Cristiani and his delegates in order to find and secure international support for the peace negotiation efforts that were being carried out by his government. Support was actively and officially sanctioned by Venezuela, Mexico, and Spain, who would play an active role, along with the United Nations, in the negotiating process. Domestic policy He was successful in the peace negotiations with the FMLN. The Salvadoran Civil War finally ended on 16 January 1992 with the Chapultepec Peace Accords.
