The U.S. and Mongolia have come to terms on an open-skies civil aviation agreement.
Under a memorandum of understanding, airlines from each country would be able to fly without restrictions between the two nations. In addition, carriers from each country would be allowed to overfly the other nation.
Airlines from the two countries could also enter into codeshare agreements.
The memorandum of understanding must still be ratified in each country before taking effect. To date, the U.S. has open-skies agreements in place with more than 130 nations, the State Department said.
Currently, no carrier flies between the U.S. and Mongolia.
