Currently , in a region known as the " Golden Triangle " , river piracy , combined with illegal trafficking of heroin , poses a major international law enforcement problem . One of the worst criminal cases dealing with Asian river pirates occurred on October 5 , 2011 , called the " Mekong River massacre " . A Chinese cargo ship hauling nine hundred thousand amphetamine pills , worth more than three million dollars , was attacked and hijacked , and thirteen crewmen were killed . The hijackers were caught and executed by the Chinese government in 2012
