Its difficult to say what the impact will be. Details within the implementation phase of things can often resemble the opposite of what headlines say. There is division between what Trump supports and what other politicians in office support. There is likewise division between Xi Jinping and chinese leaders on how trade disputes should be handled. In some cases we find american politicians trying to undermine Trump's efforts. Although it is not as visible or public the same thing is likely happening in china.

There are many variables and they don't all align. People don't necessarily do what they say they will. We often see those in office consistently doing the opposite of their remarks and not following through on promises.

When circumstances look good for the united states and bad for china, the yuan seems to devalue. And the opposite appears to occur when the USA suffers some type of setback. We're far from knowing the end result imo.
