The Lancang-Mekong Cooperation Mechanism is seen as a big step in forging good relationships with its neighbors. CGTN's reporter Han Bin went to Laos to see how the policy is reshaping the life of people living along the river.

The "golden waterway" for trade. The Mekong, known as the Mother of All Rivers, provides life-sustaining resources to millions. Trade is expanding, and changes are taking place.

HAN BIN LAOS "The Mekong links China and five other states, carrying potential for growing economies through border trade, cultural exchange and infrastructure projects. That's the driving factor in China's moves for economic integration through transport linkage."

And this region may well hold the biggest opportunity for growth. Ever since 2011, joint law enforcement has been carried out by China, Myanmar, Laos and Thailand. The aim is to boost stability, and access to trade. This monthly patrol, which crosses the borders of participating countries, is seen as a diplomatic effort in strengthening regional security and economy. Here, at Guanlei Port, China's gateway to the Mekong, transport businesses are growing year by year. China mainly imports timber, rubber and mineral ore from Southeast Asia, and exports commodities and daily necessities. Li Guolin may know the river better than anyone else. He's been a ship's captain on the Mekong for 15 years. This cargo of timber is coming from Laos. His ship can carry some 200 tons of goods each time. He says business is closely linked with the safety on the route, and China's relations with the neighboring countries.

Li's biggest concern is this stretch, which is difficult to navigate. Reefs and rapids are everywhere. A controversial plan to widen the passage gained consensus. South China Sea disputes have strained relations in the neighborhood. The Mekong River is a testing ground for proactive diplomacy based on shared interests and mutual benefits. China says the aim is to strengthen not only security but also access to trade.
