I see the tide as being more about two egos splashing in a pool.
Yes, the US economy is very unstable, but the Chinese and American economies are intertwined and interdependent. The current conflict in a not a zero-sum cads game - both will lose. Trump is a petulant child, but the Chinese are driven by a need to be seen as stronger and smarter (face is very important to Xi.) The Chinese have opportunity to rewire their trade, but it is not something that changes over night. They have a lot of prejudice to get past - and other economies are concerned about the impact of depending on the Chinese.
Mabe the rumours of him losing power are true? Does the CCP have a statement?
