AH meaning in International ?

The Asian Highway Network (AH), also known as the Great Asian Highway, is a cooperative project among countries in Asia and Europe and the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP), to improve the highway systems in Asia. It is one of the three pillars of the Asian Land Transport Infrastructure Development (ALTID) project, endorsed by the ESCAP commission at its 48th session in 1992, comprising Asian Highway, Trans-Asian Railway (TAR) and facilitation of land transport projects.

Agreements have been signed by 32 countries to allow the highway to cross the continent and also reach to Europe. Some of the countries taking part in the highway project are India (Look-East connectivity projects), Sri Lanka, Pakistan, China, Iran, Japan, South Korea, Nepal and Bangladesh. Most of the funding comes from the larger, more advanced Asian nations like South Korea, India, Taiwan, Japan and China as well as international agencies such as the Asian Development Bank.

The project aims to make maximum use of the continent's existing highways to avoid the construction of newer ones, except in cases where missing routes necessitate their construction. Project Monitor, an Asian infrastructure news website, has commented that "early beneficiaries of the Asian Highway project are the planners within the national land transport department of the participating countries [since] it assists them in planning the most cost-effective and efficient routes to promote domestic and international trade. Non-coastal areas, which are often negligible, are the other beneficiaries."

However, in the mid-2000s some transportation experts were sceptical about the viability of the project given the economic and political climate in both South and Southeast Asia.
