China has agreed to ​buy 200 Boeing, U.S. President Donald Trump told Fox News Channel on Thursday, a number that was far fewer than analysts ‌had expected, and the planemaker’s shares fell.

Axar.az reports, citing Reuters, details of the deal were not immediately available, including when and which type of jets would be delivered, but the amount was much smaller than the roughly 500-plane package that sources told Reuters was under discussion ahead of a meeting on Thursday between Trump and Chinese leader Xi Jinping.

"One ​thing he agreed to today, he's going to order 200 jets ... 200 big ones," Trump said on Fox News' Hannity, ​referring to Xi.

Boeing shares fell 4.1% during market trading on Thursday.
