I don't want to say that the revenue stream is really the significant thing. If you were stopping organ tourism coming from Canada, perhaps that's not the most salient point. But it is true that there are cases, at least unverified, of people having paid up to $2 million for one of these organs. If you're talking about some extremely wealthy person, the kind of person who could easily exist in Japan, Canada, or the United States, it's very possible that some people have paid these sorts of figures. That is an incentive.
It is true that the Chinese pay half the foreigner price. They pay sometimes much less than the foreigner price. For example, if we take the $62,000 U.S. wanted for a kidney back in 2004, the Chinese were paying sometimes as low as $2,000 for that same kidney, so there is a monetary point.
But I think the larger point is this, that China has great ambitions in the medical field. They see this as what they call a pillar industry—pharmaceuticals. They see themselves as the new Rome, the new FDA, where people will go to do their experiments and go for drug approval. Any message that this body can send them saying, “No, you're not there yet” is very important. It does have a massive impact, far beyond what you might recognize.
