December 23, 2006: United Nations Security Council Resolution 1737 was unanimously passed by the United Nations Security Council. The resolution, sponsored by France, Germany and the United Kingdom, imposed sanctions against Iran for failing to stop its uranium enrichment program following resolution 1696. It banned the supply of nuclear-related technology and materials and froze the assets of key individuals and companies related to the enrichment program. The resolution came after the rejection of UN economic incentives for Iran to halt their nuclear enrichment program. The sanctions will be lifted if Iran suspends the "suspect activities" within 60 days to the satisfaction of the International Atomic Energy Agency.
