It's similar to how people say "Europe does this or that". Basically the part of their thoughts dedicated to that part of the world is so small that all they can afford is a tiny box, and everything has to go in there, reality be damned.

They may both decide to copy, or imitate laws similar to the ones the the EU has, but they can't 'ratify' them.
