Highlights

• Japan, France, and Canada are exploring alternatives to a U.S.-led critical minerals trade bloc, revealing fractures in Western strategy despite agreement on China's supply chain dominance.
• The true bottleneck isn't trade policy but industrial capacity: China controls 85-90% of rare earth separation and 90% of magnet manufacturing, infrastructure that takes decades and billions to replicate.
• Under the Great Powers Era 2.0 thesis, rare earth supply chains now operate as geopolitical systems shaped by security policy rather than markets, making Western diversification both strategically urgent and structurally difficult.

Is it the case that Japan, France, and Canada are exploring alternatives to a U.S.-led critical minerals trade bloc? If so, as is claimed in a March 7 Reuters piece, does this reveal new tensions within Western efforts to secure rare earth supply chains outside China? Officials speaking at a Toronto mining conference suggested options such as import quotas, mining subsidies, and a “buyers’ club” alliance to support non-Chinese supply. The discussion comes just weeks after U.S. Vice President JD Vance proposed a U.S.-anchored preferential trade bloc for critical minerals. For investors watching the rare earth sector, the message is clear: the West agrees on the strategic threat posed by China’s dominance—but Washington and its allies are not yet aligned on how to solve it.

The Industrial Reality Behind the Headlines

Several points in the Reuters repor (opens in a new tab)t reflect well-established facts about the rare earth supply chain. Canada correspondent Divya Rajagopal notes China dominates the midstream and downstream segments of the industry. It controls roughly 85–90% of global rare-earth separation capacity and about 90% of permanent magnet production, a stage where rare earths become essential components in electric vehicles, wind turbines, robotics, and advanced weapons systems.

Japan learned this vulnerability firsthand during the 2010 rare-earth export restrictions following the Senkaku dispute, prompting Tokyo to invest in supply diversification—most notably through Australia’s Lynas rare-earth project, now the largest non-Chinese producer of separated rare-earth oxides. And Canada’s proposed “buyers’ club” model, where governments or industries guarantee long-term purchases, is also considered a rational approach. Stable offtake contracts can help de-risk projects that otherwise struggle to compete with Chinese supply.

Overreach on Reality?

Several elements of the report and the unfolding situation seemingly drift into oversimplification. The claim that China controls “over 90% of rare earth metals” is technically inaccurate. China’s dominance lies primarily in processing, separation chemistry, and magnet manufacturing—not global reserves or mine production alone.

More importantly, the article implies that trade blocs, quotas, or purchasing alliances could materially shift the market. They cannot—at least not quickly.

As Rare Earth Exchanges™ has continuously reported since our launch in late 2024, the true chokepoint in the rare earth system is industrial separation and magnet manufacturing capacity, not trade agreements. Building those capabilities requires billions of dollars, advanced chemical engineering, and years of operational learning.

In short, policy moves faster than metallurgy.

The Growing Tension with Washington’s Strategy

The emerging policy divergence also reflects growing unease with Washington’s approach. The United States has pursued its own industrial strategy—ranging from Defense Production Act funding and Department of Defense magnet initiatives to potential strategic stockpiling mechanisms sometimes referred to as “Project Vault.” Yet allies appear reluctant to fully align behind a U.S.-centered mineral trade bloc, instead experimenting with their own frameworks.

Japan favors project finance and industrial partnerships.

Canada is pushing production alliances and buyers’ clubs.

Europe increasingly supports supply diversification mandates and quotas.

What emerges is not a unified Western strategy—but parallel experiments in critical mineral security.

REEx GPE 2.0 Thesis

Apply the Rare Earth Exchanges Great Powers Era 2.0 thesis, and the situation becomes even more complicated. The thesis argues that rare earths and critical minerals have moved beyond being simple commodities and are now strategic instruments of geopolitical power. Because these materials underpin technologies ranging from electric vehicles and wind turbines to missiles, drones, and advanced electronics, governments increasingly treat their supply chains as matters of national security rather than purely economic markets. This shift makes the race to build non-Chinese supply chains far more complex. Western allies are pursuing competing strategies—from U.S. industrial policy and stockpiles to Japan’s project financing and Canada’s buyers’ alliances—while China still dominates the industrial core of rare earth separation and magnet manufacturing.

At the same time, resource nationalism, financial speculation, and rising military demand are introducing new instability into already fragile supply chains. The challenge is compounded by a massive infrastructure gap: China spent decades building its integrated rare earth ecosystem, while the West is attempting to replicate it in years.

This mounting tension, conflict, and ongoing transformation from a previous world order likely lead to a higher probability of militarism, at least manifesting in instances that effectively disrupt supply chain choke points, build leverage, and gain advantage.

In short, under Great Powers Era 2.0, rare earth supply chains operate less like markets and more like geopolitical systems shaped by security policy, diplomacy, and industrial strategy, making the push for “ex-China” supply both strategically urgent and structurally difficult. 

The Signal Investors Should Notice

For investors, the most important takeaway is not diplomatic theater but strategic fragmentation. The West clearly recognizes that rare earth and select critical mineral supply chains are strategic infrastructure, essential to defense systems, electrification, and advanced manufacturing.

Yet despite America’s first-mover prominence, no single model has emerged to replace China’s integrated ecosystem. And until large-scale separation, refining, and magnet manufacturing capacity is built outside China, Western supply chains will remain structurally vulnerable.

The Bottom Line

While recent news captures real geopolitical movement, as is often the case media are understating the scale of the challenge. Diversifying rare earth supply is not simply a matter of alliances or quotas. It requires industrial chemistry, capital, and patience measured in decades, not a few years.  Until that infrastructure is in place, China will remain the gravitational center of the rare-earth universe.

And the West—including the United States—will continue searching for the blueprint.
