• U.S. officials say China has fulfilled only two-thirds of its rare earth supply commitments under the trade truce.
  • The shortfall persists despite the September summit and an extension of the broader trade arrangement to January 2027.
  • Licensing delays for sensitive sectors like aerospace and semiconductors continue to disrupt supply chains.

Compliance Gap

China has not restored rare-earth supplies to the levels Washington understood Beijing had promised under their trade truce, according to U.S. officials. The assessment that China is meeting only about two-thirds of its commitments circulated ahead of the September 2026 Trump–Xi summit in Washington, and it remains a point of contention as negotiations continue. The two sides have preserved the truce without resolving the underlying dispute over export licensing and supply volumes.

Licensing Bottleneck

The core issue is not a shortage of ore but a processing bottleneck. China dominates the downstream rare-earth supply chain, accounting for approximately 70% of mining and 90% of separation and refining for magnet rare earths, according to data from the U.S. Geological Survey and International Energy Agency. Even as the U.S. pushes for alternative sources, opening a mine elsewhere does not quickly create an independent supply of usable metals or finished magnets.

China’s Ministry of Commerce confirmed that the broader bilateral trade arrangement was extended to January 10, 2027, buying negotiating time. However, the pre-existing rare-earth licensing system remains in place. While automotive and consumer-electronics licenses have been flowing, sensitive aerospace and semiconductor applications continue to face delays, according to people familiar with the matter. The stop-start deliveries have frustrated manufacturers who depend on reliable access to materials like yttrium and scandium.

Uneven Impact

The consequences vary across industries. Aerospace manufacturers rely on yttrium for heat-protective coatings in aircraft engines, and unreliable supply can constrain production even when the material represents a small fraction of total costs. Semiconductor producers have faced scandium shortages, while restrictions on related critical minerals like indium—used in electronics—create additional supply-chain risks. Indium is not a rare earth, but it is swept up in the broader export-control dispute.

Defense and other sensitive users face heightened licensing difficulties due to potential military applications, making alternative sourcing particularly urgent. For the global economy, the immediate risk is concentrated industrial disruption rather than a quantifiable inflation shock. Delays can propagate from a relatively small input into higher-value manufacturing chains, but the sources reviewed do not establish a measurable consumer-price increase attributable to the shortfall.

Diplomatic Maneuvering

The September 24 summit did not settle rare-earth access. The subsequent U.S. statement said the countries would keep working toward returning shipments to “appropriate levels,” without announcing specific quantities or the elimination of export licensing. That ambiguity helps explain why both sides can describe the agreement differently. Washington portrayed general licenses as effectively removing restrictions, while Beijing retained discretion over approvals, quantities, and timing.

China introduced licensing requirements on seven medium and heavy rare-earth categories in April 2025, citing national security and nonproliferation obligations. Additional measures in October 2025 sought to extend controls to some overseas products containing Chinese-origin rare earths. The truce suspended those newer measures, but the earlier licensing architecture remained intact. “The key is for both governments to credibly signal stability,” said Cory Combs of Trivium China, according to a Reuters (NASDAQ:TRI) report.

Parallel Squeezes

The problem is not confined to U.S. customers. Chinese yttrium exports to Japan fell 98% year over year during January–August 2026, while terbium exports dropped to zero, according to customs figures cited in an analysis by University of Tokyo professor Naoko Munakata. These are material- and destination-specific figures, not a measure of all Japanese rare-earth imports. Europe is also negotiating licensing access separately, with China’s Ministry of Commerce saying in October it would continue facilitating rare-earth export licenses to the EU while seeking reciprocal treatment for Chinese priority cases.

Meanwhile, Chinese indium shipments fell about two-thirds globally and 77% to the United States over the 14 months after February 2025, compared with the preceding period, Reuters reported in May. That is a separate statistic from the headline’s “two-thirds of commitments” claim, but it shows the dispute extends beyond rare earths into semiconductor-related materials.

What to Watch

The near-term outlook points to continued negotiations and uneven deliveries rather than a confirmed restoration of unrestricted supply. The extension to January 10, 2027 reduces immediate escalation pressure, but licensing decisions and actual shipments remain the operational test. Munakata’s analysis argues that durable resilience requires more than alternative mines: countries need separation and refining capacity, manufacturing expertise, dependable customer demand, and arrangements to allocate scarce inventories during disruptions. She also warns that low-priced Chinese supply can undermine the economics of competing projects.

The most informative indicators will be material-specific shipment volumes, license approval speed and scope, and actual non-Chinese processing output—not simply the announcement of another diplomatic truce. For now, the evidence suggests that an agreement to stabilize relations can coexist with persistent supply constraints.
