# Chinggis Khaan International Airport

Chinggis Khaan International Airport (IATA: UBN, ICAO: ZMCK), also referred to as New Ulaanbaatar International Airport, is the primary airport serving Ulaanbaatar, and is Mongolia's only international airport. It opened on 4 July 2021, replacing Buyant-Ukhaa International Airport.
It is the largest air facility in the country, serving as a hub for all major Mongolian airlines, and is located in the Khöshig Valley of Sergelen, Töv Province, 52 km south of Ulaanbaatar and 20 km southwest of Zuunmod. The airport is connected via highway to Ulaanbaatar, with shuttle bus routes operating to and from various points in the city. It features direct flights to 11 domestic destinations and various international destinations in Asia and Europe.
In 2024, it served over 2.1 million domestic and international passengers.

## History
### Origin

Ulaanbaatar's former main airport, Buyant-Ukhaa International Airport, established in 1957, is located in close proximity to two mountains to its south and east, so only one end of its runway was able to be used, and was often adversely affected by weather events. The new airport was designed with a capacity of handling up to 1,100 passengers per hour and three million passengers per year, with cargo capacity set at 11,900 tons. Its development was majority funded by a Japanese government (JICA) soft loan (93%), with the rest provided by the Mongolian government.

### Development

Initial planning for the airport was done in 2006 with Japanese government assistance. In May 2008, a ¥28.8 billion (US$385 million) 40-year soft loan agreement at 0.2% interest was signed between the Government of Mongolia and the Japan Bank for International Cooperation to build a new international airport. The loan required that the project is to be carried out by Japanese consultants and contractors; however, the materials and equipment the contractors use could be up to 70% from any country. Between 2009 and 2011, Azusa Sekkei and Oriental Consultants Joint Venture made the design and bid documentation for the airport. In 2011, a call for bids was announced for the construction of the airport, with the Mitsubishi-Chiyoda Joint Venture (MCJV) successful in the technical bidding. An extended price review and contract negotiation were completed on 10 May 2013 when the main construction contract was signed between MCJV and the Civil Aviation Authority of Mongolia. The final amount of loans from the Japanese Government for the development of the airport totaled ¥65.6 billion (US$600 million), to be paid over forty years.

### Construction and opening

The groundbreaking ceremony was on 22 April 2012, with initial construction starting with a site flood-protection scheme. Other works under way included the construction of the electric power line from Nalaikh. Main construction lasted from May 2013 to April 2020. The concrete pouring work for the control tower started on 13 September 2013. On 29 January 2014, the airport's electric substation construction was completed and connected to the Mongolian central grid. Construction of a six-lane, 30 km-long highway to Ulaanbaatar started in May 2016, and ended in 2019.
While the initial opening date was slated for December 2016, the bulk of construction only ended in 2017. Opening of the airport was repeatedly delayed to 2018, 2019, 2020, and 2021. These delays were related to contract negotiations regarding the operation and ownership of the airport, the construction of the highway to Ulaanbaatar, and the impact of the COVID-19 pandemic in Mongolia.
Operations at the airport started on 4 July 2021, with an inaugural flight to Tokyo operated by MIAT Mongolian Airlines, flying Ulaanbaatar-Narita-Ulaanbaatar with a Boeing 737.
The airport was referred to by various names during its planning and construction phases, including New Ulaanbaatar International Airport and Khöshig (or Khöshigt) Valley Airport. The new airport was given its current name on 2 July 2020, with the former Chinggis Khaan International Airport reverting to its pre-2005 name of Buyant-Ukhaa International Airport. Chinggis Khaan is a transliteration of the modern Mongolian pronunciation of Genghis Khan.
In July 2024 Nippon Koei was contracted to perform an assessment regarding the expansion of the airport.
