That would unfair to the 4CC participants (who use their placement at 4CC to build their ranking). Russia (while geographically transcontinental) is part of Europe for all intents and purposes - certainly in the eyes of figure skating.
Greenland (Denmark) is part of the North American continent and yet Danish skaters shouldn't be allowed to compete at 4CC.
Kazakhstan is, like Russia, transcontinental but Denis Ten isn't allowed to compete at Europeans along with 4CC.
And how many skaters are actually from what you would consider the "Asian" part of Russia? Technically/geographically, part of Canada (St. Pierre and Miquelon) belongs to and is governed by France - and it would be unfair to send Canadian skaters (none of whom hail from St. Pierre and Miquelon) to Europeans accordingly. :sarcasm:
And what next? Sending Russian skaters to compete in the Asian Games?
I can see why they're considering it (and it's good for more of the Russian field to get experience) but this is a bad idea that deliberately favours Russia and their current state of skating. Nobody brought up this transcontinental conversation a decade ago, but now it's being brought up because, inconveniently, the field is suddenly stacked.
