China has plans to force foreign-made chips out of its telecom systems, according to a report from The Wall Street Journal. The country’s officials reportedly told its telecom providers to replace foreign chips, such as those made by Intel and AMD, by 2027.

Under the order from China’s Ministry of Industry and Information Technology, telecom providers will have to check their networks for any foreign-made chips and then create a timeline for their removal. This change will mainly affect Intel and AMD, sources tell the WSJ, as the two California-based companies provide the “bulk” of the processors included in China’s networking equipment.

Even if they aren’t, China’s purported plan to phase out foreign chipmakers from telecom equipment could take a chunk out of Intel and AMD’s revenue. As noted by the WSJ, Intel made 27 percent of its revenue from China in 2023, while AMD took in 15 percent from sales in the country last year.
