Iran voted in favour of adopting the TPNW at the UN Diplomatic Conference in 2017 and has consistently voted in favour of the annual UN General Assembly resolutions on the treaty, including in 2021.
Following the US withdrawal from the Joint Comprehensive Plan of Action (JCPOA), Iran restarted uranium enrichment beyond levels previously permitted by the agreement. As of the end of 2021, Iran had effectively reduced its potential nuclear breakout time from approximately a year under the JCPOA to just a couple of months, although there is currently little public indication that Tehran intends to take that highly consequential step at this time. It is particularly concerning, however, that since February 2021 Iran has refused to allow the IAEA access to a facility where advanced centrifuge components are being produced. As of writing, the United States and the remaining parties to the JCPOA were in the midst of negotiations over a potential US return to the deal (or perhaps the conclusion of a new interim deal).
In the First Committee of the 2021 UN General Assembly, Iran said of the TPNW: 'The adoption of this treaty was a right step in the right direction. As such, we continue to support its overall objective. The TPNW complements the NPT. However, the TPNW should also be complemented by the urgent commencement of negotiations and the conclusion of a comprehensive convention on nuclear weapons, leading to the total elimination of all nuclear weapons in a verifiable and irreversible manner. The entry into force of the treaty from 2021, is considered a successful achievement for the global movement towards nuclear disarmament.'1
- Iran should urgently adhere to the TPNW.
- Iran should return to compliance with the JCPOA, and bring into force its Additional Protocol with the IAEA. Iran should also ratify the CTBT.
