> What does this mean for Xi's leadership and the CCP?
Few days of bad mood
> Will this threaten their power?
Who will threaten his power? Han Zheng is the last Jiang loyalist in party's higher tiers, he is under extreme pressure for his handling of HK now.
I bet Xi will come out of that even more powerful, by dumping blame on whomever may oppose him.
> Does this cement the US as the leading economy for the next quarter century?
Leading economy != leading country. The negative feedback on currency will just roll Chinese companies back few years in their market outlook. Companies that were previously aiming for selling to developed economies will thing of places like South Asia, Africa, Eastern Europe and such.
> What does this mean for up and coming rivals, such as India and Vietnam?
Not much for India. India just like Russia doesn't really want joining the global economy, and the impediment comes from within.
For Vietnam... good times to come. And for whomever will be working as fixers, bringing Western companies there.
But there is a big BUT. The moment Vietnam will get up on the economic ladder, there is a certain chance US or somebody else will try to pull the same tariff hike on them.
> How will this effect China's middle class?
Chinese middle class largely works in service sector, and that depends near solely on internal demand.
> Will we see an increase in Chinese expats?
Sure, there is always a knee jerk reaction among Chinese rich to any new wave of doomsayers.
When I was living in Vancouver I met quite a few rich Chinese. One of whom was an owner of the 4th largest scrap metal company in China. He sold his business at an insane 60% discount, and ran to Canada the moment he read "Chinese steel bubble is about to pop" in an "esteemed Western publication" in 2010.
The last time I checked on him, he was still living a nice rentier life with 3 houses in Vancouver, but was super cringy about him selling so low, and trusting random rags for making a once in a lifetime decision.
Near same was the case with 3 factory owners. Two had electronic factories, and one did clothing. You can still argue about one with clothing business making a correct decision closing the shop, but for two electronics factory owner, the decision to close their businesses made zero sense.
I asked them separately why they exchanged life in Canada for untold millions to come. None was able to give an answer, saying simply they don't understand their own rationale back then.
To them, people of peasant background, life in the West looked as something near mythical. They grew up thinking that "getting to the West" was something like a once in a lifetime chance, something what exceeds just anything on the list of ones personal achievements. To such people, parting with a few million buck a year business for a house in Vancouver and steady life genuinely looks like a good deal.
The new generation of entrepreneurs of course don't hold the West in such esteem, and some actually thing of it with some degree of contempt.
