The ideological steps undertaken were made clear by the ousting of the "Sov-Rom" companies, together with the toning down of Soviet-Romanian common cultural ventures. In 1958 the Red Army withdrew its last troops from Romania (a personal achievement of Gheorghiu-Dej). The official "History of Romania" made then reference to a Romanian Bessarabia, as well as other topics which tensed relations between the two communist countries. Moreover, the final years of Dej's regime saw the publishing of Karl Marx texts, which had previously been kept secret, dealing with Russia's imperial policy in previously Romanian regions that were still part of the Soviet Union.
