Officials from China, Thailand, Laos and Myanmar have agreed to cooperate on law enforcement on the Mekong river, where 13 Chinese sailors were killed earlier this month.
Chinese Public Security Minister Meng Jianzhu said after a meeting Monday that officials from the countries would set up a mechanism for joint patrols on the river and share intelligence information.
Nine Thai soldiers surrendered Friday as suspects in the murders of the 13 Chinese near the Thai-Myanmar border. They asserted their innocence.
The Chinese sailors were killed after two cargo ships on the Mekong River were hijacked in early October. Drug smugglers were suspected after Thai authorities found about 920,000 methamphetamine pills on one boat.
