Prime Minister Nikola Gruevski of the Former Yugoslav Republic of Macedonia (FYROM) has accused Greece of undermining efforts to find a solution to the two-decade name dispute between the two countries.

“Our southern neighbor continues to believe that the name issue can be solved by [using] obstacles, blackmail and insults,” said Gruevski during a VMRO-DPMNE party meeting on Thursday, accusing Athens of using the acronym FYROM instead of the Balkan country’s full name.

“It is as if we start calling them FOPOG – Former Ottoman Province of Greece,” he said. “How offended would they then feel?”
