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.

Boeing’s shares surged to the highest level in nearly 13 months after the US aerospace manufacturer secured a record-breaking $96 billion (€85.8 bn) order with Qatar Airways. The deal marked another major agreement struck by President Trump with a Gulf state during his Middle East tour.

Qatar awarded a contract for up to 210 new wide-body civilian airliners to Boeing on Wednesday, a blockbuster deal for the beleaguered aerospace company that was inked in a Doha ceremony where President Donald Trump hailed it as evidence of his abilities to promote U.S. economic interests overseas.
