Latest developments

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, El Salvador celebrated the fact that earlier in the year Central America became ‘the first region in the world to fully ratify this important nuclear disarmament instrument’, reflecting the political will of Central American states to support multilateral efforts for peace and security. El Salvador also emphasised that the TPNW and NPT are complementary, with the TPNW contributing to implementation of Article VI of the NPT. ‘For our country, the humanitarian consequences derived from the use of nuclear weapons are catastrophic, which is why we advocate their complete prohibition and their total elimination,’ it added.2

In a closing statement to the NPT Review Conference, El Salvador and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.3

In the First Committee of the UN General Assembly in October 2022, El Salvador expressed support for the Vienna Action Plan adopted at the 1MSP. ‘We call on those states that have not yet done so to ratify or accede to [the TPNW] as soon as possible,’ it said.4


  • El Salvador should continue to encourage other states to adhere to the TPNW.

  • El Salvador should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
