China, Laos, Burma and Thailand launched the fifth joint Mekong River patrol on Monday, in an effort to discourage bandits and drug runners in the Golden Triangle area.
The joint patrol set off from Guanlei Port located in Xishuangbanna prefecture in southwest China's Yunnan Province, said a story on Monday by the Xinhua news agency. The patrols started in December 2011.
Senior cabinet members from the four countries met in Beijing last October and agreed to take joint action to crack down on cross-border crime and to secure routes along the Mekong River following the murder of 13 Chinese sailors on the river.
In May, a Burmese national, Naw Kham, a drug lord suspected of masterminding the attack on the Chinese sailors, was arrested in Laos and sent to Beijing for trial.
