Unfortunately, much of these works completely ceased to exist during the Khmer Rouge dictatorship. Artisans ware instead forced to work in labour camps, where most of them died painful deaths. Many arts and crafts also purposely perished during that time.
Today there has been a revival, due to a great deal of restoration work, which has been initiated by the Royal governments of the Kingdom of Cambodia. Now many centers have been established to keep the ancient methods of the craftwork alive. You can see examples of this throughout the country.
