Maybe I can speak briefly and then give it to the experts on human rights here.
First of all, with regard to your first part, when I started to get into this work, my feeling was that it's like the song, “To know know know her/Is to love love love her”. If we had a dialogue and we explained to the Chinese our political institutions and our values, once they understood them, they would want them for themselves, because we've developed a wonderful country based on these values of universal human rights. It turns out that this is not actually the case. I've been waiting many years. I'm now fifty years old, and I'm wondering how many more years it will be before I see the Chinese decide to convert to a liberal democracy.
With regard to the exit question, I should point out that we are concerned about illegal migration from China to Canada, and part of our government activity has been to encourage the Chinese border police to enforce their laws about illegal exit from the country. There seems to be a tension between our desire to tell the Chinese that they shouldn't be allowing those people from Fujian to leave the country and get on boats to come to Canada—which is part of our interaction with the Chinese authorities—and the human right to freely travel if they so wish.
In terms of the issue of the shooting of those people, as a Canadian, I was simply appalled by what I saw. I feel there is absolutely no justification for the border police to resort to guns and to shoot down people who are simply trying to leave the country to go to Nepal for the purpose of religious education that is not available to them in China.
