2008–2011 Cambodian–Thai border crisis
The 2008–2011 Cambodian–Thai border crisis began in June 2008 until December 2011 as part of long-standing territorial dispute between Cambodia and Thailand involving the area surrounding Preah Vihear, an 11th-century Hindu temple in the Dângrêk Mountains, between Choam Khsant District, Preah Vihear province of northern Cambodia and the Kantharalak District, Sisaket Province of northeastern Thailand. According to the Cambodian ambassador to the United Nations, the dispute began on 15 July 2008 when about 50 Thai soldiers moved into the Keo Sikhakirisvara Pagoda vicinity which he claimed was located in Cambodia's territory about 300 metres (980 ft) from Preah Vihear.
