TAIPEI -- The U.S. government on Friday further tightened export controls on Huawei Technologies' access to American equipment and software, a move designed to restrict access by China's biggest tech company to vital semiconductor supplies.
Any foreign chipmakers producing chips from designs by Huawei and its affiliates with the use of American design tools or equipment will have to apply for a license from the U.S. Commerce Department, the department said on its website.
