The National Dialogue on Water in Thailand was initiated in 2021 under the regional initiative with the Ministry of Environment of the Republic of Korea (MoE), the Asia Water Council (AWC) and the OECD. The Dialogue covers two main topics selected by the Government of Thailand (ONWR). The first one is water demand management, with a focus on the Eastern Economic Corridor. The second one is financing water supply and sanitation. Both combine to support a sustainable and resilient development pathway for Thailand’s fast-growing economy.
