Latest developments

Marking the International Day for the Total Elimination of Nuclear Weapons on 26 September 2022, the Minister of Foreign Affairs of Indonesia, Retno Marsudi, said: ‘Nuclear disarmament must remain a priority for all of us.’ Indonesia looked forward to seeing more signatories to the TPNW, she said. ‘Just like dinosaurs, nuclear weapons must only belong to the past.’2

In the First Committee of the UN General Assembly in October 2022, Indonesia said: ‘In achieving nuclear disarmament, we shall aim for the universalisation of the [TPNW].’3 It also highlighted the successful convening of the 1MSP, noting that ‘This success offered hope in the nuclear disarmament landscape.’4

Indonesia was one of the co-sponsors for the 2022 UN General Assembly resolution on the TPNW, which called upon ‘all States that have not yet done so to sign, ratify, accept, approve or accede to the Treaty at the earliest possible date.'5


  • Indonesia should urgently ratify the TPNW.
