UNSC approves resolution for global implementation CTBT to ban nuclear weapons tests

The United Nations Security Council (UNSC) has approved a resolution urging quick global implementation of Comprehensive Nuclear-Test-Ban treaty (CTBT) to ban tests of nuclear weapons.

The resolution has welcomed progress made towards universalization of the Treaty with 14 votes in favour of it and one abstention (Egypt).

Key Facts

  • The CTBT bans all nuclear explosions for both civilian and military purposes. It was adopted by the UNGA under resolution 50 (1996).
  • The Treaty will enter into force 180 days after the date of deposit of the instruments of ratification by all.
  • So far, 183 countries have signed the CTBT and 166 States have deposited their instruments of ratification.
  • The treaty already has a network of monitoring stations but does not have power to go on site to inspect for tests until it enters into force.
  • But for that, the holdouts among the 44 countries that are designated nuclear capable, the United States, Egypt, China, India, Israel, Iran, North Korea and Pakistan must ratify it.


29 August: International Day Against Nuclear Tests

The International Day Against Nuclear Tests is observed on 29 August across the world to raise awareness about the effects of nuclear weapon test explosions or any other nuclear explosions.

Observance of the day calls for the urgent need to prevent nuclear catastrophes to avert devastating effects on humankind, the environment and the planet. It also highlights urgent need for cessation of nuclear weapons as one of the means of achieving the goal of a nuclear-weapon-free world.

On this day various events are organised across the world such as symposia, conferences, exhibits, competitions, publications, instruction in academic institutions, media broadcasts etc.
