What is the Treaty on the Prohibition of Nuclear Weapons?
The Treaty on the Prohibition of Nuclear Weapons was adopted in July 2017 at the United Nations with 122 countries voting in favor. It bans the use, threat of use, development, production, manufacture, acquisition, possession, stockpiling, transfer, stationing, deployment or installation of nuclear weapons, as well as assistance with, encouragement or inducement of any of these prohibited activities. The treaty also includes positive obligations requiring states parties with people or places harmed by nuclear weapons use or testing under their jurisdiction to provide assistance and requires all states parties in a position to do so to also help these efforts. The treaty strengthens the norm against nuclear weapons as the first legal instrument to ban them.
