Vietnamese border raids in Thailand

Battle context

The Vietnamese border raids into Thailand were a direct consequence of the collapse of Democratic Kampuchea following the 1978–1979 Vietnamese invasion of Cambodia. After Pol Pot's regime fell, Khmer Rouge forces withdrew into the forested and mountainous border zones along the Cambodia–Thailand frontier, where they regrouped and reorganized with Chinese assistance. The raids reflected Vietnam's effort to suppress this reconstituted threat on Thai territory, drawing Thailand directly into the Cambodian–Vietnamese War. Thai casualties of 10,000–15,000 and the deployment of 120,000–150,000 Thai forces indicate the sustained pressure the border conflict placed on Thailand, transforming what had begun as an internal Cambodian regime change into a regional confrontation involving a neighboring state and its military establishment.
