Council to grant a mandate for the Mosul region to Britain without their consent. Atatürk countered by concluding a non-aggression pact with the USSR on 17 December. In 1935, the pact was prolonged for another 10 years. In 1933, the Soviet Defence Minister Kliment Voroshilov visited Turkey and attended the tenth year celebrations of the Republic. Atatürk explained his position regarding the realization of his plan for a Balkan Federation economically uniting Turkey, Greece, Romania, Yugoslavia and Bulgaria. During the second half of the 1930s, Atatürk tried to establish a closer relationship with Britain and other major Western powers, which caused displeasure on the part of the Soviets.

Indeed, Venizelos' successor Panagis Tsaldaris came to visit Atatürk in September 1933 and signed a more comprehensive agreement called the Entente Cordiale between Greece and Turkey, which was a stepping stone for the Balkan Pact. Greek Premier Ioannis Metaxas once stated, with regard to Atatürk, that "...Greece, which has the highest estimation of the renowned leader, heroic soldier, and enlightened creator of Turkey.
