In 2007, Cambodia proposed to the World Heritage Committee's Thirty-First Session that Preah Vihear Sanctuary be listed as a UNESCO World Heritage Site. As Cambodia and Thailand had not resolved border issues concerning the site, the Committee postponed consideration to its 32nd session, and asked Cambodia to provide a complete management plan for the area. Early in January 2008, Cambodia invited Thai experts to participate in a site survey of the Buffer Zone, and then to Siem Reap and Phnom Penh to collaborate with a team of international experts in the making of a plan for the area in Cambodian territory. Thai experts found "unacceptable scientific inaccuracies" in documents presented, dissociated themselves from the group, and then published in rebuttal their own Management Plan for Preah Vihear Mountain and Its Setting. A PDF English language version of the Plan has been released.[4]
