Thailand's flood disaster will be high on the agenda as Southeast Asian nations gather on the Indonesian island of Bali for the annual ASEAN conference.
Members are expected to agree to greater co-operation when it comes to flood prevention.
But many businesses and citizens in Thailand say they have been let down by the government, as Al Jazeera's Wayne Hay reports.
Many Thais are arguing that the economic and social impact of the long-running flood has been made worse by miscommunication and a lack of co-ordination from government agencies.
