Debating the Nuclear Weapons Ban Treaty: Regional Perspectives




13:15 Uhr (MEZ)

With its 50th ratification, the Treaty on the Prohibition of Nuclear Weapons (TPNW / Ban Treaty) is soon set to become legally binding. It is a contentious treaty, drafted by a group of 124 non-nuclear-weapon countries in 2017. Since its genesis, it has been boycotted by over 50 states, including all current atomic powers.

Its supporters argue that it brings a new perspective to disarmament negotiations, as well as a binding norm that fills a legal gap which has allowed the continued existence of atomic bombs. Its critics, on the contrary, argue that the treaty is too ambiguous and that it does not create any instruments to ensure effective, verifiable, and permanent atomic disarmament.

This GIGA event, taking place as part of Research Programme 4 on Global Orders and Foreign Policy, will bring together scholars from different regions of the world to discuss the both local and global implications of a binding Ban Treaty. The event embraces perspectives from Africa, Asia-Pacific, Europe, Latin America, and South Asia. Participants will also discuss the consequences of the Ban Treaty for the nuclear non-proliferation and disarmament regime.
