There is plenty for Xi Jinping to like in the NSS. Trump explicitly disclaims any desire to hector authoritarian states on human rights; his interventions will only take place in Europe. He believes in power, not rules, and gives a green light to large nations to work their will. And he advocates for a Trump corollary to the Monroe Doctrine, which practically invites China to do the same and invade Taiwan.
The NSS does support protecting Taiwan, to be sure, but based solely on American economic interests, not the security of our allies. The document demands that the Asian allies beef up their defense spending while offering nothing but tariffs in return. Any notion of solidarity on the basis of liberal democratic values is, of course, completely off the table.
Trump makes it completely clear that he views China primarily as an economic threat to the United States, not an ideological or military adversary. His principal objective is to reduce the Chinese trade surplus. That could be done by signing agreements with our Asian allies that bind them more closely to America, but Trump has done precisely the opposite with his trade policies. As a result, regardless of the suggestions that the objective is to enhance the Biden approach of flexible containment, it is hard to read the NSS, in the real world, as anything but the beginning of a spheres of influence doctrine.
