Yes, I'd like to say something.
Sanctions are a symbol and, even if largely ineffectual, they do symbolize our detestation for what is taking place. We live by symbols, but of course they can backfire, and they're not very effective because we know who runs China. It isn't Carrie Lam and other people that these sanctions have been placed against. Can we sanction Xi Jinping? It would be good because the financial sanctions on Hong Kong would affect the fortunes of many people in his family, and the fortunes of the families of other members of the Chinese Politburo. However, Xi Jinping is the boss. There's one-man management in China. Sanctions should be imposed upon him, but they can't be. It's not politically feasible, so it shows the limitations of sanctions.
There are other steps that can be taken. Canada, the U.S., the U.K. and other democratic countries can welcome immigration to a greater extent than they have done so far for the people of Hong Kong, and provide them with the financial wherewithal to make that welcome realistic. Now, most of them won't want to come, and they may want to go to different places; but that's a real symbol, and it doesn't harm the people of Hong Kong.
Anything we do can be mobilized by the propaganda apparatus in Beijing to foment greater nationalism in China. There's nothing we can do about that. That's what dictatorships do. We have to be as rational as we can. I think the foremost symbolic and effective measure we can take is to foster the possibility of immigration if people want to leave. I don't blame them if they don't want to leave. I admire those who will fight to the end. Many will decide, “Look, it's not so bad.” People in China have given up their freedoms, but they have a good life in many places.
