Kosygin protected János Kádár's economic reforms and his position as leader of the Hungarian People's Republic from intervention by the Soviet leadership. Polish leader Władysław Gomułka, who was removed from all of his posts in 1970, was succeeded by Edward Gierek who tried to revitalize the economy of the People's Republic of Poland by borrowing money from the First World. The Soviet leadership approved both countries' respective economic experiments, since it was trying to reduce its large Eastern Bloc subsidy programme in the form of cheap oil and gas exports. During the discussions within the Soviet leadership of a possible Soviet invasion of Czechoslovakia Kosygin reminded leaders of the consequences of the Soviet suppression of the 1956 Hungarian revolution. Kosygin's stance became more aggressive later on when he understood that the reforms in Czechoslovakia could be turned against his 1965 Soviet economic reform.
