• Nato's reliance on China for critical minerals threatens defense supply chains and funding initiatives.
  • Policy momentum is accelerating toward diversification and stockpiling, but costs remain high.
  • Analysts warn that without action, production delays and increased costs could undermine alliance readiness.

Supply Chain Vulnerability

Nato's ambitious funding plans to modernize its defense infrastructure are facing a significant hurdle: the alliance's heavy dependence on China for critical raw materials like rare earths, essential for advanced weapons systems and electronics. According to defense analysts, China controls over 60% of global rare earth mining and an even larger share of processing, giving it leverage that could disrupt Nato's supply chains during a crisis.

“We've seen how China has used export controls as a strategic tool in the past,” said a senior policy advisor familiar with Nato's internal discussions. “If tensions escalate, allied defense production could grind to a halt.” The risk is particularly acute for systems like precision-guided munitions and radar technology, which rely on magnets, batteries, and semiconductors that require these minerals.

Policy Shift Underway

In response, Nato members are accelerating efforts to diversify sourcing and build domestic processing capacity. The U.S. and EU have launched initiatives to fund critical mineral projects in allied countries, including Canada and Australia, and are exploring joint stockpiling arrangements. “This is no longer just an economic issue—it’s a core security concern,” said a European defense official who spoke on condition of anonymity. “We’re treating critical minerals like we treat munitions reserves.”

However, these efforts face substantial hurdles. Building new mines and refineries can take a decade or more, and environmental opposition often delays projects. Meanwhile, the cost of stockpiling is immense, with some estimates suggesting that meeting Nato's needs could require tens of billions of euros in upfront investment.

Implications for Funding

The dependence on China is already affecting Nato's funding plans. Some proposed projects, such as a joint munitions acquisition fund, are being reassessed amid concerns that they could be vulnerable to supply disruptions. “Without a diversified supply base, any funding commitment is essentially a bet that China won't pull the plug,” said a defense economist at a Brussels-based think tank. “That’s a risk that policymakers are increasingly unwilling to take.”

Nato officials have declined to comment on specific funding allocations, but sources indicate that a portion of the alliance's new €1 billion innovation fund may be redirected toward critical mineral projects. “We need to invest in the entire pipeline, from mining to recycling,” said another official. “It’s the only way to secure our long-term readiness.”

Broader Context

The challenge is part of a wider geopolitical competition. China has already demonstrated its willingness to use mineral leverage, as seen in its 2010 rare earth export restrictions targeting Japan. More recently, it imposed controls on gallium and germanium, affecting semiconductor production worldwide. “This is a pattern,” said a professor of strategic studies at a U.S. war college. “Nato needs to treat critical minerals as a first-order security issue, not just a trade concern.”

The alliance is also exploring alternatives, such as recycling and substitution, but these technologies are still in early stages. In the short term, the focus remains on funding new extraction and processing capacity, even as the clock ticks on existing stockpiles.

Correction: An earlier version of this article misstated the share of rare earth processing controlled by China. The correct figure is approximately 90%, not 60%. The error has been corrected.
