After 1950 Greece insisted that as far as it was concerned a Macedonian problem did not exist, since its sovereignty in Greek-Macedonia, recognised by international treaties, had also been confirmed by the outcome of the Second World War. At that time, the Macedonian Question mainly concerned the dispute between Sofia and Belgrade over the Yugoslav south and the Bulgarian region of Pirin.

Greece and Yugoslavia maintained friendly relations, and participated, together with Turkey, in the Balkan Pacts of 1953-54. Even so, there was friction between Athens and Belgrade whenever Skopje tried to raise issues about a "Macedonian" minority in Greece or to put forward claims on Greece.
The "golden age" of Greek-Yugoslav relations (1954-60) coincides with the period in which Yugoslav federal officials did not make provocative statements about northern Greece. In contrast, as soon as the Yugoslavs violated this principle in 1961, a serious crisis in bilateral relations ensued. However, as long as Tito was alive, Belgrade managed to keep Skopje on the line of moderation.
