On Monday, December 22, 2025, Thai Foreign Minister Sihasak Phuangketkeow briefed the press after the ASEAN special foreign ministers’ meeting on the Thailand-Cambodia situation, held in Kuala Lumpur, Malaysia.

The two-hour meeting, which started around 12.00pm local time, concluded without an agreement on a ceasefire between Thailand and Cambodia.

Sihasak emphasised that for the Kuala Lumpur Peace Declaration to be followed, a ceasefire must first be implemented. Thailand insisted that Cambodia must accept three conditions:

• Cambodia must be the first to declare a ceasefire, as the aggressor.
• The ceasefire must be real and continuous.
• Cambodia must show sincerity in cooperating with Thailand, particularly in clearing landmines, a matter Thailand cannot accept until resolved jointly.

Sihasak told the press, expressing gratitude to the Malaysian government as the host and reaffirming Thailand’s support for discussions under the ASEAN framework, as this is an issue that should be addressed at the regional level, reflecting the principle of ASEAN centrality.

He explained that Thailand has always had good intentions towards Cambodia, providing support and assistance during the civil war, including opening the border to accommodate refugees, offering shelter, and supporting economic recovery. This reflects Thailand’s commitment to peaceful coexistence with its neighbour.

Since the onset of the conflict during the previous government, Thailand has consistently sought to resolve the issue through bilateral discussions. However, Cambodia has attempted to bring the matter to the international stage, particularly under the framework of the United Nations, instead of engaging in direct talks.

Additionally, a conversation tape from the discussions was released, which Thailand views as unhelpful in resolving the issue and potentially undermining trust between the two countries. This action is seen as a violation of ASEAN’s principle of non-interference in domestic affairs.
