evidence: "Preah Vihear belongs to neither Cambodia nor Thailand – it belongs to sacred powers. It has been a holy place for pilgrimage," said anthropologist and archaeologist Srisakra Vallibhotama. [...] Established in the reign of Cambodian King Yasovarman (889-900) under the Devaraja (divine kingship) Cult, Preah Vihear stands on the Peuy Ta Di cliff of the Phra Viharn Mountain. The mountain is part of the Phanom Dong Rek Range that lies between the Lower Khmer Plain and the Korat Plateau. [...] To prove that the Phra Viharn sanctuary compound, from the foot of the mountain to the top, is in Thai territory, just pour water from the top of the mountain and see on which side it drains. The fact is that the water flows towards Korat Plateau and to the Lam Trao reservoir in Si Sa Ket, Srisakra noted.
