On that occasion, ASEAN Observers Team inspected the actual situation regarding the unilateral construction of a border fence by the Thai military near Border Pillars No. 52 to No. 54, where they witnessed damage to temporary markers caused by this unilateral action. Following a briefing on the technical details of the joint survey and temporary demarcation efforts previously conducted by the joint survey teams of both countries, the ASEAN Observer Team – Cambodia (AOT-KH) inspected the sites where Thai citizens have occupied upon Cambodian territory for agricultural activities between Border Pillars No. 52 to No. 59.

In this regard, Cambodia has urged the prompt convening of the JBC to resolve these issues.

It also reaffirmed the position of the Royal Government of Cambodia that any border-related issues should be addressed peacefully through dialogue, in accordance with international law, existing bilateral Treaties and Agreements, and the established mechanisms of the Cambodia–Thailand Joint Boundary Commission (JBC).
