Updates on the situation along the Cambodia-Thailand border regarding the case of the Thai military forces continued their armed aggression on Cambodia, in the 4th and 5th Military Regions on December 21, 2025 which enters the 15th day:
The Thai side has continuously violated the ceasefire and the “Joint Declaration signed by the Prime Ministers of the Kingdom of Cambodia and the Kingdom of Thailand” on October 26, 2025.
1. The frontline situation at the 4th Military Region Oddar Meanchey and Preah Vihear provinces: The Thai military continued its attack to invade Cambodian sovereign territory: From 5:00pm on December 20 to 10:00am on December 21, 2025:

2. The frontline situation at the 5th Military Region in Banteay Meanchey province: The Thai military continued its attack to invade Cambodian sovereign territory: From 12:00am until 10:00am on December 21, 2025:
– At 5:50am, the Thai military fired shells into the area of Boeung Trokoun.

The Ministry of National Defence of Cambodia wishes to reiterate that “Cambodia’s rights to self-defence is solely targeted at the Thai military targets and has never targeted at civilian areas”. Conversely, the Thai side has deliberately attacked locations where Cambodian civilians reside, resulted in 19 deaths (including 1 infant) and injuries to 79 innocent Cambodian civilians, as of 6:00pm December 20, 2025.
Time and time again, the Thai military has utilized deceptive tactics to mask its violations of Cambodia’s sovereignty and territorial integrity, in blatant defiance of established international legal frameworks. The Thai military’s systemic aggression against Cambodia characterized by the deployment of heavy weaponry, including F-16 fighter jets, naval warships, heavy artillery, cluster bombs, toxic gas, and all type of advanced drones, constitutes a direct assault on both innocent civilians and sites of the world cultural heritage. Such conduct identifies Thailand as a state that destroys peace and security, not only between Cambodia and the entire region, but also to serve its expansionist ambitions and aggression against smaller and weaker countries. We demand that the Thai military immediately cease its campaign of systemic misinformation and distortions. The path toward peace requires an immediate cessation of hostilities, strict adherence to the ceasefire, and the full reimplementation of the Joint Declaration on the Peace Agreement between Cambodia and Thailand. The Thai leadership must now demonstrate its sincerity, transparency, and commitment to international laws through responsible action rather than hollow rhetoric and deceptions.
In this sense, Cambodia calls on the international community to strongly condemn Thailand’s violations of the Joint Declaration and its repeated war crimes and unlawful activities, as well as demands that Thailand must take full responsibility for such brazen violations. Cambodia urges that Thailand immediately stop all hostile activities and withdraw its forces from Cambodia’s territorial integrity, and avoid acts of incursion and aggression that threaten peace and stability in the region as a whole.
It is also important to stress that as of now the heroic Cambodian Army and National Police forces will continue to stand strong, brave and steadfast in their fight against the aggressor and always remain vigilant to exercise our rights to self-defence as enshrined in the international legal instruments in the fulfillment of their duties to defend and protect at all costs the Cambodian territorial integrity and people.
