 The Prespa agreement, which replaces the Interim Accord of 1995, was signed on 17 June 2018 in a high-level ceremony at the Greek border village of Psarades on Lake Prespa, by the two foreign ministers Nikola Dimitrov and Nikos Kotzias and in the presence of the respective Prime Ministers, Zoran Zaev and Alexis Tsipras.The meeting was attended by the UN's Special Representative Matthew Nimetz, the Under-Secretary-General for Political Affairs Rosemary DiCarlo, the EU's High Representative of the Union for Foreign Affairs and Security Policy Federica Mogherini, and the European Commissioner for Enlargement and European Neighbourhood Policy Johannes Hahn, among others.After the ceremony, the prime ministers crossed over the border to the Macedonian side of Lake Prespa for lunch at the village of Oteševo, in a highly symbolic move that marked the first time a Greek Prime Minister ever entered the neighboring country since it declared independence in 1991.
