I am Ukrainian and I can confirm, we do not exist.

Doesn't Ukraine also mean "borderland?"

It's actually funny which name for countries ends up getting borrowed. The Finnish word for Finland is Suomi. The Swedish word for Finland is Finland. Ironically, the Swedish word for Sweden is Sverige, but at least you can see the Sw/Sv commonality.

"krai" also means area, territory, not just border. The meaning "borderland" is a Russian derogatory narrative, very hypocritical btw.
