I would say that’s an extension of the idea that rich people run the US government, which runs global organizations such as the world bank, which runs these ISDS courts.
China is just big enough to be able to ignore these global orgs.
Now try to win a case against the interests or connections of a high ranking official in China.
"Law and order" is not equal to "the rule of law". Both China and the US ascribe to the idea of "might makes right", which is in essence an organized form of lawless state. It is conceptually the same as in criminal gangs, only with vastly better optics. That is why anyone not in power should strive for a rules-based order, for their own best interest at least.
China is an authoritarian regime. The US is a kleptocracy flirting with autocracy.
Neither place the rights of their citizens in much regard, though money definitely helps in both places.
The possible outcomes for individuals in China though are Orwellian.
