TAIPEI -- Shares in key Asian suppliers to Huawei suffered sharp falls on Tuesday after the U.S. government further broadened its clampdown on the Chinese tech champion, forbidding non-American companies from supplying it with any chips based on U.S. technology.
MediaTek, the mobile chip designer, plunged more than 9% at the Taiwan Stock Exchange. The company, the world's second-largest mobile chip supplier, is seen as one of the crucial mobile chip suppliers for Huawei's smartphone business. It also sells chips to other smartphone makers including Samsung Electronics, Oppo, Vivo and Xiaomi.
