Cambodia-Thailand Border Conflict: Multi-Dimensional Analysis for UPSC

By Suryavanshi IAS

The Cambodia-Thailand conflict over Preah Vihear Temple is a complex issue with historical, geopolitical, legal, and humanitarian dimensions. For UPSC aspirants, a multi-angle approach is essential to tackle related questions in Prelims, Mains (GS-II – International Relations), and Essay papers.

1. Historical Angle

Key Points:

Khmer Empire Legacy: The temple was built in the 11th century during the peak of the Khmer Empire, which also constructed Angkor Wat.

Colonial Treaties:

1904 & 1907 French-Siamese Treaties: France (protector of Cambodia) and Siam (Thailand) demarcated borders, placing Preah Vihear under Cambodia.

1954 Thai Occupation: After Cambodia’s independence, Thailand briefly occupied the temple, leading to the 1962 ICJ case.

1962 ICJ Verdict: Ruled in favor of Cambodia but left access disputes unresolved, fueling future clashes.

UNESCO Listing (2008): Cambodia’s successful bid triggered Thai backlash, leading to military standoffs in 2008 & 2011.

UPSC Relevance:

Prelims: Questions on Khmer Empire, colonial treaties, ICJ rulings.

Mains: "How do historical disputes shape modern geopolitics? Discuss with reference to the Preah Vihear conflict."

2. Geopolitical Angle

Key Points:

Nationalism & Domestic Politics:

Both countries use the dispute to stoke nationalist sentiments.

2025 Leaked Call: Thai PM’s dismissal shows how domestic politics fuels conflict.

ASEAN’s Role:

Limited intervention due to ASEAN’s non-interference principle.

Malaysia’s mediation (2025) highlights regional diplomacy.

China’s Influence:

Cambodia leans towards China, while Thailand balances US & China, adding strategic complexity.

UPSC Relevance:

Mains: "Critically examine ASEAN’s effectiveness in resolving regional conflicts."

Essay: "Nationalism vs. Regional Cooperation in South-East Asia."

3. Legal Angle

Key Points:

ICJ’s Role:

1962 Ruling: Granted temple sovereignty to Cambodia but left border demarcation vague.

2013 Interpretation: Clarified that surrounding area also belongs to Cambodia, ordering Thai withdrawal.

Enforcement Challenges:

Thailand partially complied, maintaining troops near the temple.

Shows limitations of international law without strong enforcement.

UPSC Relevance:

Prelims: Questions on ICJ’s jurisdiction.

Mains: "How effective is the ICJ in resolving territorial disputes? Discuss with examples."

4. Humanitarian Angle

Key Points:

Civilian Impact:

2025 Clashes: 25+ deaths (military & civilians), 2,78,000+ displaced.

Artillery on civilian zones violates International Humanitarian Law (IHL).

Landmines & Displacement:

Thai soldiers injured by landmines (July 2025)—remnants of past wars.

Long-term refugee crisis in border areas.

UPSC Relevance:

Mains: "Examine the humanitarian consequences of border conflicts in South Asia."

Ethics (GS-IV): "Should national security override humanitarian concerns in territorial disputes?"

Conclusion & Way Forward

Diplomatic Solutions: Strengthening ASEAN-led mediation and bilateral talks.

Demilitarization: Implementing ICJ’s 2013 demilitarization order.

Humanitarian Aid: Cross-border cooperation for refugee rehabilitation.

📌 UPSC Takeaways:
