Cambodia's Prime Minister Hun Manet met United Nations Secretary-General António Guterres in Beijing on September 1, with talks focusing on Cambodia’s active role within the UN system and the ongoing border dispute with Thailand.

According to Khmer Times, Hun Manet reported that the UN chief praised Cambodia’s constructive engagement as a member state, highlighting its contributions to various areas of international cooperation.

On the border situation, Guterres assured the Cambodian leader that he has been closely monitoring developments. He welcomed the recent ceasefire between Cambodian and Thai forces, describing it as an important step towards de-escalation, and urged both sides to work towards restoring normal bilateral relations as quickly as possible.

Quoting the Secretary-General, Hun Manet said: “He has personally and attentively followed the issue, welcomed the ceasefire, and encouraged both sides to normalise relations soon.”

The UN leader also endorsed Cambodia’s proposal that both nations refrain from using military means to address unresolved border disputes, particularly in areas populated by civilians. Instead, he underlined the importance of resolving differences peacefully, making use of established bilateral mechanisms such as the Cambodia–Thailand Joint Boundary Commission (JBC).

According to Hun Manet, “The Secretary-General has agreed to call on both parties to avoid military action in unsettled border areas, especially those with civilian populations, and to resolve disputes through mechanisms like the JBC, guided by agreements, treaties, and international law.”

The meeting took place during Hun Manet’s official visit to China, where he is participating in a series of events and high-level discussions with global leaders.
