It's debatable, but from your reference it seems like the opposite:

It has been argued[by whom?] that without the Mongol destruction of Kievan Rus', the Tsardom of Russia and subsequently the Russian Empire would not have risen. Trade routes with the East came through the Rus' lands, making them a center for trade from both worlds. Mongol influence, while destructive to their enemies, had a significant long term effect on the rise of modern Russia, Ukraine, and Belarus.
