(Reuters) - Global technology companies are cutting ties with China's Huawei Technologies Co Ltd after the U.S. government put the world's largest telecom equipment maker on a trade blacklist, citing national security concerns.
The United States has effectively banned its companies from doing business with Huawei, exacerbating an ongoing Sino-U.S. trade war. The ban applies to goods that have 25% or more of U.S.-originated technology or materials, and may affect non-American firms.
Huawei is allowed to buy U.S. goods until Aug. 19 to maintain existing telecoms networks and provide software updates to its smartphones.
