The Vientiane International Airport Terminal Expansion Project has been completed, aimed to accommodate the rapidly increasing air traveller demand; improve airport convenience, efficiency and safety; and contribute to the long-term economic development of Laos.

The project, supported by the Japan International Cooperation Agency (JICA) with the Japanese ODA loan, included expansion of the international passenger terminal, construction of a new domestic passenger terminal and other works at the Wattay International Airport in Vientiane, the capital of Laos.

As the gateway to the country, the airport has reportedly seen a rise in the number of tourists. It is estimated that the number of travellers using the airport will increase from 690,000 (international) and 300,000 (domestic) in 2014 to 1.51 million and 460,000, respectively, by 2023.

In 2014, JICA signed a Japanese ODA loan agreement for 9.017 billion yen for the project, and has assisted in the expansion of the international passenger terminal, construction of the new domestic passenger terminal building, and development of peripheral facilities (such as parking facilities, roads and taxiways).

The project was carried out under a public-private partnership with Toyota Tsusho Corporation and Jalux Inc, which are involved in a management and operation project for the airport.
