Mauritius
It is believed that the question of whether Mauritius will adhere to the TPNW was still under consideration in the government in 2023. Mauritius voted in favour of the adoption of the TPNW in the UN Diplomatic Meeting in 2017 and has consistently voted in favor of the annual UN General Assembly resolutions on the Treaty, including in 2023. Mauritius maintains policies and practices that are compatible with all of the prohibitions in Article 1 of the TPNW, and can therefore sign and ratify or accede to the Treaty without the need for a change in conduct.

Latest developments
In January 2023, Mauritius participated in an African regional seminar on universalisation of the TPNW in Pretoria, hosted by the South African foreign ministry.1
Mauritius has previously noted the problem of the colonial administration of the Chagos Islands by the United Kingdom and Mauritius' lack of control over this archipelago, which includes a US air base on Diego Garcia. This dispute over sovereignty of part of Mauritian territory would not prevent Mauritius from adhering to the TPNW, however. Without effective control of the Chagos Islands, Mauritius is precluded from being able to implement the TPNW across those territories. If it were to secure full sovereignty over the Chagos Islands, Mauritius would need to seek the removal of any unlawful weapons and prohibit any unlawful activities by any states not party to the TPNW on that territory.
Recommendations
-
Mauritius should urgently adhere to the TPNW.
-
Mauritius should also adhere to the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
