My impression from meeting in Mainland China with scholars is that that China does not see the economic warfare as a Trump policy, rather as a US state strategy.
Most analysts argue that Trump is in fact preferable because it was under Democrat Obama and Hillary that the US initiated a very militarist Rebalance policy and weponised the TPP.
The difference between Dems and Reps is only a difference of rhetoric. The content is the same.
It seems that the US regime found out that it became urgent to deal quickly with China, rather than playing the long game. Hence, Trump is doing things faster but, as a matter of fact, China is more comfortable with him than it would be, say, with Hillary.
That's why you cannot see a similar demonization of Trump in China unlike elsewhere in Europe or Middle East.
Hillary Clinton would've articulated a more sophisticated anti-China strategy. At the same time, she was a tool of the neoliberals so she would've kept trade relations the way they are now, and allowed American multinationals to continue profiting off of the American consumer while taking advantage of the low cost of manufacturing in China.
However, Trump's no 1 priority is to rebuild America's industrial base, and that's why China is a major target, because more than any other country, it threatens American industry and dominance. However, Trump's instincts do not allow him to cooperate with other countries to build a sophisticated anti-China strategy. He is hostile towards the European liberal elites, and sees Japan and South Korea as ripping off the American market like China is doing, and sees brown countries as shitholes flooding the US with inferior racial stock, so he's definitely not doing the US image any favors overseas.
