In March 1998 Security Council resolution 1160 established an embargo on the delivery of arms and related matériel of all types, such as weapons and ammunition, military vehicles and equipment and spare parts for the aforementioned, to the territory of the Federal Republic of Yugoslavia, including Kosovo. This was in reaction to the ongoing conflict in Kosovo.
In September 2001 Security Council resolution 1367 lifted the arms embargo after key elements of Resolution 1160 were fulfilled.
