Tito also sought to establish regional dominance over Yugoslavia's southern neighbours—Albania, Bulgaria, and Greece. The first overtures in this direction occurred in 1943, when a proposal for a regional headquarters to coordinate national Partisan actions fell through. Tito, who saw the Yugoslav component of the Partisans as superior, declined to go ahead with any scheme that would give other national components equal say. The pre-war partition of the contested region of Macedonia into three sections—Vardar, Pirin, and Aegean Macedonia—controlled by Yugoslavia, Bulgaria, and Greece respectively complicated regional relations. The presence of a substantial ethnic Albanian population in the Yugoslav region of Kosovo further impeded relations. In 1943, the Communist Party of Albania (, PKSH) proposed the transfer of Kosovo to Albania, only to be confronted with a counterproposal: incorporating Albania into the future Yugoslav federation. Tito and the PKSH first secretary, Enver Hoxha, revisited the idea in 1946, agreeing on the inevitability of the merger of the two countries.
