Leaked Phone Call Triggers Domestic Uproar
The Thailand-Cambodia dispute has erupted into a full-blown political and military crisis after a leaked phone call between Thai Prime Minister Paetongtarn Shinawatra and former Cambodian Prime Minister Hun Sen surfaced online. The leaked conversation, which occurred on June 15, 2025, has triggered domestic uproar in Thailand and worsened civil-military tensions. At the core of the Thailand-Cambodia dispute is a border clash that took place on May 28, which has reignited historical grievances between the two Southeast Asian nations.
Military Reference and Diplomatic Tone Spark Reactions
In the leaked audio, PM Paetongtarn referred to the Second Army Region commander, Lieutenant General Boonsin Padklang, as “an opponent.” The informal and seemingly dismissive tone used to describe a senior military officer shocked many. During the call, she also referred to Hun Sen as “uncle,” which has added a diplomatic twist to the Thailand-Cambodia dispute.
Emerald Triangle Border Clash Reignites Tensions
The conversation revolved around the fatal border incident in the Emerald Triangle—a politically sensitive region where Thailand, Cambodia, and Laos meet. According to Lt. Gen. Boonsin, Cambodian troops entered 150 meters inside Thai territory and started digging defensive trenches. Thai soldiers responded, and cross-border gunfire was reported. A Cambodian soldier was killed in the skirmish. The Thailand-Cambodia dispute flared up once again over this conflict zone, which has long been a hotspot of tension.
PM Paetongtarn’s Apology and Damage Control Efforts
Attempting to calm the growing storm, PM Paetongtarn traveled to the northeastern Thai region of Chong Bok, where Boonsin is stationed. She phoned him to offer an apology and scheduled a face-to-face meeting to address the misunderstanding. However, the damage was already done, and the Thailand-Cambodia dispute began to spiral into broader political chaos.
Army’s Subtle Criticism of the PM
Boonsin later told the media that he advised the Prime Minister to put national interests and moral integrity above politics in sensitive matters like border security. His comments, though diplomatic, implied disapproval of how the Prime Minister handled the Thailand-Cambodia dispute.
Coalition Government in Danger
The political fallout was swift. On June 19, the Bhumjaithai Party, a conservative coalition partner, announced that it would withdraw support from the ruling government. The party accused the Prime Minister of undermining the military’s authority and compromising Thailand’s sovereignty. This has left the ruling Pheu Thai Party-led coalition with a fragile hold on power in the 500-member Thai parliament.
Diplomatic Fallout and ICJ Complaint
As the Thailand-Cambodia dispute escalated, the Thai government officially protested the leak, calling it a breach of diplomatic norms. They demanded an explanation from Cambodia and accused it of damaging bilateral trust. Cambodia’s current Prime Minister Hun Manet—Hun Sen’s son—responded by revealing that his government had already filed a formal complaint with the International Court of Justice (ICJ).
Historical Roots of the Thailand-Cambodia Dispute
The Thailand-Cambodia dispute is deeply rooted in history. The two countries have long been at odds over border demarcations. The most prominent case involved the Preah Vihear Temple. In 1962, the ICJ ruled in favor of Cambodia, declaring the temple as Cambodian territory. Though Thailand accepted the verdict, disputes over surrounding land have persisted. The recent conflict is a continuation of these age-old tensions.
Trade and Cultural Impact of the Dispute
The diplomatic rift has already impacted trade and culture. Cambodia has halted the import of Thai fruits and vegetables. In retaliation, Thailand has tightened border crossings for Cambodian nationals. Cambodian media has also imposed a temporary ban on broadcasting Thai drama shows, highlighting how far-reaching the Thailand-Cambodia dispute has become.
Failed De-escalation and Rising Internal Pressure
Efforts to de-escalate the situation were made on June 12, when both countries agreed to ease tensions through diplomatic dialogue. But the leak of the phone conversation on June 19 has reversed much of that progress. The Thailand-Cambodia dispute is once again straining not only international relations but also internal governance in Thailand.
A Test of Leadership for PM Paetongtarn
The Prime Minister now faces enormous pressure. Not only must she restore confidence in her leadership, but she also has to repair the country’s fragile alliance with its military and prevent further diplomatic fallout. The Thailand-Cambodia dispute has become a litmus test for her administration’s ability to navigate complex international and domestic challenges simultaneously.
Uncertain Political Future Amid Ongoing Dispute
It remains to be seen whether PM Paetongtarn can recover from the damage caused by a single phone call. As political alliances shift and public trust wavers, the future of her government hangs in the balance. The Thailand-Cambodia dispute continues to evolve, with potential ramifications for Southeast Asian diplomacy, regional security, and the democratic future of Thailand itself.
