US-based Micron Technology forecast a single-digit hit to revenue after a ban by China on sale of its memory chips to key domestic industries marked the latest in the Sino-American trade spat.

China’s cyberspace regulator said late on Sunday that Micron, the biggest US memory chipmaker, had failed its network security review and that it would block operators of key infrastructure from buying from the company.
