I think there were probably two categories, and as I said, we were not always absolutely certain about this. There was a fog of uncertainty, and we also had information from security agencies who had views as well. One thing we certainly would not approve of at all is if there were individuals coming on behalf of Chinese security agencies to pressure family members to return to China or threatening their families, things of that nature. I know there had been cases of that and that was one thing we would strongly oppose.
A second area, as you indicated, would be people who wanted to try to exert inappropriate influence on the Chinese diaspora. Again, we didn't always know for sure what everybody was up to, but when the weight of suspicion was sufficient, we would deny a visa. I can't say what the proportion was, but I remember it being a pretty substantial number.
