SHENZHEN, China, May 31 (Reuters) – For the ambitious Chinese tech entrepreneur, expanding into the U.S. just keeps getting harder.

Before 2019, there were few major impediments to having a Chinese company that did business in the U.S. from China. But amid escalating U.S.-Sino trade tensions, particularly after Washington slapped sanctions on telecom giant Huawei (HWT.UL), some Chinese firms began setting up headquarters overseas – moves that could help them draw less U.S. government attention.
