After the Treaty of Vis or the Tito–Šubašić Agreement, Tito and Šubašić met in Vršac on 20 October 1944. Tito's stay in the Soviet Union during the Moscow Conference between Joseph Stalin and Winston Churchill opened the door for other agreements between representatives of the National Committee and the Royal Government. The agreement was concluded on 1 November 1944 in Belgrade and is known as the Belgrade Agreement.
