China Halts Exports of Rare Semiconductor Minerals, Escalating Tech War with U.S.
-
China stopped exporting two rare minerals, gallium and germanium, in August that are essential for making semiconductors. China produces about 80% of the world's gallium and 60% of germanium.
-
The export halt came after China imposed curbs in July citing national security reasons. The moves escalate an ongoing tech war with the U.S. over advanced chipmaking capabilities.
-
The export controls could hurt China's economy and drive supply chains out of the country. Prices for gallium have already fallen within China as inventories pile up.
-
The release of Huawei's new Mate 60 Pro smartphone with an advanced chip despite U.S. sanctions has created political pressure for more chip export curbs on China.
-
Additional U.S. sanctions on Chinese tech companies like Huawei and chipmaker SMIC are expected this quarter to tighten the chip ban on China.
