United Nations Preventive Deployment Force

The United Nations Preventive Deployment Force (UNPREDEP) was established on 31 March 1995 in Security Council Resolution 983 to replace the United Nations Protection Force (UNPROFOR) in the Republic of Macedonia. The mandate of UNPREDEP remained essentially the same: to monitor and report any developments in the border areas which could undermine confidence and stability in the country and threaten its territory. It is widely considered to be an instance of a successful deployment of UN peacekeeping forces in the prevention of conflict and violence against civilians. The operation was shut down on 28 February 1999, after its last extension in Resolution 1186 when China vetoed its renewal in 1999 following Macedonia's diplomatic recognition of Taiwan.
