Belgium may sign and ratify or accede to the TPNW, but will have to make changes to its policies and practices to become compliant.
At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Belgium said: ‘We cannot be satisfied by the current pace of nuclear disarmament. Nuclear-weapon states need to undertake further action. No member of the NPT is exempt from the obligations under Article VI.’1
Four former prime ministers and foreign ministers of Belgium (Willy Claes, Erik Derycke, Yves Leterme and Guy Verhofstadt) were 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.2
- Belgium should renounce the possession and potential use of nuclear weapons on its behalf, end the hosting of foreign nuclear weapons on its territory, and ensure that nuclear weapons do not have a role in its defence posture.
- Belgium should comply with its existing obligation under Article VI of the NPT and pursue negotiations in good faith on nuclear disarmament.
- Belgium 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.
