Shares of Intel (INTC) and Advanced Micro Devices (AMD) tumbled Friday morning on a report that China has told its telecom companies to phase out chips made outside the country, including those by American companies.

The Wall Street Journal said the order from the Ministry of Industry and Information Technology earlier this year directed China’s biggest telecoms to elimin💛ate foreign processorsဣ that are core to their networks by 2027.

The move was aimed at accelerating the country’s effort to cut out those chips, and the Ministry instructed state-owned mobile operators to inspect their networks for non-Chinese 澳洲幸运5开奖号码历史查询:semiconductors and put together timelines to replace the𓆏m, according to the report.

People familiar with the matter told the Journal the decision would affect Intel and AMD the hardest, since the two U.S. firms have p🧔rovided the bulk of the core processors used in China and the world in recent years. 

Neither Int🐠el nor AMD immediately responded to requests fo🅰r comment.

Intel shares were down 3.6% at $36.28 as of about 11:45 a.m. ET, while AMD was off 3.8% at $163.96.
