 In retirement , Molotov remained totally unrepentant about his role during Stalin 's rule . He suffered a heart attack in January 1962 . After the Sino @-@ Soviet split , it was reported that he agreed with the criticisms made by Mao Zedong of the supposed " revisionism " of Khrushchev 's policies . According to Roy Medvedev , Stalin 's daughter Svetlana recalled Molotov 's wife telling her : " Your father was a genius . There 's no revolutionary spirit around nowadays , just opportunism everywhere " and " China 's our only hope . Only they have kept alive the revolutionary spirit " .
