"How would we have the ability to do that?"
Hmm, maybe go to your communist government and tell them that a fantastic gymnast isn't old enough to compete in the Olympics. The government changes the passports to show that an athlete is older than they are, then China can win the Gold medal in their home nation.
It stinks. But I guess if the FIG and IOC aren't going to do anything about it, there's nothing anyone else can do, either.
Thanks for posting this, by the way.
