Check the Pokemon in Japan, along with all the toys from Japanese anime. Heck the one area in Japan set aside that is not selling crap is full of pictures of animated characters....
I though I saw Donald in Mexico, must have been some other duck...
Those lines in WS in the pavilions, they are to do M&G with "toons", that is what the guests want it seems. Toons all over WS everyday, is Olaf going to tip the balance somehow in your view?
And the plastic fake viking horns and swords in Norway you can buy right now, made in China.
A lot of the stuff sold in Japan, made in China. I know a lot of the toys are, and they sell a ton of toys in Japan.
The shirt I bought my son in Mexico last june, made in Indonesia. Like I posted earlier, it say "I Taco Mexico" with the word Taco being replaced with a picture of a taco. Hardly a cultural piece of Mexican art. Nor were the shot glasses they were selling for that matter.
Lots of example like this all over WS.
Certainly are items made in countries they represent, I bought a nice German made bell in June as well. But trying to say the shops are full of items made in the pavilion country is not the facts and thus not consistent with Epcot's theme under your example.
