On May 21, 2024, the Republic of Nauru became the 159th State with which the Principality of Monaco has established diplomatic relations, following the signing of joint communiqués by the Permanent Representatives to the United Nations in New York, H.E. Ms. Margo Deiye and H.E. Ms. Isabelle Picco. The Republic of Nauru, the smallest republic in the world, is an island nation in Oceania and has been a member of the United Nations since 1999. Close to the equator, it is among the countries particularly affected by the impacts of climate change, especially heatwaves and rising sea levels. The Permanent Representatives discussed several topics of common interest, particularly the conservation and sustainable use of the oceans and the sharing of benefits for developing countries under the High Seas Agreement.
