Good or bad for China? Hard to say. This is a gamble. With great power comes great responsibility. My opinion:
1. If the next government succeeds in any 1 of the following, it counts as a huge win and nothing else matters: cancelling petrodollar, flipping Japan, taking Taiwan, outright defeat (military or political) of some certain country, digital RMB as top reserve currency
2. If the next government succeeds in any 3 of the following, it counts as a neutral: domestic EUV, domestic widebody civil aviation, BRI success, total energy independence, Russian victory in Ukraine, nominal GDP exceeding US, COVID hitting everyone
3. If the next government doesn't succeed at any of the above, it is bad, because it causes political instability due to centralizing too much power and doing nothing with it. Successive governments will struggle to claim similar legitimacy as Xi's as he's broken too many precedents and is basically wasting an asset with Hu Chunhua.
I think xi is trying to finish taiwan problem and I'm not sure how many of party people support something like common prosperity/ rural revitalization Instead previous leaders focused more on GDP & export but xi wants more self sufficient economy as well as wants to increase more middle class so that it can turn china into bigger consumer mar for internal cycle ( you have heard of dual circulation) so that you won't be dependent on export kind of like American economy and I'm sure many Shanghai guys want to rely more on export based economy .
I think few goals which xi wants to achieve.
1. De dollarisation ( BRICS / yuan internationalization) , export to USA Europe helps dollar stay number 1, less export oriented economy means west will starve to get Chinese product which can also protect china from external problem & inflation.
2. Taiwan problem ( just they did changes in constitution about this issue)
3. More border control & scs control.
4. Transforming PLA to number 1 ( fight with anybody who is interfering directly in China's territory)
5. More self sufficient economy ( made in china will go through full effort)
If china achieve all this under xi then china will enter into new era where USA dominance will be gone , USA will explode with debt & collapse.
But if you think and look back then under xi China became more self reliant, more innovative, more clean & PLA Also became near peer to USA military . I think xi didn't liked few things about how much hew was pushing for self reliant & made in china 2025 goal but still companies & government organisations was still buying foreign techs . There is a reason why west & even big neighbours hates xi more than CCP.
1. Technology self-sufficiency in critical sectors for technological security.
2. Accelerate military build up including expanding nuclear arsenal for national security.
3. Boost domestic consumption for economic security.
4. Expand domestic capital market financing for financial security.
4. Digital yuan use expanded to all of China for financial security.
5. Deflating property sector
6. Boosting birth rates.
I would say Taiwan is one of China's minor problems right now. Folks, China is choosing the whip they are going to use against Taiwan.Two, there will be a clean-the-house process in the financial industry, where it has been the weakest link in China economical eco-system since Zhu Rong Ji retired. Along the same line, there will be more efforts in promoting RMB for international settlement.
Three, on international front, there will be more RCEP, SCO and BRICS. The longer this war continues, the more important those regional organizations become. If and when Iran joins SCO and Saudi joins BRICS, that would mark the beginning of an era in which the world would be officially divided in the east vs the west.
The biggest problems I see that need a total or partial solution in the short term, technological independence, fixing the inflated real estate sector, the financial system, maintaining economic growth above 4.5%-5% and intensifying the birth rate, if necessary, even encouraging immigration.
I think it is very likely that the other things will intensify, but not to the point of causing a rupture as you say, I see the dollar becoming less important in international trade in the long term, as well as the RMB having a greater participation in the international market as a reserve currency, in addition to the other things already mentioned. This will not be difficult to achieve now with the consolidation of power around Xi, but it will depend on the external scenario as well and how China will behave in this scenario, it may be that it seeks some other foreign policy that is more divergent with the US and the West in general, or maybe not, this is still too early to say, but any of the items you mentioned depend directly or indirectly on the outside scenario.
The direction of Xi's trade policy prioritizing internal development rather than encouraging exports just for the sake of exporting will give a huge boost to the purchasing power of the Chinese population, if this is one of Xi's central goals for the next 5 years, I would blindly the support. Furthermore, this has a double effect, the West will now no longer be able to import cheap goods, this increases the inflationary cost for the West, while reducing it for the Chinese, but care has to be taken with this policy because it affects critical sectors of the Chinese economy. like shipbuilding that China is the world leader, I would say the change will be gradual and perhaps even slow, even as Xi consolidates power.
Basically all of the above has consequences for the rest of the other claimed priority objectives. This is going to be interesting.
