The U.S. imposed sanctions on Huawei after accusing it of building backdoors into its equipment that could be exploited by the Chinese Communist Party for espionage purposes.
In 2019, Huawei was put on a U.S. blacklist called the Entity List. This restricted American companies from exporting certain technologies to Huawei. Google ended up cutting ties with Huawei, meaning the Chinese giant could not use Google’s Android operating system on its smartphones. Last year, the U.S. moved to cut Huawei off from key chip supplies it needs for its smartphones. Huawei strongly denies the U.S. allegations.
