Accession of Macedonia to NATO
Following an agreement in June 2018 to rename the country the Republic of North Macedonia, NATO agreed to consider extending an invitation to the country to join at its summit on 11–12 July. On 11 July 2018, NATO invited Macedonia to begin membership talks, saying the country could join the organization once the naming issue was resolved. Formal accession talks began on 18 October 2018. Greece is expected to be the first NATO member state to ratify Macedonia’s NATO accession protocol.
