The international community helped install a Government of Unity and National Reconciliation in April 1997, but UNITA did not allow the regional MPLA government to take up residence in 60 cities. The UN Security Council voted on 28 August 1997, to impose sanctions on UNITA through Resolution 1127, prohibiting UNITA leaders from traveling abroad, closing UNITA's embassies abroad, and making UNITA-controlled areas a no-fly zone. The Security Council expanded the sanctions through Resolution 1173 on 12 June 1998, requiring government certification for the purchase of Angolan diamonds and freezing UNITA's bank accounts.
