China Reported to Curb Rare-Earth Exports to Japan as G7 Sets Washington Talks

Conflicting signals over the scope of Beijing’s controls have raised fears of supply disruptions beyond defense contractors.

Overview

  • The Wall Street Journal, cited by Reuters and other outlets, reports China has begun restricting shipments of heavy rare earths and rare-earth magnets to Japanese companies and has effectively paused export-license reviews across industries.
  • Beijing on Jan. 6 announced a ban on exports of dual-use items to Japan, and Commerce Ministry spokesperson He Yadong said the measures target military firms and will not affect normal civilian trade.
  • Japan has raised concerns with G7 partners and the United States, and a U.S. Treasury spokesperson confirmed finance ministers will meet in Washington on Monday to discuss shoring up rare-earth supplies.
  • Nomura estimates the restrictions could cost Japan about $17 billion over a year if sustained, reflecting the broad industrial exposure to rare-earth inputs.
  • Japanese media report delays for sake and food shipments at Chinese customs, and analysts note Japan still relies on China for roughly 60–70% of its rare-earth supplies despite diversification efforts.
