A day after President Trump concluded his visit to Beijing, China confirmed a deal to buy U.S. airplanes and related equipment, in a move that could benefit aircraft maker Boeing (BA) and engine developer General Electric (GE).

Boeing says China has committed to 200 aircraft, reopening a key market but leaving aircraft mix and timing unclear.

Boeing CEO Kelly Ortberg says a potential deal for hundreds of jets is dependent on Trump-Xi negotiations as corporate leaders travel to China.
