Bangkok: The Ministry of Foreign Affairs has clarified its acceptance of the UNCLOS compromise agreement to clear maritime boundaries, expressing a hope for a conclusion within one year. The Ministry emphasized that the UNCLOS mediation process is not a court case, and there is no winner or loser, ensuring no political interference throughout.
According to Thai News Agency, the Ministry of Foreign Affairs held a press conference to discuss Thailand's decision to participate in the conciliation process for maritime boundary disputes under the 1982 United Nations Convention on the Law of the Sea (UNCLOS). The briefing was led by Ms. Maratee Nalita Andamo, Acting Director-General of the Department of Information and Deputy Spokesperson, and Mr. Benjamin Sukanjanathee, Director-General of the Department of Treaties and Legal Affairs.
Ms. Maratee disclosed that on June 19, 2026, Thailand informed Cambodia of its acceptance of the UNCLOS process. The letter to Cambodia highlighted three key points: the aim to define maritime boundaries, the appointment of Thai representatives in the process, and the naming of two mediators selected by Thailand, Albert J. Hoffmann and Rdiger Wolfrum, both renowned experts in maritime law.
The process requires both Thai and Cambodian mediators to appoint a fifth mediator to chair the compromise committee within 30 days of the letter. This process is expected to last about 12 months, or possibly longer, to prepare a report, engage in discussions, and gather perspectives from both countries. The recommendations are non-binding but serve as guidelines for bilateral negotiations, a method initially proposed by Thailand.
Mr. Benjamin Sukanjanathee explained that the mandatory compromise process is a bilateral effort with third-party participation. Discussions should be completed within a year if the border demarcation process is finalized. Once the first step is complete, the issue will be presented to the Cabinet and Parliament for signing. If parts of the agreement are incomplete, it remains a matter of sovereignty requiring Cabinet and Parliamentary approval.
Emphasizing the non-political nature of the mediation, Mr. Benjamint stressed the importance of both countries acting in good faith. He noted that mediators have the right to intervene if there is manipulation of news or international public opinion. Thailand has confidence in the mediation process, opting for mandatory mediation over court proceedings.
Mr. Benjamint also addressed the potential impact of a land border dispute arising during the reconciliation process, clarifying that it is a separate international process. He expressed optimism that success in this maritime boundary process could enhance other aspects of bilateral relations.
The Ministry maintains that historical evidence and thorough preparation, including international consultations and technical requirements, bolster Thailand's position in the compromise process. The process is seen as vital for achieving a clear demarcation line, which would be beneficial for both countries.
