The United States and Mongolia will sign an “Open Skies” civil aviation agreement, U.S. Vice President Kamala Harris and Mongolian Prime Minister L.Oyun-Erdene said.

Washington has Open Skies civil aviation agreements with more than 130 countries. They grant airlines from both countries the right to operate in each other’s countries, liberalize airline regulation and impose safety and security standards.

The Open Skies deal between the U.S. and Mongolia will build on a memorandum of understanding for an air transport agreement reached in January.

Mongolia’s national carrier, MIAT Mongolian Airlines, flies to Europe and Asia but not the United States at present. Although passenger demand may not merit nonstop flights between the Mongolian capital, Ulaanbaatar, and the U.S., the Open Skies deal would also provide easier options for cargo flights between the nations.
