SHENZHEN, China (Aug 18): Huawei Technologies' chairman said while U.S. sanctions have choked its smartphone business, it will not give up and plans to eventually return to the industry's "throne". In 2019 former U.S. President Donald Trump accused Huawei of being a threat to national security, put it on an export blacklist and barred it from accessing critical technology of U.S. origin, affecting its ability to design its own chips and source components from outside vendors.
