The complex border conflict between Thailand and Cambodia has deep historical roots, with recent escalations marking one of Southeast Asia’s most serious military confrontations in years. Understanding why Thailand and Cambodia are at war requires examining both historical context and current triggers.
Historical background
The origins of this conflict trace back to colonial-era border treaties from 1904-1907, when France administered Cambodia. The dispute centres primarily around ancient temple complexes along the border, particularly the UNESCO World Heritage site Preah Vihear Temple. Despite a 1962 International Court of Justice ruling granting the temple to Cambodia, border tensions have persisted.
Recent escalation
The current conflict intensified in July 2025 when:
- Cambodian UAVs were spotted near Prasat Ta Muen Thom
- Initial exchanges of artillery fire occurred along the border
- Thailand deployed F-16 fighter jets in response
- Cambodia utilised BM-21 rocket systems
Military actions and casualties
The conflict has resulted in significant military engagement including:
- Thai airstrikes using F-16 fighters
- Heavy artillery exchanges from both sides
- At least 13 civilian casualties on the Thai side
- Extensive damage to infrastructure in border regions
- Deployment of additional troops by both nations
Humanitarian Impact
The border conflict has created a severe humanitarian crisis:
- Over 40,000 civilians evacuated from border areas
- Widespread displacement of local communities
- Damage to civilian infrastructure
- Disruption of local economies and trade
International response
Regional and international bodies have expressed growing concern over the escalating situation:
- ASEAN called for immediate dialogue
- Neighbouring countries urged peaceful resolution
- UN representatives advocated for diplomatic solutions
- International mediators offered assistance
Current status
Both nations continue to blame each other for initiating hostilities, while diplomatic channels remain open but strained. The situation remains volatile with periodic exchanges of fire and ongoing military presence along the border.
