The Lancang-Mekong Cooperation (LMC) has brought tangible benefits to the people in the region and promoted sub-regional cooperation.

Under the framework, a large number of projects have helped enhance cooperation in environmental protection, climate change and sustainable use of resources.

The third LMC leaders' meeting will be held via video link on Aug. 24, according to China's Foreign Ministry.

Initiated by China in 2014, the LMC consists of six countries, namely China, Cambodia, Myanmar, Laos, Thailand and Vietnam.

The Lancang River originates on the Qinghai-Tibet Plateau in southwest China. It is called the Mekong River as it flows through the other five countries before emptying into the sea.
