>"Xi’s ideological beliefs have committed China to the goal of building what Xi describes as a “fairer and more just” international system—one anchored in Chinese power rather than American power"
>"Xi has communicated to the party a crystal-clear message: China is much more powerful than it ever was, and he intends to use this power to change the course of history."
This being in the underlying goal (or as your put it - inevitability) of China being the predominant power in Asia.
>"But Xi is not completely secure. His Achilles’ heel is the economy"
And this comment reflecting the idea that he can only accomplish all this with a strong economy. And with the string of bad news coming out of China lately, one can't help but noticed Xi's much more conciliatory tone in the past few months compared with the image of a couple years back.
