Latest developments

As part of the Universal Periodic Review conducted by the Human Rights Council, Nepal accepted a recommendation in 2021 to ratify the TPNW.2

Nepal was one of the co-sponsors of the 2021 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'.3

Speaking in the 2021 UN General Assembly's High-Level Plenary Meeting to Commemorate and Promote the International Day for the Total Elimination of Nuclear Weapons, Nepal spoke of the trust deficit among nuclear states and resulting rise in geopolitical tension, and added: 'Amid uncertainty, this year on 22 January, we have witnessed a sliver of hope when the “Treaty on Prohibition of Nuclear Weapons” entered into force despite the apathy in some quarters. [T]he billions of dollars aimed for nuclear programs should be redirected to fight the COVID-19 pandemic and in achieving the SDGs. [...] We call for the strengthening of the NPT, CTBT and TPNW regimes.4


  • Nepal should urgently ratify the TPNW, and continue to encourage other states to adhere to the Treaty.
  • Nepal should conclude and bring into force an Additional Protocol with the IAEA, and upgrade to a Modified Small Quantities Protocol. Nepal should also ratify the CTBT.
