China has broadened its rare earth export controls, adding five new elements and tightening oversight of semiconductor and defense users, in a move that could reshape global supply chains just weeks before the Trump–Xi summit in South Korea.
The new restrictions, effective November 8, extend to holmium, erbium, thulium, europium, and ytterbium, and to dozens of processing technologies. From December 1, foreign companies using Chinese rare earths or refining equipment will also need a Chinese export licence — a measure mirroring U.S. chip export rules.
The Commerce Ministry said licenses will be denied for military-linked users and reviewed individually for firms developing advanced chips or AI with defense potential. The affected chip types include 14nm processors and 256-layer memory.
China, which refines over 90% of global rare earths, said the scope was “limited,” but analysts see the move as a strategic escalation. “We’re entering structural bifurcation — China localizing its value chain while the West races to build alternatives,” said Neha Mukherjee of Benchmark Mineral Intelligence.
Shares in rare earth producers such as China Northern Rare Earth Group and U.S.-based Energy Fuels surged following the announcement, reflecting expectations of tighter supply.
