Prime Minister Hun Sen departed on Friday for the 32nd Asean Summit in Singapore, leading a Cambodian delegation that included Foreign Minister Prak Sokhonn, Commerce Minister Pan Sorasak and Education Minister Hang Chuon Naron.
The two-day meeting, under the theme "Resilient and Innovative ASEAN", kicks off amid calls from human rights groups for member states to intervene in Cambodia's "severe deterioration in the state of human rights and democracy."
Human Rights Watch and Asean Parliamentarians for Human Rights were among the groups that released a letter Wednesday calling for Cambodia's government to restore a fair environment for the national election.
According to a statement from the Ministry of Foreign Affairs, leaders will discuss cybersecurity cooperation, Asean's external relations and its "future directions."
Hun Sen will also hold bilateral meetings with some Asean leaders on the sidelines of the summit, according to the ministry.
Singaporean Prime Minister Lee Hsien Loong is chairing the summit.
