The latest conflict between Thailand and Cambodia was triggered by renewed border hostilities, with both countries accusing each other of ceasefire violations. Tensions escalated when Thailand launched airstrikes against Cambodia, aiming to cripple its military capabilities. This violence has reignited long-standing territorial disputes along their undemarcated 817-km border, which have persisted for over a century.
The U.S. has played a mediating role in the Thailand-Cambodia conflict, particularly through Donald Trump, who brokered a previous ceasefire. As fighting escalated, Trump expressed his intention to intervene again, stating he would make a phone call to address the situation. However, Thailand has ruled out further mediation by the U.S., indicating a complex dynamic in international involvement.
The historical disputes between Thailand and Cambodia primarily revolve around territorial claims, particularly over the Preah Vihear Temple and surrounding areas. These disputes date back to colonial times and have led to military confrontations, including a significant flare-up in 2011. Both nations have a long history of nationalist sentiments that complicate negotiations and foster ongoing tensions.
The humanitarian impacts of the fighting have been severe, with hundreds of thousands of people displaced from their homes. Renewed clashes have resulted in civilian casualties, including deaths and injuries. The conflict has strained resources, leading to poor living conditions for evacuees and raising concerns about access to food, shelter, and medical care for those affected.
Land mines, particularly those from the Khmer Rouge era, significantly affect the conflict dynamics between Thailand and Cambodia. In 2025, reports indicated that Thai soldiers were injured by these mines, with some losing limbs. The presence of unexploded ordnance complicates military operations and poses a continuous threat to civilians, hindering peace efforts and exacerbating humanitarian crises.
International diplomacy plays a crucial role in attempting to de-escalate tensions between Thailand and Cambodia. Efforts by the U.S. and other nations to mediate conflicts aim to prevent further violence and promote dialogue. However, the effectiveness of these diplomatic interventions is challenged by nationalistic sentiments and the complexities of historical grievances, which often hinder lasting resolutions.
The ongoing conflict between Thailand and Cambodia has significant economic implications, particularly for regional trade and investment. As fighting disrupts border crossings and affects supply chains, industries such as apparel sourcing may suffer. The instability can deter foreign investment and tourism, further straining the economies of both nations, which rely on these sectors for growth.
Civilians have been profoundly affected by the violence, facing displacement, loss of life, and injuries. Reports indicate that many have fled their homes, with hundreds of thousands affected by the conflict. The psychological toll, along with the disruption of basic services like healthcare and education, further exacerbates the humanitarian crisis, leaving many in vulnerable situations.
Key ceasefire agreements in the Thailand-Cambodia conflict have aimed to halt hostilities and promote peace. The most notable was brokered by Donald Trump, which initially aimed to reduce tensions along the border. However, the fragility of these agreements is evident, as recent violations and renewed fighting have highlighted the challenges in maintaining peace and the need for effective enforcement mechanisms.
To achieve peace, strategies could include renewed diplomatic efforts involving neutral third parties to mediate discussions, confidence-building measures between military forces, and addressing underlying historical grievances. Additionally, establishing a joint task force for border management and humanitarian aid could help alleviate the immediate impacts of conflict while paving the way for long-term negotiations.
