Russia has vetoed a UN resolution sponsored by the United States and Japan calling on all nations to prevent a dangerous nuclear arms race in outer space. The vote in the 15-member Security Council on April 24 was 13 in favor, with Russia opposed and China abstaining. The resolution calls on all countries not to develop or deploy nuclear arms or other weapons of mass destruction in space, as banned under a 1967 international treaty that included the United States and Russia, and to agree to the need to verify compliance.
