 UNTAET exercised administrative authority over East Timor during the transition to independence.The United Nations Mission of Support in East Timor (UNMISET) (May 2002—May 2005), also a peacekeeping mission, was mandated to provide assistance to the newly independent East Timor until all operational responsibilities were fully devolved to the East Timor authorities, and to permit the new nation, now called Timor-Leste, to attain self-sufficiency.Once the peacekeeping mission withdrew, a new political mission, the United Nations Office in East Timor (UNOTIL) (May 2005—August 2006), supported the development of critical State institutions and the police and provided training in observance of democratic governance and human rights.
