Some Chinese rare earth producers have stopped shipping the materials to the United States despite holding valid export licenses, fearing repercussions from Chinese authorities, sources familiar with the development told Reuters. The halt is not a formal government export ban — the firms involved hold valid licenses — but a voluntary freeze driven by caution, which underscores how export control enforcement risk is now shaping commercial behavior even where formal rules permit trade.

The renewed standoff in rare earths comes weeks before Chinese President Xi Jinping is expected to visit Washington for a summit with U.S. President Donald Trump at the end of this month. Rare earths — a group of 17 metals used in products ranging from electric vehicle motors and wind turbines to smartphones and precision-guided weapons — have repeatedly served as a leverage point in U.S.-China trade disputes, making supply signals ahead of the summit politically significant.

According to Reuters' sources, a few Chinese suppliers have been refusing to export rare earths to the U.S. since the beginning of August. That timing coincides with China's announcement that it was placing the Responsible Business Alliance (RBA) — the organization behind the Responsible Minerals Initiative (RMI) and its RMAP assessments — together with the labor rights organization Verité on its countermeasure list.

One of Reuters' sources said the Chinese rare earth firms are wary of being punished by China for complying with the RMI guidance and due diligence procedures. Other Chinese firms have been avoiding rare earth exports to the U.S. even though they hold licenses, preferring not to become entangled in the geopolitics and unpredictable trade behavior of the two rivals.

In a July report, the International Energy Agency (IEA) said that despite improvements in some areas — such as targeted policies and investment support for rare earth supply chains outside China — the global critical minerals market remains heavily concentrated among leading suppliers, with China leading the mining and refining of many of the metals. The market remains highly concentrated, and new threats to supply security have emerged in recent months as China has curbed exports of some rare earth elements, the agency said (Global Critical Minerals Outlook 2026). This concentration means that even self-initiated shipment freezes by a handful of Chinese producers can tighten availability for downstream manufacturers in the U.S. and allied economies, where alternative refining capacity remains limited.

The Chinese government introduced major export controls on heavy rare earth elements last year. Although further expanded controls have been suspended until November 2026, the IEA said in its annual Global Critical Minerals Outlook 2026 report in July that their full implementation — if China decides to proceed — could put an estimated $6.5 trillion per year of downstream production outside China at risk across the automotive, high-tech, defense, and energy sectors. The November deadline for the suspended expanded controls, falling shortly after the planned Xi-Trump summit, is likely to be a key checkpoint for whether rare earth supply tensions ease or deepen.
