Its obviously EU - so not the UK, or Norway or Switzerland or Russia...

I agree it is Eu-wide or pan-EU rather than pan European.

Its probably not going to solve the problems it sets out to given all the differences between EU countries legal systems, tax, regulation etc.

As the headline statements say “… EU-level …” rather than European, unless the smaller print explicitly mentions non-EU countries such as the UK I would assume that we aren't included.

It says "Pan-European" everywhere, but would this include Belarus?

No, but the UK already has easy company formation.

no :)
