Boeing Co said on Wednesday it had won orders and commitments from China for 250 narrowbody 737 aircraft and 50 widebody aircraft, valued at about $38 billion at list prices.
The order, announced as Chinese President Xi Jinping toured Boeing's Everett, Washington, factory, includes some planes that were previously ordered but for which the buyers had not been identified. Boeing declined to say how many planes had been previously ordered, leaving uncertainty about the total value.
Boeing's shares were down 1.5 percent at $131.95 in afternoon trading in New York.
