The United States and Qatar also signed a statement of defense cooperation. No additional details, such as the text of the documents, were released immediately.

With US president Donald Trump watching, the chief executives of Boeing and Qatar Airways signed a deal under which the Doha-based airline will purchase as many as 210 Boeing 787 and 777X widebody jets.

Qatar Airways will buy 210 jets from Boeing, the companies announced Wednesday during President Donald Trump’s visit there, as Trump is expected to accept a $400 million jet from the country, despite bipartisan criticism of security and conflict-of-interest concerns.
