China Vows Countermeasures as U.S. Sets 100% Tariff and Software Controls in Rare-Earth Clash

Beijing calls its rare‑earth export rules lawful, casting the dispute as a test of critical supply chains.

Overview

  • President Trump announced an additional 100% tariff on Chinese imports effective November 1 or earlier and new U.S. export controls on “critical” software.
  • China’s Ministry of Commerce defended the rare‑earth measures as legitimate, urged Washington to reverse course, and warned of firm retaliatory steps if the tariff threat proceeds.
  • Beijing’s tightened licensing expands controls on rare‑earth minerals, related processing technologies and certain end uses, a significant move given China’s outsized share of global processing and magnet production.
  • Financial markets sold off on the escalation, with Wall Street posting its steepest drop since April as the Nasdaq fell 3.56% and the S&P 500 2.71%, while gold jumped sharply.
  • Diplomatic uncertainty deepened as Trump cast doubt on an APEC meeting with Xi, a follow-up call was reportedly postponed, and reciprocal port-fee measures are set to take effect on October 14.
