UNAMIC was established in October 1991 to assist the Cambodian Parties to facilitate communications between the military headquarters of the four Cambodian Parties in matters relating to the cease-fire and to undertake a mine-awareness training role. Subsequently, this mandate was extended to include training in mine clearance and the initiation of a de-mining programme. The mandate for this Mission expired in March 1992 with the establishment of the United Nations Transitional Authority in Cambodia.
