You're right about that. Big 5th Column in the West. China has the largest diaspora in the world out of any country. Obviously not all of them are loyal to China, I have many Chinese friends who don't like that gov, but many are loyal, and many don't have a choice but to be loyal. Look at all the Chinese-Canadians who protested in defence of China when the whole Hong Kong protests happened months ago.
If you refuse to spy on Canada for the China gov, they threaten to make your family in China disappear. If you tweet things critical of China they visit your family in China. We have entire cities in Canada dominated by Chinese-Canadians, are they all loyal to this country? We have an entire province becoming Chinese, are they all loyal? Canada doesn't demand much loyalty. It's a post-national state our PM says.
