Pro-democracy group Viet Tan says Vietnam abducted two of its members, an Australian and a Norwegian citizen, in Cambodia and forced them across the border; Hanoi confirms it arrested Tran Hiep and Nguyen Duc Thuan but says they entered with forged papers to carry out terrorism, and has charged them with membership of a terrorist organisation. Viet Tan, which Vietnam labels a terrorist group, calls the claim a fabrication and describes the case as transnational repression that violates Cambodian sovereignty, while Australia says it is giving consular support to Tran's family. The case matters because rights groups say it fits a wider pattern of Vietnam pursuing dissidents abroad in Southeast Asia.
