ADB also helped improve the Louangphrabang Airport in the Lao People's Republic and rehabilitate regional airports in Afghanistan.

"The number of foreign visitors to Lumbini is rapidly rising in the recent years, and airport improvement will help in further opening Lumbini and linking it with international tourist circuits in South Asia as well as to the rest of the world." ADB has also worked to help countries effectively partner with private companies in developing safe and secure air transport system.
Some of the expertise from that work is captured in the publication, Developing Best Practices for Promoting Private Sector Investment in Infrastructure: Airports and Air Traffic Control.Many small Pacific countries have limited resources to develop air traffic control systems, airport operations and technical skills for pilots and ground personnel.With the support of ADB, countries in the Pacific - specifically Fiji, Kiribati, Papua New Guinea, Samoa, Solomon Islands, Tonga, and Vanuatu - established a Pacific Aviation Safety Office (PASO) that allows resources and expertise to be pooled. ADB has been working with governments around Asia and the Pacific to keep people safe in the air.The safety and security of commercial aviation is one of the most complex activities that a country must undertake.This includes improving the safety standards of the facility."Airport upgrading is critical to further developing nearby Lumbini, the birth place of Lord Buddha, into an attractive cultural and tourism destination," said Kenichi Yokoyama, ADB's Country Director for Nepal.Some of the information accumulated by ADB's work has been captured in the publication, Oceanic Voyages: Aviation in the Pacific, which offers a detailed analysis of the Pacific aviation market, including regional and international trends influencing the development of aviation in the region.In Nepal, where mountainous terrain creates many isolated communities and tourism is a vital driver of the economy, air transport is critical.Aviation forms an important part of the transport system all over the world (Antwerpen, 2007).It has been a recognized field where developments have taken place and have brought significant changes making this transport system better than others.
