(Phnom Penh): After enduring one of the most tense and painful periods in the history of Cambodia–Thailand relations, marked by two major armed confrontations and repeated violations of ceasefire agreements, the renewed face-to-face meeting between Cambodian Prime Minister Hun Manet and Thai Prime Minister Anutin Charnvirakul in Cebu, Philippines, on May 7, 2026, may be viewed as an important political step toward easing tensions and seeking a more durable peace.

The meeting was not merely a routine diplomatic encounter between two leaders. It represented the reopening of “post-war diplomacy” following the 2025 border conflict, which left casualties, widespread destruction, and hundreds of thousands of displaced civilians on both sides of the border.

After War and Repeated Ceasefire Violations: Why the Cebu Meeting Matters

During the trilateral meeting facilitated by Philippine President Ferdinand Marcos Jr. in his capacity as ASEAN Chair, the leaders of Cambodia and Thailand demonstrated signs of renewed engagement through a shared commitment to peace and the normalization of bilateral relations.

What stood out most was the position of the Cambodian government, which continued to demonstrate restraint and commitment to resolving disputes peacefully despite Cambodia having suffered military attacks, temporary territorial losses, infrastructure destruction, and severe humanitarian consequences.

Prime Minister Hun Manet stated:

“Today, Prime Minister Anutin and I met with a shared commitment to lasting peace. Our discussions focused on tensions and confidence-building measures aimed at restoring and strengthening frameworks for long-term peace and normalizing relations.”

The remarks reflected Cambodia’s consistent policy of prioritizing “law and diplomacy” as the key pathway for resolving the crisis.

This approach was clearly demonstrated through Cambodia’s continued support for bilateral mechanisms such as:
- JBC (Joint Boundary Commission)
- GBC (General Border Committee)
- RBC (Regional Border Committee)

as well as Cambodia’s decision to initiate “Compulsory Conciliation” under the United Nations Convention on the Law of the Sea (UNCLOS), after Thailand unilaterally withdrew from the 2001 Memorandum of Understanding (MoU 2001).

Cambodia Chooses Law and Diplomacy Over Military Confrontation

In the same speech, Prime Minister Hun Manet delivered one of Cambodia’s clearest messages regarding the principle that borders cannot be altered through force or through a “fait accompli” — a legal term referring to the creation of new realities on the ground through force and then compelling others to accept them afterward.

Hun Manet stated:

“We believe this mechanism will be essential to ending the practice of ‘fait accompli’ on the ground and ensuring that sovereignty, territorial integrity, and international borders are respected in accordance with international law, treaties, and existing agreements, thereby promoting confidence and bringing lasting peace between our two countries.”

This statement was not merely about defending Cambodia’s sovereignty. It also underscored Cambodia’s determination to ensure that future dispute resolution remains grounded in international law rather than the “law of the strongest.”

At the same time, Cambodia highly valued the role of the ASEAN Observer Team (AOT) and called on ASEAN to continue playing a role in verifying and ensuring compliance with ceasefire agreements. This demonstrated that Cambodia does not want peace to depend solely on political promises, but rather on credible and verifiable mechanisms capable of safeguarding stability.

From Nationalism to Diplomacy: Thailand’s Changing Political Language

On the Thai side, the position of Prime Minister Anutin also reflected signs of de-escalation. He emphasized that conflict “brings only loss and suffering” and called on both countries to “walk this path together toward peace.”

Although Anutin returned to power through a nationalist political platform, his speech in Cebu suggested that Thailand’s new government is beginning to recognize that prolonged confrontation cannot serve the long-term interests of either country.

This shift in political language is particularly significant because, during Thailand’s 2026 election campaign, the Cambodia–Thailand border issue was heavily used in domestic politics. Several nationalist groups employed strong rhetoric centered on sovereignty, territorial claims, and emotionally charged nationalism to rally public support. During that period, border tensions evolved from a security issue into a domestic political tool.

However, after officially assuming office, Thailand’s new government now faces a different reality — one in which nationalist rhetoric can no longer be used in the same way on the international diplomatic stage. Prolonged conflict and tensions fueled by nationalism not only create security risks, but also threaten economic stability, trade, tourism, regional relations, and Thailand’s international credibility.

For a country that relies heavily on an open economy, foreign investment, and tourism, prolonged instability and conflict with neighboring countries could significantly undermine investor confidence and economic conditions. Moreover, continued confrontational rhetoric risks international criticism and could weaken Thailand’s image as a supporter of regional stability.

At a time when Association of Southeast Asian Nations (ASEAN) and major powers are pushing for peaceful solutions, continuing to use election-style confrontational rhetoric could place Thailand under greater diplomatic pressure and make the crisis even harder to manage. In this sense, the statements made by Thailand’s new leadership in Cebu may be interpreted as the beginning of a shift from “nationalist politics” toward “crisis-management diplomacy.”

From Battlefield to Negotiating Table: Can Cambodia and Thailand Open a New Chapter?

For Cambodia, the Cebu meeting demonstrated that despite enduring war, loss, and repeated violations of agreements, the country remains open to dialogue and reconciliation. This reflects the Cambodian government’s long-standing argument that defending national sovereignty and pursuing peace are not contradictory goals, but can coexist if solutions are based on international law and credible mechanisms.

During the meeting, the Cambodian and Thai prime ministers tasked their foreign ministers with continuing detailed discussions to move implementation forward in a practical and results-oriented manner, as expected by the ASEAN Chair. This indicated that the Cebu meeting was not merely symbolic diplomacy or a photo opportunity, but rather the beginning of a new negotiation process aimed at transforming political statements into practical implementation.

Prime Minister Hun Manet concluded:

“Cambodia believes this is a peaceful pathway toward a fair solution for both sides. Cambodia remains firmly committed to resolving disputes peacefully based on international law and existing agreements, including the commitments reaffirmed in the Kuala Lumpur Joint Declaration of October 26, 2025, and the Joint Statement of December 27, 2025. Cambodia stands ready to move forward constructively, swiftly, and in good faith.”

The message carried significance beyond a simple call for peace. It reaffirmed Cambodia’s desire for a “rule-based peace,” grounded in international law rather than military power. Cambodia is attempting to anchor future negotiations within international legal frameworks, existing agreements, and ASEAN mechanisms to ensure that peace does not become merely a temporary pause in conflict.

Conclusion

Nevertheless, the road to peace remains fragile. The erosion of trust, past ceasefire violations, and lingering questions about future compliance continue to pose major challenges. Therefore, the Cebu meeting should not be seen as the end of the crisis, but rather as the possible beginning of a “post-war phase” requiring patience, diplomacy, and careful rebuilding of confidence between both sides.

In this sense, the Cebu meeting represents an attempt to transform the conflict:
- from the battlefield to the negotiating table,
- from the use of force to the use of law,
- and from confrontation to a peace-building process supported by credible mechanisms.

If this process can move forward in good faith and with respect for international law, it may eventually become a new chapter in Cambodia–Thailand relations after one of the most painful crises in recent decades.
