The CTBT bans all nuclear explosions. The Treaty hampers both the initial development of nuclear weapons as well as the upgrade of existing designs. The Treaty also helps prevent damage caused by nuclear testing to humans and the environment.

The Treaty has been signed by 182 States and ratified by 154. However, the CTBT's stringent entry-into- force formula proscribes that 44 particular States need to ratify the Treaty for it to enter into force. These States possessed nuclear capabilities at the time of the Treaty negotiations in the mid-1990s. Nine of them have yet to ratify: China, the Democratic People's Republic of Korea (DPRK), Egypt, India, Indonesia, Iran, Israel, Pakistan and the United States (the DPRK, India and Pakistan have also not yet signed the Treaty).

The Ministerial Conference on 23 September will adopt a Final Declaration deciding on concrete actions to promote the Treaty's entry into force will be adopted, aiming in particular at the above-mentioned nine.

The establishment of the CTBT verification regime to monitor the globe for nuclear explosions has progressed significantly since the last conference in 2009. A total of 285 of the planned 337 International Monitoring System facilities are now operational. The monitoring system detected the DPRK nuclear tests in 2006 and 2009 in a fast and reliable manner. The system can also assist with disaster mitigation measures, in particular tsunami warning and radiation detection, as was the case with the March 2011 earthquake and tsunami in Japan.

On the occasion of the International Day against Nuclear Tests on 29 August 2011, the UN Secretary General declared:

"I urge all States that have not yet signed or ratified the Treaty to do so as a matter of priority.  Achieving that goal would further reinforce the growing movement for a nuclear-weapon-free world.  Every day, more and more people are viewing both nuclear tests and nuclear weapons as dangerous relics of the cold war, long-overdue for permanent retirement. On this International Day against Nuclear Tests, I call on all States to take a bold step towards a safer and saner world for all."
