Latest developments

The chairman of the International Affairs Committee of the National Assembly, Waven William, said that Seychelles also had rallied to get other countries to ratify this treaty as soon as possible.2

In the 2021 UN General Assembly, Seychelles associated itself with a statement on the First Commitee by the African Group, which said: 'Given the slow progress and frustration that has characterized nuclear disarmament for so many years, The TPNW marks a watershed in the drive to rid the world of nuclear weapons. [...] It is our hope that the nuclear weapon states and those under the so-called nuclear umbrella would seize this opportunity to sign and ratify the treaty as well as pursuit the goal of a nuclear weapon free world'.3


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