After the war, the USSR and Yugoslavia signed a friendship treaty when Tito met with Stalin in Moscow in 1945. They established good bilateral relations which Yugoslav domestic and foreign policies did not appear to seriously affect. Although the KPJ pursued the goal of a communist or socialist society in a way that sometimes differed from the Soviet model, the differences were only in method, not in objective. In 1945, Yugoslavia relied on United Nations Relief and Rehabilitation Administration aid as it experienced food shortages, but it gave much greater internal publicity to comparably smaller Soviet assistance. Nonetheless, in 1945, Stalin complained that Yugoslavia's foreign policy was unreasonable because of its territorial claims against most of its neighbours. (Yugoslavia had made claims against Hungary, Austria, and the Free Territory of Trieste, which had been carved out of pre-war Italian territory.) Tito then gave a speech criticising the USSR, alleging inadequate Soviet backing of his territorial demands. The confrontation with the Western Allies became tense in August 1946 when Yugoslav fighters forced a United States Army Air Forces Douglas C-47 Skytrain to crash-land near Ljubljana and shot down another above Bled, capturing ten and killing a crew of five in a space of ten days. The Western Allies incorrectly believed that Stalin encouraged Tito's persistence; Stalin actually wished to avoid confrontation with the West over the issue.
