I was going to make some of the same points that Sophie made.
I would add that, given this backdrop of concern about China's unwillingness to recognize dual nationality—and of course we've seen it in Huseyin Celil's case now for 14 years—I think, if you add to that an overlay of arbitrariness, the very real concern is that it may well be the dual nationals who are at the greatest risk, who are the ones least likely to have their Canadian citizenship recognized. There may be others, around whom there's not a lot of political or other interest, who would be able to leave fairly smoothly.
There's going to need to be a very sophisticated and multi-layered and multilateral—there's that word again—strategy here.
