The UN Security Council voted unanimously yesterday to lift a three-year-old arms embargo in Yugoslavia, ending the last in a series of military and economic sanctions imposed against the Belgrade government over the past decade. The action marks the UN’s formal recognition that Yugoslavia has embraced democratic rule and cooperated by surrendering former president Slobodan Milosevic in June to a UN war crimes tribunal in the Hague. France and Russia, a close ally of Serbia, Yugoslavia’s dominant republic, led the campaign to end the arms embargo imposed in 1998 to protest Serbia’s military campaign against ethnic Albanians in Kosovo.
