At the conclusion of the 1991 UN enforcement action against Iraq, the Security Council adopted a resolution setting the terms for a cease-fire. The resolution required, among other things, that Iraq “unconditionally accept the destruction, removal, or rendering harmless, under international supervision,” of all chemical and biological weapons, all ballistic missiles with a range greater than 150 kilometers, and associated materials and facilities. Further, the resolution provided for the creation of a UN special commission to carry out “on-site inspection of Iraq's biological, chemical and missile capabilities,” and ordered Iraq to yield such weapons to the commission for “destruction, removal or rendering harmless.” Similar requirements were imposed with respect to the acquisition and development of nuclear weapons. While maintaining the economic sanctions imposed on Iraq after its invasion of Kuwait in August 1990, the Security Council allowed exports to Iraq of foodstuffs and medical supplies (on the condition that a UN sanctions committee had been notified) and also other commodities (if approved by the same committee). The Security Council decided that the sanctions regime would be lifted, however, once Iraq complied with its obligations on the destruction and monitoring of weapons of mass destruction.
