Many countries have gone through a period when they used unconventional means to catch up, because they had nothing to lose. If US and allies punished China with tariffs in 1970s, it would have no effect because China just came out of being embargoed and having no export to speak of.

Now China is getting into the territory of having something to lose, between pressure from trade partners and internal forces, it'll eventually fall in line with other developed countries.

That being said, sino-phobia in US may or may not get better, depends on how US economy is doing, and if a new arch-enemy emerges to direct public anger at.
