Paper: GS – II, Subject: International Relations, Topic: Global Issues, Issue: Thailand – Cambodia Relations.
Context:
Thailand launched airstrikes on “military targets” in Cambodia after alleging that Cambodian troops killed two Thai soldiers along their disputed border. Cambodia denies initiating fire.
Key Takeaways:
This violence revives a long-running border dispute rooted in colonial-era demarcations.
Origins of the Border Dispute:
Colonial Boundary (1907):
- Border drawn by France (then administering Cambodia) and Siam (Thailand).
- Each country claims the map favoured the other.
- Disputes arise from inconsistent or contested colonial cartography.

Cultural-Historical Claims:
- Both predominantly Theravada Buddhist nations claim cultural ties to disputed regions.
- Each asserts being the “original” or “rightful” cultural owner, intensifying nationalistic tensions.
The Preah Vihear Temple:
- The epicentre of conflict; known as Preah Vihear in Cambodia and Phra Vihan in Thailand.
- Built in 11th–12th century under Khmer Empire; sits atop Dangrek Mountains along the border.
- Symbolic, religious, and strategic importance makes it highly sensitive.
After Independence – Why the Dispute Continued:
- Cambodia and Thailand dispute sovereignty over the temple despite a 1962, International Court of Justice (ICJ) ruling giving it to Cambodia.
- In 2008 tensions rose again when Cambodia sought UNESCO World Heritage status for the temple.
- Thailand objected, calling it a loss of Thai cultural identity and “territorial sovereignty.”

Current Crisis: Why the Conflict Flares:
- Highly nationalistic politics on both sides.
- Ambiguous historical claims due to colonial-era maps.
- Sharp troop presence near the temple area.
- Relatively weak dispute-resolution mechanisms within ASEAN.
- Each clash risks drawing both nations into wider conflict cycles.
BROADER IMPLICATIONS:
Regional Stability:
- Threatens peace in mainland Southeast Asia.
- Disrupts border communities, trade, and cross-border movement.
Colonial Legacy:
- Demonstrates how European-imposed borders continue to cause conflict in Asia.
- Shows long-term effects of ambiguous treaties and inconsistent mapping.
International Law:
- Thailand’s refusal to accept ICJ jurisdiction weakens international adjudication mechanisms.
- Highlights limit of global institutions when states assert sovereignty strongly.
The renewed Thailand–Cambodia clashes show how fragile ceasefires and unresolved colonial borders fuel recurring tensions. Without genuine dialogue, verified de-escalation, and stronger ASEAN mediation, the border will remain a persistent threat to regional stability and civilian safety.
