When China and the leaders of nations along the Mekong River meet on Wednesday at the Lancang-Mekong Cooperation summit in Cambodia, a top item is to be mapping out a five-year development plan that would include building hydropower dams and other projects for the region - pointing to its importance in China's ambitious Belt and Road infrastructure plan.
In recent months, Kem Monovithya has attended a panel meeting with the USA and European Union permanent missions to the United Nations, where she requested that Cambodia's seat at the world body be withheld, called for economic sanctions against Cambodia's government, and requested visa restrictions be put in place to punish Cambodian officials responsible for curbing democracy in the country. China is Cambodia's biggest source of aid, investment and imports.
Leaders of the six riparian countries held their first meeting in China in 2016 and the next summit is to take place in Laos in 2020.
The Lancang-Mekong Cooperation was established by Beijing in 2015.
