I understand now.
I think in America we have a pretty simplified view of China (shocker) as this massive, powerful force that can do anything it wants with a centralized party-state. This book does a good job of detailing the internal problems that China faces in the coming years. Believe it or not, but China does face internal gridlock like America does, albeit with a uniquely different character. American gridlock looks "horizontal" between institutions that serve as checks on each other, where China's gridlock is "vertical". The central committee cannot command immediate and widespread control of the country when there are difference of opinions among regional party orgs and the top figures. A lot of this is demonstrated by the frought negotiations surrounding the construction of the Three Gorges Dam (google it) and I think a current case in point is zero-covid restrictions across the current regions. The common pattern most scholars seem to identify is when problems begin to be coordinated BETWEEN provinces that the party will respond to pushback. I think some key things I pulled out of this reading is the diversity of economy that China has to manage (private enterprise, state-owned enterprise, rural land-sharing, joint state-private business, etc) and the resource challenge that they are in for (almost a reverse of the US, net wheat importer, net manufactured goods exporter, 30% arable land compared to the US's 70%).
Anyway, good luck with all that, sure it'll turn out okay
