Addressing participants of the Ambassadors conference in Belgrade on Tuesday, Tadic said that "Serbia is always able to mediate in resolving the issues that plague Macedonia".
"We are ready to mediate in the solution of the dispute between Greece and Macedonia. We want to be part of the solution, and not part of the problem as was the case in the past," he said.
Athens and Skopje have been locked in a dispute over Macedonia's name, that has so far blocked Macedonia's entry into NATO and progress in EU accession. Greece argues that Macedonia's constitutional name of Republic of Macedonia implies territorial ambitions over its northern province, also called Macedonia.
Tadic also said Belgrade wants to settle the long running dispute between the Serbian and Macedonian Orthodox churches.
Ever since Macedonia gained independence in 1991, its name has been the subject of a bitter dispute with southern neighbor, Greece.
The longstanding mediator between Athens and Skopje, Matthew Nimetz, rarely reveals his feelings – but admits regret that the name ‘New Macedonia’ didn’t stick.
Placing the statue of Alexander the Great in the centre of Skopje is an unintentional allegory for the end of transition in Macedonia.
The continued blockade of Macedonia’s NATO hopes - which we’re seeing once again at the Chicago summit - shows the West still prefers the principle of solidarity to obedience to international law.
