What is the estimated value and composition of Cambodia's disputed undersea energy resources in the Gulf of Thailand?

The disputed maritime area of around 27,000 square km in the Gulf of Thailand—claimed by both Cambodia and Thailand—is estimated to hold approximately 11 trillion cubic feet of natural gas alongside large quantities of oil, with the total resource value assessed at $300 billion.

Why has Cambodia decided to pursue the UNCLOS Compulsory Conciliation process with Thailand, and what triggered this decision?

Cambodia will now rely on the UNCLOS Compulsory Conciliation process because Thailand unilaterally terminated their 25-year-old joint offshore energy exploration agreement this month, citing lack of progress; Cambodian Energy Minister Keo Rottanak stated this conciliation mechanism is 'the only possible avenue to sort out differences in a peaceful and amicable manner.'
