(Reuters) -China has banned exports to the U.S. of items related to the minerals gallium, germanium and antimony that have potential military applications, its commerce ministry said on Tuesday, a day after Washington's latest crackdown on China's chip sector. Beijing's directive on so-called dual-use items with both military and civilian use, which cites national security concerns and takes immediate effect, also requires stricter review of end-usage for graphite items shipped to the U.S. "In principle, the export of gallium, germanium, antimony, and superhard materials to the United States shall not be permitted," the ministry said.
