The border dispute between Thailand and Cambodia has historical roots dating back over a century, primarily centered around territorial claims near the Preah Vihear Temple and other areas. Both nations have contested sovereignty along their 817-km land border, leading to multiple confrontations, particularly in the context of nationalism and colonial legacies. The conflict intensified in 2008 when the temple was granted UNESCO World Heritage status, reigniting nationalistic sentiments and military skirmishes.
The ceasefire agreement between Thailand and Cambodia was brokered by U.S. President Donald Trump and Malaysian Prime Minister Anwar Ibrahim in October 2025, following a five-day conflict in July that resulted in numerous casualties. However, the recent escalation in December indicates a breakdown of this agreement, with both sides accusing each other of breaching the truce. The evolving situation highlights the fragility of peace in the region, as past agreements have often failed to hold.
Donald Trump played a significant role in brokering the ceasefire agreement between Thailand and Cambodia in October 2025. His administration facilitated diplomatic discussions aimed at reducing tensions and preventing further military conflict after a violent outbreak in July. Trump’s involvement underscored the United States' interest in maintaining stability in Southeast Asia, though the recent resurgence of hostilities suggests that his efforts may not have led to a lasting peace.
The renewed conflict between Thailand and Cambodia has serious implications for regional stability in Southeast Asia. Ongoing military actions could lead to a broader escalation, drawing in neighboring countries and affecting trade routes. The instability may also hinder diplomatic relations and economic cooperation within ASEAN. Additionally, the conflict raises concerns about humanitarian impacts on local populations, potentially resulting in displacement and increased tensions among communities along the border.
Both Thailand and Cambodia assert strong claims over their respective territories, viewing the disputed areas as integral to their national identity and sovereignty. Thailand traditionally emphasizes its historical boundaries and military presence, while Cambodia relies on international recognition of its claims, particularly regarding sites like the Preah Vihear Temple. This mutual insistence on sovereignty complicates diplomatic negotiations and fuels nationalistic sentiments, making compromise challenging.
The ongoing conflict between Thailand and Cambodia significantly impacts local civilians, particularly those living near the border. Civilians face the threat of violence, displacement, and loss of livelihoods due to military operations. Reports indicate that clashes and airstrikes have led to casualties among non-combatants, as well as disruptions to daily life and access to essential services. The humanitarian situation can worsen if fighting escalates, leading to a refugee crisis and increased poverty.
Thailand possesses a more advanced military compared to Cambodia, with a larger budget, modern equipment, and a well-trained army. Thailand's military capabilities include advanced aircraft, artillery, and naval forces. In contrast, Cambodia's military is smaller and less equipped, relying on outdated technology. However, Cambodia has been increasing its defense spending and modernizing its forces in recent years. The disparity in military strength influences their confrontations and negotiations.
International reactions to the Thailand-Cambodia conflict have varied, with calls for restraint from global powers and regional organizations like ASEAN. The involvement of the U.S. in brokering the ceasefire reflects its strategic interests in Southeast Asia. However, the lack of decisive international intervention during escalations has allowed tensions to persist. Media coverage and diplomatic statements can influence public perception and pressure both governments to seek peaceful resolutions.
Thailand and Cambodia have a history of conflicts, with notable clashes occurring in 2008 over the Preah Vihear Temple, leading to military confrontations. The border dispute escalated into a five-day armed conflict in July 2025, resulting in casualties on both sides. These past incidents highlight the longstanding tensions rooted in historical grievances and territorial claims, contributing to the current cycle of violence and hostility.
Currently, diplomatic efforts focus on de-escalating tensions and restoring the ceasefire between Thailand and Cambodia. Both countries have engaged in discussions facilitated by ASEAN and international actors, aiming to address grievances and prevent further military actions. However, the recent resurgence of hostilities poses challenges to these efforts, as both nations remain entrenched in their positions. Continued dialogue and pressure from the international community may be essential to achieving lasting peace.
