The UN Security Council rejected a proposal to delay reimposing sanctions on Iran, allowing "snapback sanctions" on its nuclear program to take effect. Russia and China's resolution failed to gain enough support, with Iran's president calling the decision "unfair, unjust and illegal." Western countries insisted on the sanctions due to failed diplomatic efforts. The reinstatement will freeze assets, halt arms deals, and penalize Iran's ballistic missile program, further impacting its economy and increasing regional tensions. Iran stated it would not withdraw from the Nuclear Nonproliferation Treaty despite the sanctions.
