Thai and Cambodian prime ministers have pledged to cooperate more closely in order to prevent political interference across their borders. The commitment came during Cambodian Prime Minister Hun Manet’s visit to Bangkok, where he thanked Thai Prime Minister Srettha Thavisin for preventing the actions of exiled Cambodian activists in Thailand. Last week, Thai immigration police arrested three activists and their families ahead of a planned protest against Hun Manet’s visit. The activists had recently sought asylum in Thailand and had been granted refugee status. Human rights groups have called for their release.
