Chinese Rare Earth Suppliers Are Refusing US Orders Weeks Before Xi Visits Washington
A handful of Chinese rare earth suppliers have stopped shipping to American customers since early August. No export ban was announced and no licence was formally revoked. The suppliers simply declined the business, out of concern that filling those orders would put them on the wrong side of Beijing.
The trigger was China’s decision in early August to sanction the Responsible Business Alliance, the American body behind a widely used supply chain auditing framework. Chinese firms that participate in that framework, and that ship to US buyers who require it, now face a compliance question with no safe answer. Some resolved it by walking away from the customer.
Timing makes this larger than the tonnage involved. Xi Jinping is expected in Washington on September 24, and rare earth access has moved onto the American planning agenda for that visit. US officials have spent the past year asking China to honour the commitments made at Busan and in follow-up talks, which were meant to keep export licences flowing predictably. The commitments were made. The flow is still not predictable.
Aggregate export numbers look reasonable, and that’s part of what makes this hard to argue about in public. Shipments of many rare earths and magnets have recovered substantially since the restrictions of April 2025. Look underneath the aggregate and the picture changes. Yttrium, indium phosphide and tungsten, which matter for aerospace, chipmaking and defence work, are trading near record prices with tight supply. American yttrium imports are running at roughly half their 2024 level even as China ships large volumes elsewhere. Medical device and energy firms report the same licence delays. Buyers in India and Japan have it worse.
That pattern is the actual mechanism, and it’s worth naming clearly. Beijing doesn’t need an embargo. A licence regime that approves most things most of the time, while slowing or quietly refusing a narrow band of militarily useful materials to specific destinations, produces the same effect with none of the political cost. There is no announcement to condemn and no measure to reciprocate against. Every affected company negotiates alone.
Beijing’s framing is that the RBA sanctions were retaliation. Since December, the FCC has moved against Chinese electronics testing labs, drones, consumer routers, submarine cables, advanced robotics and power inverters. From that vantage the auditing framework was an obvious pressure point: American in origin, embedded in the procurement rules of thousands of Western buyers, and reachable through Chinese suppliers rather than through Washington.
Expect a partial thaw before the summit. Several US firms have received licences after long waits, and more approvals in the run-up would let Beijing deflect the charge that it isn’t honouring the truce, at very little cost. Analysts covering the sector expect exactly that.
The thaw would be tactical, and anyone treating it as resolution will be back here within a quarter. The underlying position hasn’t changed since 2025. China holds a processing chokepoint in materials that Western defence, semiconductor and energy supply chains cannot substitute quickly, and it has now demonstrated three separate ways to squeeze it: formal export controls, licence throttling, and sanctions aimed at the compliance infrastructure that Western buyers depend on. Each is more deniable than the last.
Western mine and refinery projects are funded and slow. The gap between the funding and the output is the whole exposure, and no summit closes it.
