China has agreed to buy 200 Boeing (NYSE:BA) planes in a deal that could eventually expand to as many as 750 aircraft, President Donald Trump said on Friday, potentially marking the U.S. planemaker’s biggest breakthrough in the world’s second-largest economy in nearly a decade as trade tensions between Washington and Beijing begin to ease.

Speaking aboard Air Force One, Trump told reporters the agreement “includes approximately 200 planes and a promise of up to 750 if they do a good job,” and the jets will be powered by GE Aerospace (NYSE:GE) engines, though details on aircraft types and delivery schedules were not immediately disclosed, according to a Reuters report.

A Boeing spokesperson told Benzinga in an emailed statement that the company expects “further commitments” after the initial orders. “We now look forward to continually addressing China's aircraft demand,” the spokesperson added.

GE Aerospace did not immediately respond to Benzinga‘s request for comment.
