After the Chinese government reportedly told domestic airlines not to purchase new planes from Boeing, one jet had to be returned to the U.S. from a facility near Shanghai.

A Boeing jet earmarked for China was returning to the United States on Friday, flight tracking data showed, as the planemaker's flagship delivery plant outside Shanghai was drawn into a deepening tariff war between Beijing and Washington.

A Boeing aircraft wasn't delivered to a Chinese airline as scheduled this week, sparking concerns about the trade war.
