Boeing Co. has found itself at the center of the raging trade war between the U.S. and China, with the latter reportedly instructing its airlines to halt deliveries of the U.S.-made jets.

Boeing stock fell after China ordered its airlines to halt deliveries of the company’s jets as part of an escalating trade war with the U.S., according to a report. Chinese airlines have been told not to accept any more Boeing deliveries and asked that carriers not buy any further aircraft-related gear from U.

The stock fell as much as 3% as Bloomberg reported China halted all purchases of US aircraft.
