The chairman and CEO of long-haul airline Emirates says he's not worried about the next U.S. president being more protectionist amid an ongoing row with American carriers.

Speaking to journalists Tuesday, Sheikh Ahmed bin Saeed Al Maktoum said "different governments come and go," but it won't have much of an effect. He also said that airlines should negotiate disputes with the government, not between themselves.

U.S. carriers, including American, Delta and United, have criticized what they say are billions of dollars in subsidies to Gulf carriers. They are pressing Washington to reconsider treaties that allow Gulf airlines to fly to the U.S.

Emirates, although owned by Dubai's sheikh-ruled government, vigorously denies receiving state subsidies.
