Re: "Iron Man 3" Review and Discussion Thread (spoilers)
I can't remember how much this has been discussed, but I think it's worth keeping in mind this was a Chinese co-production, so that probably made them pretty paranoid about making the true villain Chinese. Even if they didn't want to go the full comic book version, it probably made them pretty nervous making him Chinese at all.
