China expanded controls to five more rare earths and processing technologies, restricting defence and advanced semiconductor users and foreign producers.
Beijing expanded export controls on Thursday, adding five rare earth elements and a slate of refining technologies while tightening rules for defence and advanced semiconductor users.
Holmium, erbium, thulium, europium and ytterbium were added to the restricted list, and dozens of pieces of mining and processing equipment were newly controlled. The ministry said foreign producers that use Chinese materials or equipment will need Chinese export licences for downstream products, even when no Chinese firm is involved in the transaction.
Overseas defence end‑users will be denied licences outright; advanced semiconductor applications will face case‑by‑case scrutiny. The measures target chips at 14nm or below (and more advanced nodes), memory stacks of 256 layers or more, associated production equipment, and AI research with potential military uses.
The new element and equipment curbs take effect on November 8, while the compliance rules for foreign producers begin on December 1. China supplies over 90% of processed rare earths and magnets, so the move has immediate supply‑chain implications. Enforcement details remain unclear, and some domestic rare earth stocks jumped sharply after the announcement.
Observers note the timing ahead of a planned U.S.–China summit, framing the measures as both industrial policy and geopolitical leverage.
