A major obstacle for the accession process was the Republic's unresolved objection by Greece over its name, as Greece argued that it implied territorial ambitions towards Greece's own northern province of Macedonia. While the country preferred to be called by its constitutional name, Republic of Macedonia, the European Union, in acknowledgment of concerns raised by Greece, maintained a practice of recognising it only as the "former Yugoslav Republic of Macedonia", a compromise of "provisional reference" introduced by the United Nations in 1993. Greece, as any other EU country, has veto power against new accessions, and blocked Macedonian accession due to the naming dispute.[8][9][10][11]
