Why the May 2026 Trump–Xi Summit Failed to Resolve the Rare Earths Dispute

Both sides discussed the possibility of extending or clarifying an existing trade truce that had eased some export restrictions earlier. But the talks stopped short of a definitive deal on restoring predictable flows of rare earth materials to U.S. companies.

Why no rare earth agreement emerged

Several factors made a deal difficult despite the issue being central to the summit.

Rare earths are a major strategic bargaining chip. China’s dominance in the supply chain gives Beijing significant leverage in broader negotiations over tariffs, semiconductors, and security issues. Giving up that leverage without concessions elsewhere would reduce China’s negotiating power.

The issue is tied to wider trade disputes. Rare earth exports are intertwined with the larger U.S.–China economic confrontation, including tariffs and technology restrictions. Because the disputes are linked, resolving one piece without progress on others has proven difficult.

Enforcement questions remain unresolved. Even where agreements exist in principle, Washington has pushed for clearer guarantees that licensing and customs rules will not restrict actual shipments. Reports before the summit indicated that exports were still being throttled despite the earlier truce framework.

How export restrictions affect U.S. companies

Chinese export controls are creating uncertainty across several industries that depend heavily on rare earth materials.

Manufacturers in sectors such as defense, automotive production, electronics, and clean‑energy equipment rely on rare earth magnets and refined minerals sourced largely from China. When shipments slow or licensing becomes unpredictable, supply chains can stall.

The issue has also become a test of whether diplomatic agreements translate into real-world supply flows. Some companies reported shortages that appeared inconsistent with the expectations set by earlier trade arrangements.

More broadly, the situation reinforces a long‑standing concern in Washington: that dependence on Chinese processing capacity leaves critical industries vulnerable to geopolitical pressure.

Washington’s strategy to build alternative supply chains

In response, the United States has begun a broad effort to reduce reliance on Chinese rare earth supplies.

One challenge is structural. Even where the United States has mining capacity, it lacks sufficient processing and refining infrastructure. As of 2024, the country remained 100% import‑reliant for 12 critical minerals and more than 50% reliant for dozens more.

To address this gap, policymakers have begun pushing several initiatives:

Domestic production and processing. The Pentagon and federal agencies are backing efforts to expand U.S. rare earth mining, separation, and magnet manufacturing capacity.

Public‑private partnerships. A major example is the collaboration between the Department of Defense and MP Materials to build a more complete domestic rare‑earth magnet supply chain centered on the Mountain Pass mine and U.S. magnet production facilities.

Supply‑chain finance and investment. U.S. defense officials are also working with private investors and financial institutions to fund new refining and magnet‑manufacturing capacity designed to compete with Chinese dominance.

Allied coordination. The United States is coordinating with partners and G7 countries to diversify global supplies of critical minerals and develop new mining and processing projects outside China.

These efforts aim to build a resilient supply network over the next decade, though industry analysts say China’s current dominance will take years to replicate elsewhere.

What the summit outcome means for U.S.–China relations

The Beijing meeting lowered the immediate diplomatic temperature but did little to resolve the deeper structural conflict between the two countries.

Rare earths remain a central flashpoint because they sit at the intersection of trade policy, industrial strategy, and national security. As long as China maintains tight control over the supply chain, the issue will continue to influence negotiations on tariffs, technology controls, and strategic competition.

The biggest risk lies ahead. The current U.S.–China trade truce runs through late 2026, and if negotiations fail to produce clearer rules before then, rare earth restrictions could again become a trigger for renewed tariffs, export controls, or retaliation.

For now, the summit showed that both sides prefer to keep negotiating—but the strategic contest over critical minerals is far from resolved.
