The recent clashes between Thailand and Cambodia were sparked by accusations from both sides of breaching a ceasefire agreement. Tensions escalated when Thai soldiers were reportedly attacked by Cambodian troops, leading to Thailand launching airstrikes against military targets in Cambodia. This incident marks a significant resurgence in a long-standing border dispute, particularly around areas like the Tamone Thom temple.
The border dispute between Thailand and Cambodia has been ongoing for over a century, with roots tracing back to colonial-era agreements and differing interpretations of territorial boundaries. The conflict has seen various flare-ups, notably a five-day war in July 2025, which resulted in significant casualties and heightened tensions that have persisted into the current clashes.
Former U.S. President Donald Trump played a pivotal role in attempting to mediate the conflict by brokering a ceasefire agreement between Thailand and Cambodia in October 2025. His administration's involvement aimed to stabilize the region, but the recent escalation of violence suggests that the ceasefire has not been effective, raising questions about the sustainability of such diplomatic efforts.
Both Thailand and Cambodia have historical claims over disputed territories along their 817-km border, particularly around the Preah Vihear temple and surrounding areas. These claims are rooted in colonial history and differing interpretations of maps and treaties. The dispute has been exacerbated by nationalistic sentiments and the significance of these areas to each country's cultural heritage.
Civilians have been significantly affected by the ongoing conflict, with reports indicating casualties and injuries among non-combatants. Recent clashes have triggered mass evacuations in border regions, forcing thousands to flee their homes. The violence has disrupted daily life and raised humanitarian concerns, as both countries grapple with the implications of renewed military actions.
Several ceasefire agreements have been attempted over the years to resolve the Thailand-Cambodia border dispute. The most recent was brokered by Donald Trump in October 2025, following earlier attempts that included international mediation. However, these agreements have often been fragile and short-lived, with both nations frequently accusing each other of violations, leading to renewed hostilities.
Both Thailand and Cambodia possess military capabilities that include ground troops, artillery, and airpower. Thailand has a more advanced military infrastructure, with a larger budget and modern equipment, including fighter jets. Cambodia's military, while smaller, has been involved in various regional conflicts and has received support from allies, underscoring the potential for significant military engagement in border disputes.
The Thailand-Cambodia conflict poses a threat to regional stability in Southeast Asia, as it can lead to increased tensions among neighboring countries. The resurgence of military actions disrupts diplomatic relations and can encourage other territorial disputes in the region. Additionally, the involvement of external powers and the potential for humanitarian crises further complicate the geopolitical landscape.
International responses to the Thailand-Cambodia conflict have included calls for restraint from various countries and organizations. The United Nations and ASEAN have urged both nations to engage in dialogue to resolve their disputes peacefully. However, the effectiveness of these responses is often limited, as both countries prioritize national sovereignty and security over external diplomatic pressures.
Escalation of the conflict between Thailand and Cambodia could lead to significant military confrontations, resulting in increased casualties and further displacement of civilians. It may also destabilize the region, prompting neighboring countries to take sides or intervene. Additionally, a prolonged conflict could undermine international diplomatic efforts and lead to economic repercussions for both nations, affecting trade and investment.
