Finland or Poland are directly connected to Russia or the Ukraine. And there aren't regular border controls within the "European Union Customs Union" https://en.wikipedia.org/wiki/European_Union_Customs_Union |
That wasn't my point. Borders are much more than their controls. They represent geo-political distinctions. People within borders interact more with others within their borders than outside due to aligned political and cultural similarities (albeit there are exceptions when the politics don't coincide with culture.) I'm sure there is much more interaction between Los Angeles and New York City than Kiev and London.
