Cambodian Prime Minister Hun Sen flew Friday to Ho Chi Minh City, Vietnam to attend the second Summit of the Mekong River Commission (MRC), which will be held on Saturday.

The premier was accompanied by Minister of Water Resources and Meteorology Lim Kean Hor, Environment Minister Say Samal, and Sok Chenda Sophea, secretary general of the Council for the Development of Cambodia, as well as other members of the government, Sry Thamarong, minister attached to Prime Minister Hun Sen, told reporters at Phnom Penh International Airport before departure.

He said the summit will be held under the theme "Water, Energy and Food Security in the Context of Climate Change for the Mekong River Basin."

"It will be the most momentous event as leaders of the MRC countries -- Cambodia, Laos, Thailand and Vietnam -- revisit their commitments made four years ago on a number of key issues facing the Mekong River Basin," he said.

The summit will also be attended by dialogue partners including China and Myanmar and a number of development partners.

"The heads of the MRC countries will discuss a number of issues on the opportunities and challenges of the Mekong basin and roles of the MRC for sustainable development and regional cooperation to promote sustainable use and development of the Mekong River in the context of growing demand for natural resources for development and of climate change," he said.

According to the MRC, the leaders will discuss, amongst other key priority areas, the best ways in which the MRC can promote its effectiveness and ownership by member countries by 2030 and reinvigorate regional cooperation in the transboundary management of water and related resources ahead of the establishment of an ASEAN economic community by 2015.
