Supercomputing is latest front in U.S.-China high-tech battle

China’s burgeoning supercomputer industry became the latest target of U.S. trade restrictions as officials banned shipments to four Chinese technology companies and one research institute on the grounds that they threaten American national security.

This latest move in a broadening confrontation over advanced technology between the world’s leading economies appeared in a notice to the Federal Register dated Tuesday, which became public Friday. The move comes after last month’s similar move against Chinese telecommunications manufacturer Huawei Technologies, which U.S. officials placed on its “Entity List” over allegations it violated sanctions against Iran, among other national security issues.
