KUNMING, May 26 (Xinhua) -- The 129th joint Mekong River patrol by China, Laos, Myanmar, and Thailand concluded on Friday, said the public security department of southwest China's Yunnan Province.
Seven vessels and 135 law-enforcement staff members from the four countries traveled over 500 km during the patrol, which lasted four days and three nights.
The Chinese side also cooperated with law enforcement departments of Laos to conduct land inspections, with more than 50 vehicles, more than 80 personnel, and more than 20 tonnes of goods checked.
