Huawei’s revenue grew by 19.1 percent last year to around $121 billion, but the company says those numbers would be far higher if the United States had not cracked down on its ability to do business. Due to a trade ban initially ordered last May, Huawei is unable to acquire US parts and software or sell its products in the US. That has cut the company out of an important market and hurt its ability to compete outside of China.
