The Deafening Silence on the Thai-Cambodian Border

Sitting, as a ‘farang’, on a plane from Bangkok to London, I can’t help but wonder about the reignited conflict between Cambodia and Thailand. Here are some thoughts.

You might be forgiven for missing it. Amid the grand theatre of global power struggles and the unending dramas of the Middle East, the sudden eruption of heavy artillery fire between Thailand and Cambodia feels like a dispatch from another era. A forgotten conflict, a throwback to a time when nations hurled shells at one another over scraps of contested jungle and the precise location of crumbling colonial-era border stones. And yet, here we are in 2025, with two supposedly modernising Southeast Asian neighbours engaged in what can only be described as a fit of organised, state-sanctioned madness.

Let’s be absolutely clear on the facts, because they are as grim as they are baffling. For two days, heavy fire has been exchanged across the border. Ceasefire calls, issued with all the urgency of a weather report, have failed. And most importantly, over 130,000 people — not soldiers, not strategists, but ordinary farmers and families — have been forced to flee their homes. I wonder, though, whether, in our rush to analyse the geopolitical chessboard, are we once again in danger of forgetting the human beings swept off the board entirely?

This piece is not about litigating the historical claims to this patch of land; frankly, that is a task for dusty archives and international lawyers, not artillery battalions. This is about asking a far more urgent question: in an era of unprecedented regional connectivity and economic ambition, why are we countenancing this pinnacle of political folly? And where, in all this, is the voice of regional reason?

A Fever Dream of Maps and Martyrs

To understand this conflict, one must first understand the potent, and often toxic, brew of nationalism that political leaders in both Bangkok and Phnom Penh find so irresistible. This isn’t a war over resources, not really. It is a war of maps and ghosts; a conflict fuelled by historical grievances and the ever-present need for politicians to wrap themselves in the flag.

And let’s be honest, this is not a fire that started yesterday. The kindling has been laid for centuries. Anyone with a passing knowledge of the region knows that the relationship between the Thai and Khmer peoples is layered with the ghosts of long-dead empires. The shadow of Angkor, the historical narratives of dominance and subjugation, the bitter and emotional dispute over the Preah Vihear temple which went to the world court decades ago — these are not just footnotes; they are the open wounds that nationalist demagogues love to poke with a sharp stick. It isn’t just about a border; it’s about a deep-seated, often irrational, sense of historical identity and rivalry that can be weaponised in an instant.

Is it any coincidence that this erupts now? In Thailand, one can’t help but notice the permanent political class in the barracks, an establishment that always benefits from a national security crisis to justify its budget and its enduring influence over civilian affairs. In Cambodia, with a historic leadership transition solidifying its power, what better way to forge national unity and command respect than a muscular defence of sovereign territory? For the leaders in both capitals, this conflict is a tragically convenient sideshow, a perfect distraction from tricky domestic questions about economic reform, political freedom, and the distribution of power. It’s the oldest play in the book, and our people are paying the price for their lack of imagination.

Are we truly to believe that the best way to secure national prosperity in the 21st century is to send young men to kill each other over disputed temple ruins and ill-defined watersheds? Or is it perhaps more likely that this flare-up serves another, more cynical purpose? For leaders facing domestic pressures, nothing distracts quite like an external enemy. A border skirmish is a perfect tool to galvanise support, silence critics, and reassert a ‘strongman’ image. It is a dangerous and deeply irresponsible game, played with the lives of soldiers and the livelihoods of the 130,000 displaced souls who are now the primary victims of this manufactured crisis.

One cannot help but feel that both nations are caught in a fever dream of their own making, sacrificing the tangible benefits of peaceful cooperation for the abstract, chest-thumping satisfaction of patriotic fervour. It is a monumental failure of statesmanship on both sides of the border.

ASEAN’s Sound and Fury, Signifying Nothing

And where, you might ask, is the vaunted regional bloc, the Association of Southeast Asian Nations (ASEAN), in all of this? The organisation, founded on the very principle of preventing such conflicts, appears to be paralysed, hiding behind its most sacred — and most debilitating — doctrine: non-interference.

This principle, once a noble defence against colonial meddling, has decayed into a convenient fiction, a gentleman’s agreement amongst leaders to look the other way so long as the trouble remains manageable. We see statements of ‘deep concern’ and calls for ‘dialogue’, of course. We always do. But what we don’t see is decisive action. We don’t see the convening of an emergency summit with teeth. We don’t see the threat of diplomatic or economic consequences.

But are we to ignore the larger shadows looming behind this regional stage? When two smaller nations fight, any rational observer must ask: Cui bono? Who benefits? One cannot help but notice Beijing’s sphinx-like silence on the matter, offering platitudes while its economic and military influence over both nations, particularly Cambodia, grows ever deeper. Is this chaos a test of ASEAN’s already questionable relevance, further paving the way for Chinese dominance? And where is Washington? Is it too distracted by its other global entanglements to pay attention, or does it see an opportunity to pull a rattled Thailand closer into its security orbit? This local border war is in danger of becoming yet another square on the great geopolitical chessboard, a proxy battleground where Southeast Asian lives are, once again, the cheapest currency.

What is the purpose of a regional stability pact if it falls silent the moment two of its members start a shooting war? ASEAN’s response thus far is a case study in institutional impotence. Its silence is not golden; it is the sound of complicity, the tacit admission that its diplomatic machinery is no match for the nationalist impulses of its own members.

Beyond Flags and Fury: A Diplomatic Way Forward

To simply critique, however, is not enough. To point out the madness without offering a path back to sanity is an empty exercise. The solutions to this are not complex; they do not require geopolitical genius. They require only a dose of common sense and the political will to choose prosperity over posturing.

First, the immediate and obvious step: De-escalation through a Demilitarised Zone. Both sides must agree to an immediate, monitored withdrawal of all military personnel and heavy weapons from a clearly defined corridor along the disputed border. This isn’t a concession; it is the prerequisite for any adult conversation. Let neutral observers, perhaps from other ASEAN states or the UN, move in to monitor the buffer zone and build a modicum of trust.

Second, resolve the issue itself through Binding International Arbitration. The dispute is fundamentally a legal one about the interpretation of old treaties and maps. Let it be settled by legal experts, not by competing artillery barrages. Both Thailand and Cambodia should publicly commit to taking their case to the International Court of Justice and — this is the crucial part — to unconditionally accept its final ruling as the definitive border. This takes the explosive issue out of the hands of nationalist politicians and places it in the hands of impartial international law.

Finally, and most constructively, shift the entire paradigm with Joint Economic Development. Instead of a line on a map to be fought over, why not transform the entire contested region into a ‘Trans-Boundary Zone of Peace and Prosperity’? Imagine a jointly administered national park to protect the area’s heritage, joint ventures in eco-tourism, and special economic zones that benefit communities on both sides. By creating shared economic interests that are more valuable than the land itself, you make the conflict not only unnecessary but economically illiterate.

This is the choice facing Bangkok and Phnom Penh. They can continue down this path of nationalist folly, sacrificing their own people on the altar of historical grievances. Or they can choose a pragmatic path that replaces conflict with cooperation and transforms a zone of contention into a source of shared wealth. The latter seems like common sense, doesn’t it? One can only hope it’s not too late for common sense to prevail.
