Problem is nobody knows the future. XI didn't come into power until 2012 - until then China was moving slowly in the right direction (that is more open and free), so moves of those things there there seemed to encourage that. However XI has consolidated power and put a break on moving in the right direction and now we need to react.
I have no idea who will move what way in the future so I can only guess what we will regret in 10 years. However I must act on the world as I know it lest things get worse. (what makes things worse is open for debate)
I think that an open and free China would still have many of the same geopolitical incentives that authoritarian China does. It would still prefer to dominate global manufacturing, use its resources and manufacturing capabilities for geopolitical leverage, and militarily dominate the seas and islands in its vicinity. It would still be nationalist. It would still want to reverse the "century of humiliation".
Type of government does have an effect on economic and military policy, but being a liberal democracy does not make automatically make a country less interested in pursuing naked self-interest.
>...put a break on moving in the right direction and now we need to react
- What do you mean "the right direction"? Do you mean the "open and free direction" that "Hey you can't have our Nvidia chips but must keep selling us cheap rare earth"? - And who are "we"? I suggest "we"'d better take care of "ourselves" instead of "react".
I don't think its Xi's doing vs Globalist looking only for signals which confirmed their views and ignored or outrightly rejected everything contrary.
The rare-earth export restrictions have little if anything to do with Xi or with whether China evolves towards more freedom or more autocracy.
The export restrictions were not initiated by China, but they were an extremely moderate response to the US "sanctions" that blocked the sales to China of modern semiconductor manufacturing equipment, in order to eliminate the competition and to increase the prices in the DRAM and SSDs markets.
These US "sanctions", which were intended to preserve the monopoly of Micron et al., were the precondition that allowed the huge increase in the prices of memory products when the AI companies grabbed a large part of the production.
In my opinion, China has chosen extreme restraint in their response to the "sanctions" initiated by USA, presumably because they think that they would lose too much if cutting all the commerce with USA.
For me, I would have considered an unacceptable insult when another country declares that they want my country to remain a country that is technologically inferior and they would do anything to achieve this, notwithstanding anything of what they may have said and promised in the past. I certainly would not have wanted any further relations with such a country.
