China's recent obsession with arresting Canadians is easier to understand and predict if it is seen as an attempt to alienate US allies from the US. Based on this, we can expect mistreatment of other US citizen allies in the future. They did something similar with an Australian back in January. By lashing out at citizens of US allies, China—more than likely—hopes to make those countries regret being friends with the US...
...because that works in Chinese culture's inside baseball.
Something about Chinese-Confucian culture is obsessed with "the group" and "uniform conformity". When someone steps "out of line"—whatever the groupthink happens to have decided "the line" is this afternoon—others within that culture instinctively begin to attack that person like hyenas attack an isolated impala in the wild. It's almost as if they are governed by a hypnotic auto-think. Small charges, snaps, and bites slowly creep in from any and every side until the group kills and devours whoever tried to be different.
This is exactly what China has done to Taiwan's allies. Most of them caved. Senator Rubio lashed out at El Salvador for abandoning Taiwan last August when the trend became annoyingly obvious. Since it worked with them, maybe China thinks it will work with the English-speaking world.
But, the Chinese only learn "Chinglish" at best, whether with language or with culture. There attempt will only backfire and that will explain the members of the coming alliance that defeats China in the fast-approaching scuffle. And, it will explain the coming alliance that nations just east of China will soon deepen with the English-speaking world, as well as the growing alienation between English-America and Latin-America. But, that won't be seen for another decade.
