The CEO of Qatar Airways has called on President Donald Trump to do more to end an economic blockade of his country.

Qatar is locked in a dispute with neighboring countries which has curtailed airspace rights over the nation. The airline's management predicts it will swing to a full-year loss as a result of the diplomatic standoff.

Speaking at the CAPA aviation conference in Singapore, Akbar Al Baker told CNBC Tuesday that the U.S. leader must act faster.

"President Trump is trying to do more, but I think he needs to do even more because he has given an undertaking to my ruler that he will solve the problem and he will solve it soon," he said.

"And we are depending on him," Al Baker added.

The airlines boss said the U.S. had a responsibility to protect Qatar.

"We are an American ally, you have a very large American community in my country. You have important assets and interests in my country. As Americans, you should never allow such a thing to happen to my country," he said.
