Hun Sen Accuses Thai PM of Insulting Monarchy Amid Rising Tensions

PHNOM PENH: In a significant escalation of diplomatic tensions between Cambodia and Thailand, former Cambodian Prime Minister Hun Sen publicly accused Thailand's Prime Minister Paetongtarn Shinawatra of insulting the Thai monarchy. This confrontation follows a leaked phone conversation concerning a recent border dispute that resulted in the death of a Cambodian soldier.

On June 27, 2025, Hun Sen, who served as Cambodia's Prime Minister for over three decades, took to his official Facebook page to express his grievances, stating, "I just let Thailand know how the prime minister committed a dirty act to their nation." The remarks were made during a livestream event, where he highlighted specific comments made by Paetongtarn regarding Lieutenant General Boonsin Padklang, which he deemed disrespectful to the Thai king.

Hun Sen's accusations stem from a leaked recording of a private conversation between him and Paetongtarn. In this conversation, the Thai PM reportedly referred to her military commander as an "opponent," which Hun Sen interpreted as a direct insult to the monarchy. He explained, "An insult to a regional commander is an insult to the Thai king because it is only the king who issued a royal decree to appoint him." This incident underscores the sensitive nature of military and royal relationships in Thai politics, particularly given the country's strict lese-majeste laws that prohibit insults to the monarchy.

The political landscape in Thailand has already been destabilized by this incident, with Paetongtarn's government losing majority support after the leaked conversation. The Bhumjaithai party, a key coalition partner, departed, stating that the phone call had "damaged the sovereignty and well-being of the country and Thai Army." This political fallout has raised serious questions about her future as prime minister, especially as conservative senators have moved to petition the Constitutional Court for her removal, citing violations of national integrity.

In a bid to underscore his position, Hun Sen stated, "I revealed all the secrets now" and suggested that he felt betrayed by the Shinawatra family, to which he once had close ties. He characterized Paetongtarn's actions as disloyal, claiming she had previously confided in him about her Cabinet's internal issues and plans. "But I chose not to tell her about Cambodia’s internal affairs," he remarked, indicating a growing mistrust.

Experts view this confrontation as indicative of broader geopolitical tensions in Southeast Asia, particularly concerning national identity and sovereignty. Dr. Lisa Chan, a political scientist at the University of Cambodia, commented, "This incident highlights the fragility of diplomatic relations in the region, where historical grievances and current political dynamics intersect."

The implications of this dispute extend beyond mere political theater. Economically, both nations stand to suffer from strained relations, particularly given their intertwined trade and tourism sectors. Dr. Michael T. Wong, an economist at Asia Development Bank, noted that any disruption in diplomatic ties could lead to significant economic repercussions: "Tourism is a vital lifeline for both economies, and any negative sentiment could deter visitors and investors."

Looking ahead, the unfolding situation will likely test the resilience of both governments. As Hun Sen expressed hope for Thailand to find a "new prime minister who can solve problems with Cambodia, Laos, and Myanmar," the call for stability in the region remains crucial. The Thai Constitutional Court's impending decision regarding Paetongtarn's fate may further influence the diplomatic landscape.

In conclusion, the confrontation between Hun Sen and Paetongtarn illustrates the precarious balance of power and perception in Southeast Asian politics. As both leaders navigate domestic pressures and international scrutiny, their actions will undoubtedly shape the future of Cambodia-Thailand relations and regional stability.
