Word has spread in a Huawei app forum that Huawei HiSilicon’s chairman He Tingbo and ??? ??? ??? ??? ??Huawei Terminal Business Group’s chairman Yu Chengdong issued an internal letter “To Comrades” in which a contingency plan entitled “Tashan Battle” for PC chipsets was revealed. The letter allegedly urged HiSilicon and the Terminal Business Group to bring about swift and high-quality launches of PC products equipped with the self-developed Kirin X series chipset by the end of the year. In response to an inquiry by a Cailianpress reporter on Thursday, Huawei staff said that no such internal document had been received. On Tuesday, the US revoked licenses allowing Huawei to buy PC-related chips from Qualcomm and Intel, according to overseas media, a move that will further tighten export restrictions on the Chinese telecom equipment maker.
