Representatives from China and Myanmar - the two MRC dialogue partners, development donors, and international organizations will also attend the event.
The summit aims to realize MRC commitments to trans-national cooperation on sustainable development of water resources and improved utilisation of natural resources of the Mekong River region in the context of a rising demand for water, energy and food and the impact of global climate change on the region.
The event provides MRC leaders a forum to display their determination to overcome all difficulties and challenges in the MRC River Basin to achieve sustainable development.
The summit will announce prioritised fields in MRC activities in the coming time, especially in ensuring water resources, energy and food security in the context of climate change.
MRC leaders are expected to issue a joint declaration at the meeting.
Prior to the summit, an international conference will be held on April 2-3 to discuss regional and international hot issues such as water resources, energy and food security, risk management and climate change adaptation.
