A pilot with FedEx was arrested by authorities in China in the latest setback for the US logistics company in the country, where it has been under a series of investigations against the backdrop of a simmering trade war between Washington and Beijing. “FedEx confirms that Chinese authorities in Guangzhou detained and later released one of our pilots on bail after an item was found in his luggage prior to a commercial flight,” it said. FedEx did not identify the pilot or the nature of the item.
