I don't think their treaty will amount to much.
All of these things will still make it into these countries if their consumers want it, and they do.
Just more stupid nanny state controls that will fail.
Hollywood will get around whatever restrictions are put into place. They can offshore a certain % of production to Canada or Mexico and turn the movie into a "foreign" product for purposes of the agreement. I'm sure there's no shortage of people within the UN that they can buy off if needed.
