Beijing authorities will investigate FedEx for allegedly “undermining the legitimate rights and interests” of Chinese clients, the official Xinhua news agency reported on Saturday, less than 24 hours after China’s commerce ministry said it would compile a list of “unreliable” foreign companies.

Xinhua said FedEx had not delivered packages to their intended recipients in China in violation of “laws and regulations governing the express industry in China”.

The agency did not identify the FedEx clients involved or say what penalties the US delivery company could face. Last week, however, Huawei said FedEx had diverted packages sent from Japan to the US rather than to its offices in China. FedEx is reported to have apologised for what it said was an error.
