Comprehensive Nuclear Test-Ban Treaty

07 November 2023

Statement attributable to the Spokesperson for the Secretary-General on 6 November 2023

The Secretary-General deeply regrets the decision by the Russian Federation to revoke its ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Since the Treaty’s adoption, Russia has been a leader in seeking to bring the CTBT into force. It is concerning to see a reversal of this trend.   

The CTBT is critical for international peace and security. It is an essential element of a world free of nuclear weapons.

All States, particularly those whose ratification is required for the Treaty's entry into force, should ratify the CTBT without delay or preconditions. In the interim, the nuclear-weapon States should jointly reaffirm their testing moratoriums and commit not to take any actions that would defeat the object and purpose of the treaty.
