SHENZHEN, China (Reuters) - Huawei Technologies [HWT.UL] plans to sell its budget-brand Honor smartphone unit in a 100 billion yuan ($15.14 billion) deal after years of pressure from U.S. trade curbs made on grounds that the technology firm is a national security threat. The world’s biggest maker of mobile telecommunications equipment has repeatedly denied the accusation, but in May this year its rotating chairman acknowledged it was in survival mode.
