Cambodia has also admitted that it had yet to demarcate the border – including the area where Preah Vihear temple is located – when it signed the memorandum of understanding with Thailand in 2000.

On May 6, the Supreme Court had directed formation of a special team to conduct a survey and demarcate the boundaries of 99 iron ore mines.

The officials said that two engineers from the land acquisition office and one from the forest department had gone to the district to demarcate land and value the trees.
