On March 31, 2006, the mandate of AMIS would have run out, with the African Union force already on the ground to be incorporated into a UN peacekeeping mission. Nevertheless, during a March 10, 2006 meeting of the African Union's Peace and Security Council, the Council decided to expand the mission for six months until 30 September 2006. On August 31, after United Nations Security Council Resolution 1706 failed to see the implementation of its proposed UN peacekeeping force of 20,000 due to opposition from the government of Sudan, on October 2 the AU extended AMIS' mandate further, until December 31, 2006, and then again until June 30, 2007.
