KUNMING -- The 162nd joint patrol of the Mekong River by law enforcement authorities from China, Laos, Myanmar and Thailand concluded on Friday, having formed part of efforts to safeguard this vital waterway during the busy Spring Festival period.

The operation lasted five days and four nights, covering a distance of over 700 km. A total of 101 law enforcement officers and five vessels from the four countries participated in the mission.

The patrol took place during the peak shipping season and the river's dry period. Aiming to address a complex security situation and the high risk of navigation accidents, such as running aground and reef strikes, the joint formation focused on high-risk waters.

During the operation, the formation conducted land and water inspections, checking more than 50 vessels, over 200 individuals and 5,000 tonnes of cargo. Officers also provided safety tips and rescued a merchant ship in distress, effectively maintaining order and safety along the river.

Since its launch in December 2011, this joint patrol mechanism has played a crucial role in maintaining regional stability. The Mekong River, known as the Lancang River in China, remains a key channel for cross-border shipping between these four nations.
