One of the packages was intended for PC Magazine in the US, which wanted to review Huawei's latest P30 Pro smartphone.

PC Magazine ask its UK writer to send over the phone from London to its US office in New York, but it was returned to sender, and the magazine was told that the writer was not allowed to do this because of a "US government issue" with Huawei and the Chinese government.

FedEx has apologised, saying that the packages were not delivered due to an "operational error".

It added that it would continue to deliver all products made by Huawei to US addresses, with the exception of Huawei addresses and other partner addresses that had been placed on a US national security blacklist.

This is totally ridiculous. Our UK writer tried to send us his @HuaweiMobile P30 unit so I could check something - not a new phone, our existing phone, already held by our company, just being sent between offices - and THIS happened @FedEx
