The agreement reinforces the ceasefire agreement reached in July 2025 following negotiations between the two countries. It also formalizes the establishment of an ASEAN observer group tasked with monitoring compliance and preventing further clashes in the border area.

The deal represents a significant milestone in ASEAN’s regional diplomacy, underscoring the bloc’s commitment to conflict prevention, stability, and cooperation during Malaysia’s 2025 Chairmanship under the theme “Inclusivity and Sustainability.”

Earlier, on October 25, Malaysian Foreign Minister Mohamad Hasan said that the withdrawal of heavy weapons from the border area, along with the removal and destruction of explosives and landmines, is a key component of the ceasefire agreement between Thailand and Cambodia. According to him, this initiative was intended to maintain the ceasefire that took effect in July, following an agreement between the Cambodian and Thai PMs to end hostilities.

Minister Mohamad Hasan emphasized that ASEAN hopes the ceasefire will be maintained, and urged both countries to continue dialogue and work towards a peaceful settlement of the border demarcation issue.

Thailand and Cambodia have long disputed their 817-kilometer shared border, with tensions recently escalating into military skirmishes. On July 28, Malaysian PM Anwar Ibrahim chaired a crucial meeting in Malaysia’s administrative capital, Putrajaya, between Cambodian PM Hun Manet and Thailand’s acting PM Phumtham Wechayachai, which successfully helped ease tensions along the two countries’ shared frontier.

The ceasefire, widely regarded as a major ASEAN achievement, has prevented a broader military escalation and ensured the safety of thousands of civilians.
