China announced Tuesday it is banning exports to the United States of gallium, germanium, antimony and other key high-tech materials with potential military applications, as a general principle, lashing back at U.S. limits on semiconductor-related exports. 

The Chinese Commerce Ministry announced the move after the Washington expanded its list of Chinese companies subject to export controls on computer chip-making equipment, software and high-bandwidth memory chips. Such chips are needed for advanced applications.

      Edit: I wouldn’t be surprised if the places in the US producing high-quality gallium are using poor-quality Chinese gallium as feedstock though.

        They are, but we have plenty of Zinc mining we can get it from ourselves. It’s just an economics matter, so we’d subsidize that. We only use enough to fill one truck load per year. So it’s likely we’d just get a defense contractor to do it and subsidize it
