On its most crucial business, namely, its telecoms business (including 5G) and server business, Huawei has stockpiled 1.5 to 2 years' worth of chips and components. It began massively stockpiling from 2018, when Meng Wanzhou, the daughter of Huawei's founder, was arrested in Canada upon U.S. request. Key Huawei suppliers included Xilinx, Intel, AMD, Samsung, SK Hynix, Micron and Kioxia. On the other hand, analysts predicted that Huawei could ship 195 million units of smartphones from its existing stockpile in 2021, but shipments may drop to 50 million in 2021 if rules are not relaxed.
