Cambodia and Thailand Advance Maritime Dispute via UNCLOS

Phnom Penh and Bangkok have committed to six additional sessions of mandatory conciliation to resolve their maritime boundary conflict.
Cambodia and Thailand have agreed to continue their maritime boundary dispute through six further sessions of mandatory conciliation under the United Nations Convention on the Law of the Sea. According to reports from GN geopolitics/border, this procedural step follows the conclusion of the first meeting in Singapore on September 16, where both parties confirmed their intent to engage with the issues presented by the tribunal.
The initiative was launched by Cambodia to establish a new framework for resolution after Thailand canceled the 2001 Memorandum of Understanding in May. Foreign Minister Prak Sokhonn stated that this move ensures both nations have a peaceful and legal mechanism to address their overlapping claims in the Gulf of Thailand, replacing the previously agreed-upon diplomatic channels.
Scheduled Timeline for Hague Sessions
The second round of negotiations is set to take place between October 14 and 18 in The Hague, Netherlands. Minister Sokhonn indicated that this session is expected to last approximately four and a half days, providing a dedicated window for detailed legal and technical discussions. Subsequent meetings are planned for November, late January or February, April, May, and July, though specific dates and locations remain to be finalized.
Officials noted that the April session coincides with the Khmer New Year, a period traditionally marked by diplomatic activity in the region. Both delegations are currently preparing documentation and evidence to support their positions, aiming to submit a comprehensive report with recommendations for future negotiations. The process is designed to allow for a gradual build-up of consensus over several months.
Strategic Options for Boundary Resolution
Cambodia has outlined three distinct pathways it seeks to achieve through this conciliation process. The primary objective is to secure a treaty establishing a comprehensive maritime boundary in accordance with international law. If a definitive boundary line cannot be agreed upon, the second option involves an agreement to jointly develop seabed resources and equitably share the resulting benefits.
Should both of these primary options fail, the third pathway entails proposing alternative measures to manage the dispute. Minister Sokhonn emphasized that the goal is a fair and sustainable resolution guided by international experts. The ministry expressed confidence that international law offers a viable pathway for peaceful resolution, highlighting a commitment to constructive participation and mutual benefit in energy resource development.
Diplomatic Context and Regional Implications
This diplomatic effort comes at a time of heightened regional sensitivity, with recent appointments such as the new US Ambassador to Cambodia focusing on combating online scams. The maritime dispute remains a central pillar of bilateral relations, and the shift to UNCLOS conciliation signals a desire to depoliticize the issue through legal frameworks. Observers note that maintaining a structured dialogue is crucial for stability in the Gulf of Thailand.
As the parties move toward The Hague, attention will turn to the specific legal arguments presented by each side. The outcome of these sessions will likely influence broader regional dynamics regarding maritime sovereignty and resource management. For now, the focus remains on the procedural steps required to bring the dispute to a durable and legally sound conclusion.
