How Many Nations Follow the FAA?

In the US we have a set of aviation regulations all made up by the FAA.

In Canada they have a different set of rules all made up by Transport
Canada. They don't blindly follow the American FAA system.

When in Belize I walked through the capital to the general aviation airport
and talked to a pilot. It turns out that Belize uses the FAA regulations.
Pilots in Belize actually refer to "Part 91" which is amazing since that's a
rule made by the American government and the Belize government just tells
they "Do everything you would have to if you were in America".

I also notice that the South African set of rules for general aviation is
called "part 91".

So, how many nations don't make their own aviation rule but instead simply
require the locals to follow the American FAA rules?

And as a follow-up, do any non-European nations require one to follow the
European rules?
