An Australian woman of Vietnamese origin was sentenced to 20 years in prison Tuesday for trying to smuggle heroin in her underwear, local media reported.
Lam Thi Kim Hong Hanh, 38, was caught with 376 grams (13 ounces) of the drug at Ho Chi Minh City's Tan Son Nhat airport in December last year, the Cong An Nhan Dan newspaper reported on its website.
Hanh told the court she was planning to transport the drugs from Vietnam to Australia for a fee of AUS$5,000 ($3,480).
The court in the southern Vietnamese city "sentenced her to 20 years imprisonment for the charge of illegal transport of drugs", the Cong An Nhan Dan said.
Vietnam has some of the world's toughest drug laws. Anyone found guilty of possessing more than 600 grams (20 ounces) of heroin, or more than 20 kilos of opium, can face the death penalty.
The "Golden Triangle" region covering part of Myanmar, Laos and Thailand was once the world's top source of opium but has been overtaken by Afghanistan.
Vietnam has sentenced dozens of foreigners to death for drug offences -- many of them Australian nationals of Vietnamese origin -- but it has been decades since a foreign national was executed in the country.
The Vietnamese government also enforces compulsory "rehabilitation" programs for the country's estimated 140,000 drug addicts.
Despite the harsh sentencing, drug smuggling and use is still commonplace.
In July police arrested 17 people after a blitz on drug crime uncovered major stashes of heroin, cannabis and precursor chemicals.
