South Korea voted against the UN General Assembly resolutions on the TPNW in 2018, 2019, and 2020. In the words of the South Korean delegation to the 2018 NPT Preparatory Committee, the TPNW, 'crafted without the participation of nuclear-weapon states cannot but bear intrinsic limitation.' 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.

- South Korea should ensure that nuclear weapons do not have a role in its national defence plans and security policies. It should renounce the retention and potential use of nuclear weapons on its behalf, for instance through a declaratory statement, and refrain from endorsing future alliance statements in support of weapons of mass destruction.
- South Korea should urgently sign and ratify the TPNW, and encourage other states to adhere to the Treaty. Until it is in a position to do so, it should welcome the TPNW as a valuable contribution to the global disarmament and non-proliferation architecture, attend its meetings of states parties as an observer, and work with its states parties on practical steps towards disarmament.
