 After King Sihanouk abdicated, the new king Sihamoni, Yuvaneath's younger stepbrother, appointed Yuvaneath the Supreme Royal Advisor.In this capacity, Yuvaneath proclaimed his opposition to the tribunal of former Khmer Rouge leaders, believing that the 1975-1979 turmoil resulting in the massacre of over 2 million Cambodians was a result of foreign intervention by the Vietnamese and Thai governments.Yuvaneath also stated his belief that a trial would be contrary to the interests of national reconciliation.
