UN Peacekeeping Force – 1993
1993
Full Implementation 
The mission was unsuccessful in its attempt to disarm the Khmer Rouge and bring them into the democratic process. The Khmer also did not participate in the elections, claiming that they would not do so because Vietnamese troops were still inside Cambodia. However, UNTAC verified that there were no Vietnamese troops inside Cambodia. Except for this allegation and violation of ceasefire by Khmers, the UNTAC maintained reasonable peace and security in other areas and providing security throughout the electoral process. Nearly all of the United Nations military forces, police and civilians left Cambodia by November 15, 1993 after completing their mandate. The estimated costs of the operation were $1.6 billion.1
