The Qatar-Boeing deal is the latest in a series of high-profile aviation agreements signed during Trump’s four-day Middle East visit. Just a day earlier, Saudi Arabia’s sovereign wealth fund inked a $4.8 billion agreement with Boeing, and U.S. Commerce Secretary Howard Lutnick announced a $10 billion order from a British airline.

Boeing's business has been beset by issues and disrupted by Trump's trade war with China, which stopped accepting plane deliveries in response to U.S. tariffs.

The United States and Qatar inked economic deals worth more than $243.5 billion, laying the groundwork for a bigger $1.2 trillion package of expanded investment and trade, the White House said.
