UN Security Council passes Resolution 1737 imposing first nuclear sanctions on Iran

The UN Security Council unanimously votes to impose its first mandatory sanctions against Iran's nuclear program under Resolution 1737. The resolution calls on Iran to suspend uranium enrichment and reprocessing activities and grants the IAEA expanded inspection rights. It freezes assets of Iranian officials involved in the nuclear program and bans arms sales to Iran. The move shifts nuclear diplomacy from diplomatic persuasion to coercive economic pressure and establishes the foundation for the sanctions regime that will follow over the next decade.
