Also, I think you'll find that it's pretty well documented publicly that China has made it very clear that it is looking abroad for those people who have been involved in illegal activity.

There's been a lot of controversy over whether these persons are really criminal offenders or are at odds with the political establishment.
Those comments are made in that context, involving those individuals and the criminality that they're alleged to have committed in China.
