Technically, legally, diplomatically and politically, the Russian Federation is a European Country. I personally don't think it is, but someone at some point in time decided that it was. Probably something to do with it's capital city/industrial centre/ population centre being in the European side.
And Europe and Asia are separate continents, as anyone who has ever studied geography should know. Stop joining them, since Africa is also joined to "Eurasia" so shouldn't that be part of this Uber-Continent too? Its the same logic, and its fallible.
I'm no where near an expert on this sort of thing, but this is what I make out of this.
