Latest developments
South Korea may sign and ratify or accede to the TPNW, but will have to make changes to its policies and practices to become compliant.
Ban Ki-moon, a former foreign minister of South Korea and a former UN secretary-general, was among the signatories to an open letter in September 2020 calling on current leaders in umbrella states to 'show courage and boldness' and join the TPNW.1
Recommendations
- South Korea should ensure that nuclear weapons do not have a role in its national defence plans and security policies. It should renounce the possession and potential use of nuclear weapons on its behalf, for instance through a declaratory statement, and refrain from endorsing future statements in support of weapons of mass destruction.
- South Korea should urgently adhere to the TPNW. Until it is in a position to do so, it should welcome the TPNW as a valuable component in the global disarmament and non-proliferation architecture, work with the Treaty's states parties on practical steps towards disarmament, and attend the meetings of states parties as an observer.
