Border guards in the northern province of Quang Ninh on Saturday arrested a woman who allegedly attempted to cross the China border to smuggle nearly four kilograms of meth.
Patrol officers at a station around Mong Cai border gate caught Nguyen Thi Ha, 33, at around 4 am.
Ha allegedly hid 18 small bags of crystal that she admitted to be methamphetamine in two bigger bags labelled as Chinese confectioneries.
The local of Ha Giang Province, which also borders China, said a Chinese man named Zhou hired her to deliver the drug.
Ha said Zhou offered to pay her VND20 million (nearly US$1,000) to deliver the bags to a Vietnamese man named Bao in the resort town of Ha Long in Quang Ninh. She had received half of the money upfront.
Further investigations are underway.
Vietnam has some of the world's toughest drug laws. Those convicted of smuggling more than 600 grams of heroin or more than 2.5 kilograms of methamphetamine face the death penalty.
The production or sale of 100 grams of heroin or 300 grams of other illegal narcotics is also punishable by death.
