's Special Envoy to mediate the resolution of the Macedonian Issue, an important regional dispute that the United Nations Security Council had acted upon, involving both a national name and related disputes.
The United Nations mediator of this dispute was Cyrus Vance, former US Secretary of State, and Nimetz worked with Vance to assist the parties to reach agreement on a number of important points, which culminated in the signing of the Interim Agreement of September 13, 1995, by Greece and its northern neighbor, now officially known as the
Republic of North Macedonia
North Macedonia, officially the Republic of North Macedonia, is a landlocked country in Southeast Europe. It shares land borders with Greece to the south, Albania to the west, Bulgaria to the east, Kosovo to the northwest and Serbia to the n ...
(but at that time admitted to the United Nations under the temporary designation "The Former Yugoslav Republic of Macedonia"), at the United Nations which resolved many of the issues between the two countries. Nimetz has written about the dispute in an article "The Macedonian "Name" Dispute: The Macedonian Question—Resolved?" in Nationalities Papers, Vol. 48, March 2020.
The major issues between the two neighbors were not, however, resolved in the Interim Agreement, and in 1999, Nimetz was appointed to succeed Cyrus Vance as the personal envoy of the UN secretary-general regarding the naming dispute.

BBC News (August 2, 2017). Nimetz has continued to work mediating between Greece and the Republic of North Macedonia, for more than two decades. He worked for a nominal salary of US$1 a year in order to find a solution suitable for all concerned.
Nimetz believed that the long-running issue was capable of resolution and made a number of proposals to the two parties during the course of his mediation efforts to bring them closer to a solution. During intense efforts commencing with his proposal of January 11, 2018, the parties hammered out an agreement, negotiated primarily by the two foreign ministers, Nikola Dimitrov for North Macedonia and Nikos Kotzias of Greece, and ultimately by the two prime ministers Alexis Tsipras of Greece and Zoran Zaev of North Macedonia, with the intensive mediation support of Nimetz and his UN team. Support was provided by the European Commission and friendly states such as the United States and various members of the European Union. On June 17, 2018 an agreement to resolve the dispute with the adoption of the name "Republic of North Macedonia" was signed in at Lake Prespes (also known as Lake Prespa) on the border of the two states. After difficult processes in both countries the agreement was ratified by the parliaments of both states and came into effect in early 2019, with the change of the name of the state to Republic of North Macedonia and other actions taken to fulfill the Prespa Agreement. Following the successful resolution of the "name" dispute, Nimetz resigned in 2019 as the Personal Envoy of the Secretary-General of the United Nations. It is said that his UN mediation effort on the "name" dispute from 1999-2019 was the longest continuous mediation of one dispute by a UN mediator.
