Russia has vetoed a draft resolution by the United States and Japan on non-deployment of weapons of mass destruction in space. This is stated on the UN website.
The resolution was proposed by the USA and Japan. 13 countries out of 15 voted in favor. Russia opposed it, and China abstained.
According to the UN, the resolution would have called on all countries not to develop or deploy nuclear weapons or other weapons of mass destruction in space, which are prohibited by the 1967 international treaty to which the United States and Russia were parties, and to agree to verify compliance.
Russia voted against the resolution after the Security Council failed to include an amendment by Moscow and Beijing calling for a permanent ban on the deployment of any weapons in outer space.
The Russian Foreign Ministry called this the reason for the veto. Moscow has already promised to submit its own draft resolution to the UN to ban the deployment of weapons in space.
