Regrettably your history knowledge is very poor.  Ukraine was known under this name some 400 years before Russia was ever known as something other than the Duchy of Moscow . Before Moscow even existed on a map it was simply a territory, a land mass, ruled by Mongolian tribes, including  the same Genghis Khan that invaded central Europe. No European nation, as it is known today, existed in its present  borders at the time when Yaroslav the Wise ruled the powerful Kyivan  State.
