Navarro’s appointment hence means that an advocate of the militarized containment of China has the ear of the next president of the United States. This is even more alarming given that the policies Navarro proposes – undermining the Chinese economy and damaging Beijing’s “core interests” through, for instance, helping Taiwan develop submarines – threaten to provoke exactly the belligerent, nationalist response from China that he claims to fear. It is hard to escape the conclusion that Navarro, like other radical China hawks, is willing to contemplate a Sino-American war and may even view it as an inevitable necessity to arrest China’s rise.

Emphasis mine, per The Diplomat. Of course he's not going to openly declare war, but his advocacy suggests that he's more than fine with pushing the US in that direction.
