On October 28, 1920, France, Britain, Italy and Japan signed the Treaty of Paris, which recognized Bessarabia’s union with Romania. This treaty was ratified by the UK, France and Italy, but not by Japan. The Soviet Union didn’t recognize the union of Bessarabia with Romania and, following the ultimatum of 26 and 27/28 June 1940, occupied Bessarabia, Northern Bukovina and Hertza region. Peace Treaty of February 10, 1947 signed by Romania, on the one hand, and the Allied and Associated Powers, on the other hand, renewed in a slightly modified form the text of the Armistice Convention of 12 September 1944. The Treaty provided for the setting of Soviet- Romanian border in accordance with the so couled Soviet-Romanian Agreement of 28 June 1940. Thus, the Great Western democracies acknowledged through official documents the agreement between Hitler and Stalin, materialized in Molotov-Ribbentrop Pact of August 23, 1939 and the Soviet ultimatum of June 1940. Thereupon, Bessarabia and Northern Bukovina remained under Soviet occupation.
