Whatever the reason, it is a big problem for Huawei which has had some difficulty getting its foot in the door in the US. Best Buy was one of Huawei's biggest retail partners, and one of the rare places where you could physically see its phones.

Huawei phones aren't sold by any US carriers, where a majority of Americans typically buy their phones. In 2012, the House Intelligence Committee released a report accusing Huawei and fellow Chinese vendor ZTE of making telecommunications equipment that posed national security threats, and banned US companies from buying the gear.

At the time, the committee stressed that the report didn't refer to its smartphones. But since Trump took office the directors of the FBI, CIA and NSA all expressed their concerns about the risks posed by Huawei and ZTE phones.

We wonder if the move will affect Best Buy's Chinese shops (pictured).
