Yes and no... Colonisation as a whole - at least insofar as territorial expansion - is something every imperial power is guilty of and the Russian Empire very much so and hence, their control of everything from Germany to Canada in the 19th Century... Also explains why Russia continues to have let's say issues along their borders with the likes of Poland, Western Ukraine, the Caucasus etc. because of the ongoing bitterness from said expansionism
The Russian Empire also had limitations financially and logistically in the 19th Century and hence, for example, selling Alaska to the US for like $7 million
With regard to Africa, I do recall the Russian Empire having good relations with Ethiopia in relation to their fight against colonialism against Italy(?) and the fact that the majority of Ethiopians are Orthodox Christians probably endeared them to the Tsar
The USSR is a different story... They didn't see themselves as an empire in the traditional sense but rather the head of a movement, an ideology, to free people from imperialist exploitation and that had a particular draw in Africa... For example, Patrice Lumumba was the first PM of Congo who was assassinated with the connivance of the Belgians and CIA was lionised in the USSR
As for electoral interference, that is something else and all major powers do it --> see the abovementioned Mr Lumumba
