The Biden administration is considering cutting off Huawei Technologies Co. from all of its American suppliers, including Intel Corp. and Qualcomm Inc., as the US government intensifies a crackdown on the Chinese technology sector. Sales from US firms to Huawei have been limited for four years, since former President Donald Trump added the Shenzhen, China-based company to the so-called US “entity list” out of national security concerns. US suppliers have since required government approval to sell to the telecom equipment giant.
