China Tightens Grip on Rare Earths Ahead of Expected Trump-Xi Meeting

SINGAPORE—China tightened its control over critical minerals used to make high-tech products including electric vehicles and jet fighters, threatening to reignite trade tensions with the U.S. ahead of an expected meeting between President Trump and Chinese leader Xi Jinping.

China’s Commerce Ministry said Thursday that foreign suppliers must obtain approval from Beijing to export some products with certain rare-earth materials originating from China if they account for 0.1% or more of the good’s total value. Goods produced with certain technologies from China are also subject to the export controls. Both restrictions apply to products manufactured outside of China.
