In November 1989, at the XIVth and last congress of the PCR, Ceaușescu condemned the Molotov–Ribbentrop Pact and asked for the annulment of its consequences. In effect, this amounted to a demand for the return of Bessarabia (most of which was then a Soviet republic and since 1991 has been independent Moldova) and northern Bukovina, both of which had been occupied by the Soviet Union in 1940 and again at the end of World War II.
