Umbrella state (bilateral arrangement with Russia)

Belarus did not participate in the TPNW negotiations in 2017, and has consistently abstained on the annual UN General Assembly resolutions on the Treaty, including in 2023. It may sign and ratify or accede to the TPNW, but will have to make changes to its policies and practices to become compliant. In June 2023, the President of Belarus, Alexander Lukashenko, announced that his country had started taking delivery of Russian tactical nuclear weapons. ‘We have missiles and bombs that we have received from Russia,’ he said in a television interview. ‘The bombs are three times more powerful than those [dropped by the United States on] Hiroshima and Nagasaki.’[1]

Latest developments

Many States, particularly members of NATO, condemned the announced deployment, including in their statements to the First Committee of the UN General Assembly in October 2023.2 Some accused Belarus of breaching its obligations as a non-nuclear-weapon state under the NPT. But Belarus argued that the deployment of Russian tactical nuclear weapons on its territory ‘is carried out within the framework of international law and in strict accordance with the provisions of the NPT’.3

‘Such cooperation is not new, but has long been practised within NATO, both in the form of so-called “joint nuclear missions” and the deployment of US nuclear weapons on the territory of the five non-nuclear member countries of the alliance in Europe,’ it said, referring to Belgium, Germany, Italy, the Netherlands and Türkiye.

At the NPT Preparatory Committee meeting in August 2023, Belarus and Russia said that they ‘share the international community’s desire for a world free of nuclear weapons’ and described the NPT as ‘extremely important for strengthening global security and ensuring strategic stability’.4


  • Belarus 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.

  • Belarus should comply with its existing obligation under Article VI of the NPT and pursue negotiations in good faith on nuclear disarmament.

  • Belarus 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.

  • Belarus should bring into force its Additional Protocol with the IAEA.
