Bangkok: Thailand and Cambodia's ceasefire, once celebrated as a diplomatic success, has swiftly disintegrated, leading to the most severe border escalation since July. The renewed hostilities have resulted in at least 15 deaths and displaced over half a million civilians from both nations.
According to Anadolu Agency, the two neighboring countries have accused each other of rekindling the conflict, which appeared to have been resolved with a peace deal brokered by U.S. President Donald Trump in Malaysia last October. This agreement came after deadly clashes in July that resulted in 48 fatalities before Trump intervened to halt the violence temporarily.
The resumption of hostilities, accompanied by heated rhetoric from both sides, was deemed almost inevitable by analysts, who caution that the clashes could escalate into a larger crisis. Pavin Chachavalpongpun, a professor at Kyoto University's Center for Southeast Asian Studies, expressed that the ceasefire was intrinsically fragile, failing to address internal political motives for conflict.
For Thailand, the renewed fighting acts as a strategic distraction, diverting attention from the caretaker government's mishandling of severe floods and an emerging corruption scandal involving Thai elites and scam networks operating within Cambodia. Under these circumstances, Pavin highlighted that the truce became expendable politically.
In response, Thai military leaders have intensified their stance. The Royal Thai Army's chief of staff has vowed to weaken Cambodia's military capabilities, while Prime Minister Anutin Charnvirakul has stated that diplomatic negotiations are no longer an option, demanding Cambodia follow Thailand's directives to halt the fighting.
Phil Robertson, director of Asia Human Rights and Labour Advocates (AHRLA), remarked that the Kuala Lumpur Peace Accord merely masked underlying disputes without addressing key issues like border demarcation and rising ultra-nationalism.
The roots of the conflict trace back over a century to colonial-era border demarcations by French authorities in 1907, which left four areas, including the contested Preah Vihear temple, undefined. The International Court of Justice ruled in 2013 that the temple belongs to Cambodia, instructing Thailand to withdraw troops, but Thailand continues to reject the court's jurisdiction, keeping the area a flashpoint.
Pavin explained that unresolved territorial claims and weaponized nationalism are at the core of the tensions, with political leaders leveraging border disputes to rally support and maintain a strong security stance, making compromise politically untenable.
Efforts to contain the crisis involve major powers like the U.S., China, and the Association of Southeast Asian Nations (ASEAN). Trump mentioned his intent to intervene, while U.S. Secretary of State Marco Rubio called for an immediate cessation of hostilities. Malaysian Prime Minister Anwar Ibrahim, the current ASEAN chair, has urged both nations to maintain diplomatic engagement, and China has also called for restraint.
Analysts highlight ASEAN's inability to mediate effectively between its members as a significant takeaway. Robertson questioned ASEAN's relevance if it cannot resolve such conflicts. He also noted that external pressures might not sway Thai politicians, who could use them to bolster conservative support domestically.
Pavin emphasized ASEAN's weakness in addressing security crises between its members, necessitating intervention from external powers like Malaysia, the U.S., and China. This failure could lead to a fragmented regional security landscape and economic repercussions from disrupted trade and tourism.
The involvement of major powers now plays a crucial role in mediation and military capacity. With tensions high and nationalism prevalent, analysts predict little chance of a lasting peace soon. Chhengpor Aun, a policy researcher with Cambodia's Future Forum, remarked that the conflict is sustained in Thailand to deflect from domestic political issues, while Cambodia aims to maintain favorable ties with Washington.
He concluded that a challenging period lies ahead for border communities until significant intervention from major powers like Washington or Beijing occurs.
