1. River restoration is of vital importance to socio‐economic sustainable development inparallel with flood and water use management.
2. Basin is a basic unit for river environment management.
3. Establishing suitable methodological technology for river restoration that suit for Asianmonsoon region is necessary.
4. In Asia monsoon region,g , human‐influence to a cultural landscapep is harmonized with theecosystem traditionally.
5. It is important to develop a database of projects and knowledge of international experts inriver restoration, and this activity should be supported by engineers, scientists, ecologists,managers and public.
6. It is urgent to establish a river restoration guideline suitable for the Asian monsoon region
for countries with similar social and natural conditions.
