History

Historical Context

After the United Nations Convention on the Law of the Sea entered into force on 16 November 1994, establishing 200-nautical-mile exclusive economic zones for 169 sovereign states, maritime boundaries shifted from the historic three-mile rule. In May 2026 Thailand’s prime minister ended the 2001 Thailand-Cambodia MOU, prompting Cambodia’s deputy prime minister to invoke UNCLOS conciliation, echoing the treaty’s dispute-resolution legacy.
