In the initial aftermath of the breakup of Yugoslavia, Mexico maintained its diplomatic relations with newly established Federal Republic of Yugoslavia (Serbia and Montenegro) but reduced its level to the charge d'affaires due to host country involvement in Bosnian War.[1] Following the United Nations Security Council Resolution 757 Mexico refused the entry of any Yugoslav official and banned its government officials from traveling to Federal Republic of Yugoslavia.[1] Mexico however maintained its embassy in Belgrade and established formal relations with Serbia and Montenegro and other successor states.[1]
