"An Untrustworthy State": Thailand's Unilateral Termination of the 2001 MOU and Its Evasion of International Legal Settlement
Thailand's decision to unilaterally terminate the 2001 Memorandum of Understanding (MOU 2001) has generated significant controversy. The agreement was jointly signed by both Cambodia and Thailand to establish a Bilateral Negotiation Framework for addressing maritime boundary issues and the Overlapping Claims Area (OCA).
For more than 25 years, Cambodia has continued to participate patiently in bilateral negotiations while honoring the existing agreements. However, repeated rounds of negotiations failed to produce meaningful progress, as delay tactics and indefinite postponements repeatedly stalled the process.
Thailand later unilaterally revoked the 2001 MOU and has also been reported to be seeking the cancellation of the 2000 MOU. Such actions have been viewed as abandoning the very negotiation framework that both countries had previously agreed upon. Nevertheless, Thailand has accused Cambodia of closing the door to bilateral negotiations by opting for an international legal settlement.
From Cambodia's perspective, however, seeking a resolution through international law does not constitute a rejection of bilateral dialogue. Rather, it represents the use of internationally recognized legal mechanisms when negotiations have failed to produce a solution. In particular, the United Nations Convention on the Law of the Sea (UNCLOS) provides mechanisms for the peaceful settlement of disputes.
According to Cambodia's position, its decision to pursue dispute settlement under UNCLOS came only after more than two decades of bilateral negotiations had failed to achieve substantial progress, and after Thailand unilaterally terminated the 2001 MOU.
Some analysts argue that repeatedly avoiding international dispute settlement mechanisms, or refusing to accept adjudication by international legal institutions, raises legitimate questions about a state's commitment to the international rule of law and the principle of good faith in the implementation of international agreements.
From this perspective, the characterization of "Thailand as an untrustworthy state" represents a political assessment expressed by some members of the international community, particularly by countries that consider themselves adversely affected when another state fails to comply with international law.
