Latest developments

In a statement to the First Committee of the 2021 UN General Assembly, Nicaragua said: 'Nicaragua once again takes advantage of this opportunity to insist before the international community the importance to move once and for all towards disarmament general and complete, in which the highest priority remains the elimination of nuclear weapons. The greatest desire of the inhabitants of Mother Earth is that the nuclear weapons that are a threat disappear for the entire Humanity, including for the Peoples of the countries that manufacture and own them. We welcome the entry into force of the historic Treaty on the Prohibition of Weapons Nuclear, which prohibits for the first time the existence, use and threat of use of nuclear weapons, which Nicaragua has ratified. We will continue to state that there is no Plan B to save Mother Earth from a nuclear catastrophe, the sole guarantee to prevent the use or threat of the weapons of mass destruction and their non-proliferation, is the total and absolute elimination of nuclear weapons.2


  • Nicaragua should continue to encourage other states to adhere to the TPNW.
  • Nicaragua should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
