Resolving Cambodia-Thailand Maritime Dispute: UNCLOS Conciliation Process Initiated
Cambodia and Thailand have initiated a United Nations-backed dispute resolution process to address overlapping maritime claims in the Gulf of Thailand, where valuable undersea energy reserves are estimated at around US$300 billion. The two Southeast Asian nations have a history of territorial disputes dating back to the French colonial era, with ongoing disagreements over maritime territories and the demarcation of their 800-km land border.
Thai Prime Minister Anutin Charnvirakul expressed surprise at Cambodia's move to start a compulsory conciliation process under international law to resolve the maritime boundary dispute. Despite a ceasefire agreement reached in December following border clashes, both countries have accused each other of violating the truce. Cambodia's decision to initiate the mediation process under the United Nations Convention on the Law of the Sea (UNCLOS) came after Thailand canceled a 2001 bilateral agreement on overlapping maritime claims and energy exploration.
Cambodian Prime Minister Hun Manet announced on state television that his government had formally notified Thailand and the United Nations secretary-general to begin compulsory conciliation proceedings under UNCLOS. Hun Manet emphasized the importance of protecting Cambodia's sovereignty and maritime rights in accordance with international law. Both countries, as parties to the UN convention, have the opportunity to reach a fair and lasting settlement with the guidance of international expert conciliators.
Thailand's foreign ministry did not immediately respond to requests for comment on the matter. The energy ministry in Thailand has estimated potential revenues from oil and natural gas in the disputed area to be worth approximately US$300 billion. The long-standing border dispute between Cambodia and Thailand escalated into armed conflict in July and December, resulting in casualties and control of border provinces claimed by both nations. Cambodia has called for the withdrawal of Thai forces from disputed areas and criticized Thailand for damage to heritage temples during the clashes.
In conclusion, Cambodia and Thailand have taken steps to address their maritime boundary dispute through a United Nations-backed dispute resolution process. The initiation of compulsory conciliation proceedings under UNCLOS aims to protect each country's sovereignty and maritime rights while seeking a fair and lasting settlement with the guidance of international experts. The dispute over overlapping maritime claims in the Gulf of Thailand underscores the complex history of territorial disagreements between the two Southeast Asian nations.
