Vietnamese authorities have charged Australian resident Tran Hiep, Norwegian-Vietnamese national Nguyen Duc Thuan, and a third man named Thai Cong Truong Son with illegal entry and plotting terrorist activities. The arrests follow the disappearance of Tran and Nguyen after they traveled from Bangkok to Cambodia on September 15. The pro-democracy group Viet Tan strongly disputes the charges, accusing Hanoi of orchestrating an illegal cross-border abduction in an act of transnational repression.
Arrest and Terrorist Conspiracy Charges in Tay Ninh Province
According to a statement released by Vietnam’s Ministry of Public Security, the Security Investigation Agency detained the three men at the border in Tay Ninh province on September 18. State media reports indicate that the suspects allegedly confessed to being members of Viet Tan—an organization designated as a terrorist group by the Vietnamese government—and admitted to using forged documents to enter the country to carry out sabotage and terrorist activities. The ministry initiated a formal criminal case against the men, though officials have not yet announced a date for court proceedings.
Dispute Over Border Crossing and Accusations of Transnational Repression
The official account stands in stark contrast to claims made by Viet Tan and family members. Dr. Phong Nguyen, a representative for Viet Tan, stated that Tran and Nguyen were visiting Cambodia and never intended to cross into Vietnam. According to Viet Tan, the men were last heard from on September 18 while traveling in the southern border district of Kaoh Andaet in Cambodia, and were scheduled to fly back to Bangkok the following morning.
Chloe Dang, the wife of Hiep Tran, told the Australian Broadcasting Corporation that her husband had been meeting pro-democracy activists in Cambodia and was supposed to meet her in Bangkok to catch a return flight to Australia. Viet Tan denounced the detention as “a blatant fabrication intended to conceal the fact that the Viet Tan members were abducted in Cambodia and forcibly taken to Vietnam.” Phil Robertson, Director of Asia Human Rights and Labor Advocates, characterized the operation as an unacceptable outrage and an example of transnational repression in Southeast Asia.

Consular Response and Fair Trial Concerns
Australian Prime Minister Anthony Albanese confirmed that the Australian government is providing consular support to Tran’s family, stating that officials will continue direct engagement. A spokesperson for the Department of Foreign Affairs and Trade noted that the agency is making urgent inquiries with Vietnamese authorities. Meanwhile, representatives for Viet Tan expressed deep skepticism regarding the integrity of the judicial process. Dr. Nguyen warned that defendants in similar politically sensitive cases frequently face predetermined charges and closed-door proceedings, raising serious concerns over whether the accused men will receive a fair trial under Vietnamese law.
