The Thailand-Cambodia border war, also known as the Preah Vihear Temple dispute, was a series of military conflicts that took place between Thailand and Cambodia in the late 2000s and early 2010s. The dispute centered around the ownership and control of the Preah Vihear Temple, a UNESCO World Heritage Site located near the border between the two countries.

The conflict primarily took place in the vicinity of the Preah Vihear Temple, situated on a cliff in the Dangrek Mountains, about 140 kilometers north of the Cambodian capital, Phnom Penh. The temple itself is located on the Cambodian side of the border, but the surrounding territory has been a subject of dispute.

  • Preah Vihear Temple: The ancient Hindu temple, built during the Khmer Empire, is the primary source of the dispute. It's a significant cultural and religious site for Cambodia.
  • Wat Keo Sekha Kirisvarak: A Thai Buddhist temple located near the disputed border area. It was the site of a significant clash between Thai and Cambodian forces in 2008.
  • Khao Phra Wihan: A mountain range in Thailand that borders the Dangrek Mountains. The Thai military established several bases in this area during the conflict.

Historical Background of the Dispute

The border between Thailand and Cambodia has been a subject of dispute for centuries. The current border was established by the Franco-Siamese Treaty of 1904, but the exact location of the border around the Preah Vihear Temple has been a matter of contention. In 1962, the International Court of Justice ruled that the temple belongs to Cambodia, but the surrounding territory was left undecided.

Escalation of Tensions

Tensions escalated in the late 2000s when Cambodia sought to renovate and develop the temple, which Thailand saw as a provocation. In 2008, the United Nations Educational, Scientific and Cultural Organization (UNESCO) inscribed the temple as a World Heritage Site, further inflaming the dispute. This led to a series of military clashes between the two countries, with the most intense fighting occurring in 2008, 2011, and 2012.

The Impact of the Conflict

The conflict had significant impacts on both countries. It resulted in the loss of lives, injuries, and displacement of civilians. The fighting also damaged cultural heritage sites and disrupted the lives of people living in the border areas. The conflict also strained diplomatic relations between Thailand and Cambodia, leading to the recall of ambassadors and the suspension of some bilateral cooperation.

Economic Impact

The conflict had economic repercussions as well. It deterred tourism in the border areas, which are home to several historical and cultural sites. The fighting also disrupted trade and commerce, as the border was closed during the most intense periods of conflict.

The international community, including the United Nations, the Association of Southeast Asian Nations (ASEAN), and other regional organizations, played a significant role in de-escalating the conflict and facilitating a peaceful resolution. In 2011, the two countries agreed to a ceasefire and the withdrawal of their troops from the disputed area. The following year, they established a joint border commission to demarcate the border and prevent further conflicts.

In 2013, the International Court of Justice ruled that the border should be determined by the 1904 treaty, which gave Cambodia the majority of the disputed territory. This ruling was accepted by both countries, and the conflict has been largely resolved since then. However, some issues related to the border and the temple's management remain, and both countries continue to work together to address these issues.
