China Rare Earth Firms Refuse US Shipments

Some Chinese rare earth suppliers have refused to ship materials to U.S. customers since early August, citing fears of retaliation from Beijing and concerns that shipments could ultimately reach sanctioned users. The disruption, reported by Reuters on September 4, 2026, adds pressure to already tight critical mineral supply chains just weeks before Chinese President Xi Jinping is scheduled to visit Washington on September 24. According to sources familiar with the trade, the shipment refusals began after China imposed sanctions on the Responsible Business Alliance, a U.S. supply chain monitor, in early August. Chinese companies became wary of punishment from Beijing for complying with the due diligence framework of the Responsible Minerals Initiative, a global audit program connected to the RBA. Other suppliers had already halted U.S. shipments in recent months to avoid geopolitical entanglement, with one source citing four instances where Chinese firms declined to send material over fears it could be resold to prohibited users. The total number of affected suppliers and shipments remains unclear. The issue has become part of U.S. planning for Xi's upcoming visit. U.S.
