HONG KONG - Chinese telecoms equipment maker Huawei is reviewing its relationship with FedEx Corp after it claimed the US package delivery company, without detailed explanation, diverted two parcels destined for Huawei addresses in Asia to the United States and attempted to reroute two others.

Huawei told Reuters on Friday that FedEx diverted two packages sent from Japan and addressed to Huawei in China to the United States, and attempted to divert two more packages sent from Vietnam to Huawei offices elsewhere in Asia, all without authorization, providing images of FedEx tracking records.

Reuters could not verify the authenticity of the records. Shown the images of the tracking records, FedEx declined to make any comment, saying company policy prevented it from disclosing customer information.

Huawei said the four packages only contained documents and "no technology," which Reuters was unable to independently confirm.

Huawei declined to elaborate on why it thought the packages were diverted.

"The recent experiences where important commercial documents sent via FedEx were not delivered to their destination, and instead were either diverted to, or were requested to be diverted to, FedEx in the United States, undermines our confidence," Joe Kelly, a spokesman for Huawei, told Reuters.

"We will now have to review our logistics and document delivery support requirements as a direct result of these incidents," the spokesman said.

Huawei acknowledged to Reuters that one package originating in Vietnam was received by Friday, and the other was on its way, according to FedEx tracking records provided by Huawei.

FedEx spokeswoman Maury Donahue told Reuters the packages were "misrouted in error". She acknowledged in an earlier statement that the US Department of Commerce had recently added Chinese companies and affiliates to its "Entity List", but did not elaborate.

FedEx was not requested to divert the packages by any other party, she added.

"This is an isolated issue limited to a very small number of packages," said FedEx, referring to the four parcels affected. "We are aware of all shipments at issue and are working directly with our customers to return the packages to their possession."

FedEx China on Tuesday apologized on its Chinese social media account for the "mishandling" of Huawei packages and confirmed there was no "external pressure" to divert packages.

The US Department of Commerce did not reply to a request for comment on whether the incident might be related to its move on May 16 to add Huawei to the so-called "Entity List," preventing it buying certain items from US companies without US government approval.
