supply interruptions and reduce vulnerability to geopolitical shocks.
Mineral Security Becoming a National Priority
IEA Executive Director Fatih Birol emphasized that the value created by modern industries depends on relatively small quantities of minerals whose supply chains remain highly concentrated.
The report argues that paying a premium to diversify sources of supply should be viewed as a form of economic insurance rather than an unnecessary expense. As geopolitical competition intensifies, governments are increasingly treating access to critical minerals as a matter of national security alongside energy security and technological leadership.
Looking Ahead
The IEA’s latest report underscores how critical minerals have become central to the global economy. China’s dominant position in rare earth processing gives it considerable influence over industries that power the modern world, from electric vehicles and renewable energy to defense systems and advanced electronics.
While governments and businesses are investing heavily in alternative supply chains, developing new mines and processing facilities will require years of investment and international cooperation. Until those efforts significantly reduce supply concentration, global manufacturers will remain exposed to disruptions stemming from export restrictions and geopolitical tensions. The report serves as a reminder that securing reliable access to critical minerals is no longer simply an industrial challenge—it has become a strategic economic priority for countries seeking resilient supply chains in an increasingly uncertain world.
