China’s October rare earth export controls were a reaction to a late-September US escalation that extended entity list restrictions to any affiliate 50% owned by a listed party, boosting coverage from roughly 1,400 Chinese firms to an estimated 20,000 according to policy analysts.
The Bureau of Industry and Security’s new rule automatically subjects majority-owned subsidiaries of entity list and military end-user designees to the same license requirements, closing a known loophole that allowed diversion through unlisted affiliates. Law firm summaries and the federal register confirm the effective-date details, the 50% ownership trigger, and new diligence duties for exporters.
This 👇 is the huge US escalation that decided China to roll out its rare earths export controls: in the end of September the Trump administration increased he number of Chinese companies on the "Entity List" by 14 times (!), from 1,400 to 20,000.

Meaning 14 times more Chinese… https://t.co/vr11eTaAbN
While the US government does not publish an official tally of covered affiliates, the rule itself states the consolidated screening list will no longer exhaustively reflect affected entities because affiliates are captured by ownership rather than by name.
Beijing allegedly moved to tighten rare earth export controls in response, adding more elements and dozens of processing-equipment items to license requirements, denying defense-related uses, and routing semiconductor applications to case-by-case review. China’s Commerce Ministry framed the step as a national-security measure over dual-use technologies central to magnets, electronics, and aerospace.
Trade flows show stress building even before the rule took hold in full. China’s exports of rare earth magnets fell 6.1% month over month in September to 5,774 tons from 6,146 tons in August, reversing a three-month climb.
Europe’s parallel moves intensified the feedback loop. The Dutch government seized control of Nexperia to prevent IP flight, a step that triggered Chinese countermeasures around the firm’s products and underscored how US rules radiate through allied policy choices.
