Customs officers at Ho Chi Minh City's Tan Son Nhat Airport said they seized 23 DVDs containing anti-state information from a Vietnamese passenger aboard a flight from Singapore to Vietnam on Friday evening.
Tran Song Hai, 39, had the DVDs in his hand luggage that was inspected on his arrival from Singapore.
The custom officers said the discs contain defamatory material and calls for war, violating Vietnamese laws.
The passenger and the DVDs were handed over to local authorities for further investigation.
Under Vietnamese law, those who produce, store and distribute anti-state propaganda could be sentenced to between three and 12 years in jail.
