Waging Peace: ASEAN and the Thai-Cambodian Border Conflict

December 2011

International Crisis Group

Abstract

Border clashes between Thailand and Cambodia that caused dozens of casualties and displaced thousands have challenged the Association of South East Asian Nations (ASEAN) to finally turn its rhetoric on peace and security into action. Cambodia’s successful attempt to list the Preah Vihear temple as a World Heritage Site came against the backdrop of turmoil in Thai politics after the 2006 coup that deposed Prime Minister Thaksin Shinawatra. Thai pro-establishment movements used this issue to whip up nationalist sentiments against Cambodia as they tried to topple the Thaksin-backed government. The emotionally-charged campaigns halted border demarcation and sparked a bilateral conflict. In early 2011, the dispute turned into the most violent clash yet between ASEAN’s members, testing its historical commitment to non-aggression and prompting it to get involved. This has raised expectations that it might live up to its stated aspiration to keep peace in its own region. As yet, however, while its engagement set important precedents, it has no significant achievements. More robust diplomacy and leadership are still needed. The resurgence of a largely forgotten 50-year dispute into an active armed conflict was related to two events: the colour-coded struggle in Thailand between the pro-establishment “Yellow Shirts” and the pro-Thaksin “Red Shirts” sparked after Thaksin’s ouster in the September 2006 coup; and the decision of Cambodia to register Preah Vihear as a World Heritage Site, which UNESCO accepted in July 2008. In Cambodia, the listing was occasion for national joy and Khmer pride. In Thailand, the ultra-nationalist Yellow Shirts used it to argue that Thaksin’s proxy administration led by Prime Minister Samak Sundaravej had sold out their motherland and committed treason. It became a powerful weapon to further their agenda, forcing the foreign minister to resign and destabilising the government. They successfully portrayed backing for the listing as a move to further Thaksin’s business interests, despite this policy having been supported by the previous military-installed administration. Until the Yellow Shirts’ attacks, bureaucrats on both sides had seen the listing as a mutual tourism bonanza.
