Here are global tech companies that have suspended business with Huawei after U.S. ban

Global technology companies, including chip suppliers, are cutting off their ties with China’s Huawei Technologies Co after the Trump administration put the world’s largest telecom equipment maker on a trade blacklist, citing national security concerns.

The government has effectively banned U.S. firms from doing business with Huawei, escalating the ongoing trade war.

However, Huawei has been allowed to buy U.S. goods until Aug. 19 to maintain existing telecoms networks and provide software updates to its smartphones.
