The conflict situation along the Thailand-Cambodia border in 2025-2026 is being described as a potential trigger for a "third round of war," with details as follows.
Tensions have reignited due to multiple overlapping factors:
Territorial claims over overlapping areas: Reports of confrontations in the "Emerald Triangle" (the junction of Thailand, Laos, and Cambodia) and near Ta Kwai Temple in Surin Province, with both sides accusing the other of encroaching on operational boundaries.
Triggers from minor clashes: On 24 July 2025, fighting occurred at multiple points, reportedly more intense than in 2011, involving artillery and heavy weapons, leading to a subsequent ceasefire declaration.
Issues surrounding the 2001 MOU and maritime areas: Political currents in Thailand have called for cancellation of the 2001 Memorandum of Understanding (MOU) concerning overlapping maritime zones, due to sovereignty concerns, which has caused dissatisfaction in Cambodia.
Internal politics: Analysts believe both countries might be leveraging border disputes to fuel nationalist sentiment, especially Cambodia, which moved troops near the border ahead of elections.
Headings. | Thai military. | Cambodian military. |
Technology. | Has a strong advantage, particularly in the use of suicide drones and AI surveillance systems, along with an air force equipped with F-16s. | Focuses on procuring new heavy weapons and air defense systems, as well as accumulating military equipment along the border. |
Personnel. | Emphasizes improving strongholds and using technology to reduce losses, strictly adhering to operational boundaries. | Deploys forces nearby (especially at Ta Kwai Temple) and focuses on training and reviewing lessons from past conflicts. |
Attitudes. | "Cautious but not seeking conflict," affirming sovereignty defense while emphasizing negotiations through the Regional Border Committee (RBC). | "Denies preparation for war," but military movements seen by Thailand as concerning signals. |
The new wave of clashes in 2025 caused alarming damage as follows:
Thai side: Military personnel suffered deaths and injuries from clashes and landmines (for example, the November 2025 incident in Sisaket Province where two Thai soldiers were seriously injured), with a total cumulative loss of 46 personnel commemorated in 2026.
Cambodian side: Reports of military deaths in minor clashes, such as one soldier killed in the Emerald Triangle in May 2025, and other major clashes resulting in several dozen casualties.
Civilians: Over 800,000 border residents were displaced during heavy fighting in July 2025. Public facilities in Thailand, such as hospitals and gas stations, were damaged by BM-21 rocket fire.
Despite rumors of a "third round" after the rainy season, both sides remain cautious. The Thai military states it "sees some signs but is not overly concerned," while Cambodia continues to deny invasion preparations. However, tensions over the cancellation of MOU 43 or MOU 44 remain a ticking time bomb that requires close monitoring.
