Ceasefire Holds Amid Fragile Peace in Cambodia-Thailand Border Dispute

By Helga Mbodze, Reporter | (Daystar University), Nairobi – Kenya.

A ceasefire is now in effect on the Cambodia-Thailand border, following the deadliest flare-up in over a decade. The peace is fragile, as deep-seated issues remain unresolved.

These include undemarcated borders, conflicting national narratives, and a profound lack of trust between the two countries.

The Cyclical Nature of a Decades-Long Conflict

The recent hostilities are not a new event. They are the latest chapter in a long-running conflict rooted in historical ambiguities. The dispute’s origins trace back to the Franco-Siamese treaties of 1904 and 1907.

These colonial-era agreements left large parts of the 800-kilometer border undefined. For over half a century, this has been a source of constant friction.

A major point of contention has always been the ancient Hindu temple of Preah Vihear. The International Court of Justice (ICJ) first ruled the temple to be in Cambodian territory in 1962.

The dispute flared up again in 2008 and again in 2013, with a new ICJ ruling. The court reaffirmed Cambodia’s sovereignty over the temple’s promontory but left other areas for bilateral negotiation.

This ensured the „scope for discord“ would continue, proving that the core issues are never truly resolved, but merely lie dormant.

A Detailed Timeline of a Fragile Peace

The recent conflict unfolded in a predictable way. Tensions began in February 2025 when Thai soldiers stopped Cambodian tourists at a disputed temple.

The first deadly skirmish took place in May, with a Cambodian soldier dying. Both sides blamed the other, a pattern that defined the conflict.

Bilateral talks failed to de-escalate the situation. Instead, Thailand reinforced its military presence. Cambodia responded by banning Thai imports and appealing to the ICJ.

The situation worsened in July with landmine incidents that injured Thai soldiers. Thailand claimed the mines were new, while Cambodia denied responsibility.

These incidents led to a major military confrontation on July 24. The battles were the deadliest in over a decade. It was only through significant international pressure, especially from the United States, that a ceasefire was brokered on July 28.

President Donald Trump’s administration had used economic leverage by threatening to withhold trade pacts to bring both sides to the table.

Humanitarian Crisis and Conflicting Narratives

The human cost of this conflict has been substantial. Five days of fighting resulted in the deaths of 35 to 41 soldiers and civilians. Between 260,000 and 300,000 people were displaced from their homes.

For the people in the border regions, the issues are about security and survival. Relief groups have warned of the lingering wounds of war, including hidden landmines and destroyed homes.

The narratives from Phnom Penh and Bangkok have been completely different. Cambodia has consistently alleged that Thailand initiated the hostilities with „unprovoked“ attacks and used banned weapons.

Thailand, in turn, maintains that Cambodian soldiers fired first. It denies the use of toxic smoke, calling the claims „fake news.“ This mutual blame game makes finding the facts difficult.

International vs. Bilateral Diplomacy

A fundamental difference remains in how the two nations want to resolve the dispute. Cambodia prefers international adjudication through the ICJ. This position has strong public support.

In contrast, Thailand rejects the ICJ’s jurisdiction. It prefers a bilateral approach using existing mechanisms like the Joint Boundary Commission (JBC). This deep ideological divide is the greatest obstacle to a lasting peace.

While leaders have met for talks, these have focused on avoiding new clashes, not on core territorial claims. The recent royal decree from Cambodian King Norodom Sihamoni signals a unified defense stance.

Meanwhile, Thailand’s domestic politics are turbulent, with the suspension of its Prime Minister.

A Fragile Peace on the Brink

The ceasefire holds for now, but it is a fragile peace built on mutual suspicion. The core question of where the border lies remains unanswered.

Until both nations can find a way to a trusted and lasting solution, this truce will remain just that: a fragile peace, waiting for the next spark.

The international community has shown it can de-escalate a conflict, but the long-term responsibility for peace rests squarely with Cambodia and Thailand.

For the people on the border, the hope is that this peace will be more than just a momentary silence between battles.
