I believe GP's intent was to point out that a company can get into an agreement with a government (make an offer they can't refuse), but a company cannot get a "region" to sign an agreement/contract with them.

Regional governments exist: https://en.wikipedia.org/wiki/Politics_of_Sicily

Yes the continents too

What region is UK?

That whole thread is absurd, but if I would have to answer I would say Great Britain is the name of the region/group of islands? Open to be wrong, I know little about the UK

Great Britain is the big island.

UK (United Kingdom of Great Britain and Northern Ireland) is a country consisting of several countries and other territories.
