Highlights

• The U.S. and Japan launched a Critical Minerals Action Plan using trade policy, border mechanisms, and potential price floors to counter China's dominance in rare earth processing and reduce supply chain vulnerabilities.
• While the strategic alignment is sound and draws on Japan's 2010 rare earth crisis experience, the plan lacks operational details on scaling separation capacity, metallization, and magnet manufacturing at commercial levels.
• This policy signals meaningful coordination on industrial tools and supply chain diversification, but until commercial-scale processing infrastructure and pricing systems are established, China retains full integration from mine to magnet.

A quiet press release—easy to miss, harder to dismiss.  As the United States and Japan agree to coordinate on critical minerals through trade policy, border mechanisms, and the potential introduction of price floors, aimed at reducing supply chain vulnerability and protecting downstream industries. Two major economies are teaming up to secure materials like rare earths—but they still rely heavily on China to process them.

Ambassador Jamieson Greer (opens in a new tab) announced the enactment of the U.S.-Japan Action Plan on Critical Minerals. Under this Action Plan, the United States and Japan will develop strategic trade policies and border mechanisms to mitigate supply chain vulnerabilities and protect the downstream industries that depend on critical minerals imports. In the picture below, Greer meets with Sanae Takaichi (opens in a new tab), Prime Minister of Japan.

Steel Meets Reality: What Holds True

The strategic logic is sound—and grounded in history.

Japan has lived this before. The 2010 rare earth shock, when China restricted exports, forced Tokyo to rethink supply chains. That institutional memory matters. Alignment with the U.S. is not symbolic—it is pragmatic. The reference to price floors is especially important. This signals a shift away from pure market reliance toward managed pricing mechanisms to counter China’s state-backed overproduction and price suppression.

Equally important is the focus on downstream industries—magnets, motors, and advanced manufacturing. This is where economic value concentrates and where supply disruptions are most damaging.

The Missing Middle: Where the Plan Thins

But the plan remains high-level—strategic, not operational.

There is no defined pathway to:

• Scale rare earth separation capacity (the core bottleneck)
• Build metallization and magnet manufacturing at commercial levels
• Sustain projects through price volatility and capital risk cycles

Without midstream execution, policy coordination remains scaffolding without structure.

The Language of Strategy—or Diplomacy?

The tone is confident. The substance is early-stage.

Phrases like “expand production” and “diversify supply” describe intent—not implementation. There are no timelines, no funding commitments, no project-level details. But of course, that does not mean that these things won’t occur. It is deliberate strategic ambiguity—policy signaling without operational specificity.

Why This Matters for Investors

This is the signal beneath the signal.

The U.S. and Japan are converging on core industrial policy tools:

• Coordinated trade and enforcement mechanisms
• Early-stage price stabilization concepts
• Allied supply chain alignment

This is meaningful—and increasingly aligned with Rare Earth Exchanges™ principles.

But the gap remains: Until we see commercial-scale heavy rare earth separation, magnet manufacturing capacity, and bankable offtake plus pricing systems, China retains the only fully integrated system—from mine to magnet.

In rare earths, alliances matter—but infrastructure, processing, and pricing power decide outcomes. And the only way we will get there in America and other places in the West is via serious collaboration, shared vision and goals, industrial policy, and commitment to long-term investment across the value chain.
