Nuclear weapons - strengthened monitoring and verification
It entered into force on 13 November 2012.
The CTBT was negotiated between 1994 and 1996 and has since been ratified by 163 countries. However, key nuclear countries like the USA and China have yet to ratify the Treaty, thus preventing it from coming into force. Until it becomes law, the Preparatory Commission of the CTBTO helps build up the Treaty and prepare its verification regime.
* The CTBT's verification regime is designed to detect any nuclear explosion on Earth. It uses an International Monitoring System (IMS) and 4 verification technologies to monitor countries’ compliance with the CTBT, which bans all nuclear explosions on the planet.
