President Donald Trump announced on Wednesday a $200 billion deal between Qatar Airways and Boeing, a lifeline for the beleaguered American aerospace giant and a powerful symbol of the diplomatic maneuvering defining his presidency.

The order, Boeing's largest ever for its wide-body jets, deepens ties between the US aerospace giant and the giant Middle East carrier.

A year after Boeing Co. slogged through a deep executive shakeup and prolonged existential crisis, the US planemaker just landed its biggest-ever aircraft order, propelled by a powerful endorsement from President Donald Trump.
