Vietnamese authorities have detained three human rights activists — including Tran Hiep, a Vietnamese-Australian democracy campaigner, and Nguyen Duc Thuan, a Vietnamese-Norwegian activist — who allegedly disappeared in Cambodia before surfacing in Vietnamese custody. Hanoi claims the men were arrested illegally crossing into Vietnam and will face terrorism and document-forgery charges, but the pro-democracy group Viet Tan (a Vietnamese diaspora political party banned in Vietnam but operating lawfully in many Western countries) says the pair were abducted during a human rights training visit and had no intention of entering Vietnam. Australian Prime Minister Anthony Albanese confirmed consular assistance is being provided, while rights groups condemned the incident as an act of transnational repression, noting that Vietnam has arrested more than 55 activists under broad criminal laws in 2025 alone.
