École Française d'Extrême-Orient.

The French School of the Far East, abbreviated EFEO, is an associated college of PSL University dedicated to the study of Asian societies. It was founded on 20 January 1900 with headquarters in Hanoi in what was then the Tonkin protectorate of French Indochina. After the independence of Vietnam, its headquarters were transferred to Phnom Penh in 1957, and subsequently to Paris in 1975. Its main fields of research are archaeology, philology and the study of modern Asian societies. Since 1907, the EFEO has been in charge of conservation work at the archeological site of Angkor.
