BANGKOK, Dec. 18 (Xinhua) -- Chinese and Thai companies signed three documents on Monday at northern Thailand's Chiang Saen port in a bid to develop boat trip service along the Lancang-Mekong river.

"The joint patrol of China, Laos, Myanmar and Thailand make it safe to sail on the Mekong river, making it possible for tourism routes linking these Chiang cities to grow," he mentioned.
