China bans AMD, Intel, and Microsoft products from government computers

China has banned the use of AMD and Intel processors in government computers and servers.

New rules also block Microsoft Windows and foreign database products, replacing them with domestic alternatives.

Approved domestic processors include chips from Huawei and Phytium, which are banned in the US.

The bans could significantly impact Intel and AMD revenue - China accounted for 27% of Intel's sales and 15% of AMD's last year.

The moves are China's most aggressive yet to restrict the use of US-built technology, amid a long-running tech trade war between the two countries.
