Cambodia has rejected accusations that its authorities detained and handed over an Australian pro-democracy activist and a Norwegian national of Vietnamese origin to Vietnam's communist government. The two men disappeared after entering Cambodia, staying there briefly, and preparing to travel to Bangkok to meet a spouse before returning to Australia.

Who Are the Men?

The Norwegian citizen is Nguyen Duc Thuan, 52, a member of the pro-democracy movement Viet Tan. The Australian is Tran Hiep, 50, who also goes by Ho Pham Hiep Huy. A third man, Thai Cong Trung Son, whose nationality has not been confirmed, was also named. Hanoi has charged all three with terrorism. On September 29, The Guardian reported a Vietnamese statement saying Thai Cong Trung Son had been bringing the other two across the border from Cambodia when authorities arrested all three.

Cambodia's Account

Cambodia's Ministry of Interior said Tran Hiep and Nguyen Duc Thuan, who held Australian and Norwegian passports respectively, were being held in Vietnam. The ministry said the Australian embassy in Phnom Penh asked for help locating Tran Hiep on September 22. The same day, it received word that Nguyen Duc Thuan had lost contact with his family on September 18.

According to the ministry, both men entered Cambodia from Thailand on September 15 through Techo International Airport on flight K6 723. Its immigration records, however, show no departure stamp, meaning there is no official record of them leaving the country.

The ministry flatly denied that Cambodian authorities helped arrest or transfer the two men. In its words, “the competent authorities of the Kingdom of Cambodia did not arrest and hand over the above individuals to Vietnamese authorities.”

Vietnam's Account

Information Cambodia received from Vietnam's Ministry of Public Security said the men were detained around 9:50 p.m. on September 18 at the Mi Cay Tay border post in Tay Ninh province, along with another Vietnamese man. Vietnamese authorities charge the three with illegally crossing into Vietnam and say they are members of Viet Tan, which Hanoi classifies as a terrorist organization.

Rights Groups Raise Alarm

The statement came after international lawyers and human rights organizations voiced concern about the circumstances of the disappearances. Civil society groups and UN human rights experts said Vietnam has recently worked very closely with neighboring governments to target pro-democracy activists. They noted that all the groups in question are based in democratic countries, yet Vietnam's communist government consistently labels them terrorist organizations.

On October 5, a network of international lawyers issued a joint statement condemning what it called the “abduction and forced transfer” of Nguyen Duc Thuan and Tran Hiep to Vietnam. The lawyers said that if Cambodian authorities had no role, Vietnamese agents acted freely on Cambodian soil in violation of the country's sovereignty. If Cambodian authorities did help, they said, that would amount to complicity in transnational repression.

The lawyers called on the United Nations and its Human Rights Council to review the case. They also urged Cambodia to guarantee an independent and impartial investigation into allegations of human rights abuses, including enforced disappearance and forced cross-border transfers.

Phil Robertson, director of Asia Human Rights & Labour Advocates, said Vietnam's confirmation that the men are in its custody points to a wider pattern of transnational repression in the region. He added that Hanoi has not yet made detailed information about the case public.

The case has also raised questions among observers about how the two men left Cambodia for Vietnam, given that Cambodian immigration records show no departure.
