"The package in question was accidentally returned to the sender and we apologize for this operating error," FedEx told Reuters in an e-mail statement. A company spokeswoman confirmed that the package was sent to the US, but declined to say what it contained.
Huawei, the world's largest telecommunications supplier, is at the center of a fierce trade dispute between Washington and Beijing. China initiated a FedEx investigation earlier this month concerning the delivery of Huawei parcels to the wrong address without providing details of the deliveries in question.
China's state-run news agency Xinhua said back then that investigations into misappropriated mail should not be viewed as retaliation against the US company.
The United States and China have been involved in a trade dispute over months, including tariffs, subsidies, technology, regulations and cybersecurity. Washington blacklisted Huawei last month and headed national security.
"FedEx can accept and transport all Huawei products, except for shipments to companies listed in the US entity list," the company said Sunday.
The missed delivery was previously reported by the Chinese Global Times, a tabloid published by the People's Daily of the Communist Party.
On Friday, the US Department of Commerce announced that it is adding several Chinese companies and a national institute dealing with supercomputing with military applications to its list of national security companies, which prohibits them from acquiring US parts and components without Approval of the government to buy.
Huawei, who claimed to check its relationship with FedEx after its packages had previously been maltreated, did not respond promptly to a Reuters request for comment on Sunday.
