How this China ban may be a problem for the US tech industry

China has announced a ban on exports of key minerals to the US, which may hit the manufacturing in the country’s tech sector. The ban comes a day after the US announced export restrictions on 140 Chinese companies and stricter controls on chipmaking equipment.
According to a report by news agency Reuters, China is banning export of minerals like gallium, germanium, and others.
“In principle, the export of gallium, germanium, antimony, and superhard materials to the United States shall not be permitted,” the ministry said.
