Work resumed after the end of the Cambodian Civil War and, since 1993, has been jointly co-ordinated by India, Germany, Japan and UNESCO through the International Co-ordinating Committee on the Safeguarding and Development of the Historic Site of Angkor (ICC), while Cambodian work is carried out by the Authority for the Protection and Management of Angkor and the Region of Siem Reap (APSARA), created in 1995. Some temples have been carefully taken apart stone by stone and reassembled on concrete foundations, in accordance with the method of anastylosis. World Monuments Fund has aided Preah Khan, the Churning of the Sea of Milk (a 49-meter-long bas-relief frieze in Angkor Wat), Ta Som, and Phnom Bakheng. International tourism to Angkor has increased significantly in recent years, with visitor numbers reaching around 2 million a year by 2014; this poses additional conservation problems but has also provided financial assistance to the restoration effort.
