Huawei Is the world's largest telecommunications equipment maker. Last year, Trump administration placed Huawei on the entity list, then U.S. Commerce Department made a big change to its export rules. Under those rules, Foundries that make semiconductors using U.S. technology would no longer be allowed to sell chips to Huawei without obtaining a license. Huawei has been named a national security threat and a U.S. Department of Commerce spokesman says that America's licensing policies continue to "restrict Huawei's access to commodities, software, or technology for activities that could harm U.S. national security and foreign policy interests." Which is why huawei couldn’t get new Kirin chips or any modern chips to use inside its smartphones.
According to Reuters, the the U.S. has granted licenses authorizing suppliers to sell chips to Huawei for vehicle parts business. It doesn't cover chips for smartphones or 5G networks. Will the U.S. commerce department slowly allow Huawei to get its smartphone chips from manufacturers again? Only Time will tell.
