China on Friday launched an investigation into FedEx for "failing to deliver express packages" to the correct addresses in the country, state media said, after the US delivery service misrouted some Huawei parcels.
FedEx apologised earlier this month for the delivery mishap after Chinese telecoms giant Huawei said it was reviewing its ties with the package service over the incident.
The US delivery firm said at the time that "no external parties requested that FedEx transfer these packages".
"China's relevant government department has started an investigation into FedEx, delivering a notice of inquiry to FedEx China on Friday," reported Chinese official news agency Xinhua on Friday, without specifying which department.
Beijing's investigation into FedEx comes as Huawei faces moves from the US to blacklist the Chinese tech firm, cutting it off from American-made components it needs for products -- though it was issued a 90-day reprieve in May.
China hit back last month by announcing it would create its own blacklist of "unreliable" companies and individuals amid escalating tensions in the US-China trade war.
