Nuclear Ban Treaty Negotiations 2017

Nuclear ban treaty negotiations in 2017

Did you know that nuclear weapons are the only weapons of mass destruction not yet prohibited in a comprehensive and universal manner despite their well-documented impacts? Biological weapons, chemical weapons, landmines and cluster munitions have all been explicitly and completely banned under international law. 

In one of its final acts of 2016, the United Nations General Assembly adopted with overwhelming support a landmark resolution to begin negotiations on a treaty banning nuclear weapons. This historic decision heralds an end to two decades of paralysis in multilateral nuclear disarmament efforts.

The first round of negotiations on a treaty to ban nuclear weapons under international law took place in New York from 27-31 March 2017. The session revealed that the 132 countries participating shared a vision for a world without nuclear weapons. And while some disagreement was expected, there was broad agreement among many countries on most elements of the proposed treaty.

The next session of negotiations began on 15 June 2017 and are scheduled to end on 7 July 2017. To follow the negotiations and to get daily updates, you can visit Reaching Critical Will’s website.
