China has introduced guidelines that bar the the use of US processors from AMD and Intel in government computers and servers, The Financial Times<\/em><\/a> has reported. The new rules also block Microsoft Windows and foreign database products in favor of domestic solutions, marking the latest move in a long-running<\/a> tech trade war between the two countries.<\/p>\n Government agencies must now use “safe and reliable” domestic replacements for AMD and Intel chips. The list includes 18 approved processors, including chips from Huawei and the state-backed company Phytium \u2014 both of which are banned in the US.<\/p>\n The new rules \u2014 introduced in December and quietly implemented recently \u2014 could have a significant impact on Intel and AMD. China accounted for 27 percent of Intel’s $54 billion in sales last year and 15 percent of AMD’s revenue of $23 billion, according to the FT<\/em>. It’s not clear how many chips are used in government versus the private sector, however.<\/p>\n The moves are China’s most aggressive yet to restrict the use of US-built technology. Last year, Beijing prohibited<\/a> domestic firms from using Micron chips in critical infrastructure. Meanwhile, the US has banned a wide range of Chinese companies ranging from chip manufacturers to aerospace firms. The Biden administration has also blocked<\/a> US companies like NVIDIA from selling AI and other chips to China.<\/p>\n The US, Japan and the Netherlands have dominated the manufacturing of cutting-edge processors, and those nations recently agreed to tighten export controls<\/a> on lithography machines from ASL, Nikon and Tokyo Electron. However, Chinese companies, including Baidu, Huawei, Xiaomi and Oppo have already started designing their own semiconductors<\/a> to prepare for a future wherein they could longer import chips from the US and other countries<\/a>.<\/p>\n<\/div>\n
