The UN's Office of the Iraq Programme (OIP), which oversees the oil-for-food scheme, said on 1 April that $1,000 million-worth of signed contracts had been identified for priority delivery to Iraq. The agreements, made with the Baghdad government before war began, cover medicines, foodstuffs, health supplies, drinking water, sanitation, and other essentials. Some of the more than 450 priority contracts are already on their way to the country, while others will be moved up the queue for shipment, in order to ensure that the materials reach Iraq before the 45-day window provided by the revised oil-for-food resolution expires. The new resolution was agreed by UN Security Council members on 28 March. It transfers authority for negotiating contracts from the Baghdad government to UN Secretary-General Kofi Annan.
