The Asian Highway Network (AH), also known as the Great Asian Highway, is a cooperative project among countries in Asia and the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) to improve their connectivity via highway systems. 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 (Act East policy), Sri Lanka, Pakistan, China, Iran, Japan, South Korea, Nepal and Bangladesh. Most of the funding comes from the larger, more advanced Asian nations such as China, South Korea and Singapore as well as international agencies such as the Asian Development Bank (ADB) and the Asian Infrastructure Investment Bank (AIIB).
