On 21 May 2024, the Principality of Monaco established diplomatic relations with the Republic of Nauru, which becomes the 159th State to have formal ties with Monaco. The agreement was sealed with the signatures of Margo Deiye, Permanent Representative of Nauru and Isabelle Picco, Permanent Representative of Monaco.


The world’s smallest republic, Nauru is an island state in Oceania and a member of the United Nations since 1999. Lying close to the equator, it ranks among the countries that are particularly affected by the impacts of climate change, particularly heat waves and rising sea levels.
