Donald Trump is aggressive to decouple from China rather than XI Jinping. But both of them want control over everything. That's why the world economy is upset right now. What Trump fails to understand that without China or Chinese electric support the overall cost of production will increase substantially. The real question is if Trump loses this year... Will this situation change?
Nope, that is not possible since the US have a law already restricting a person to be running twice as a president.

Both countries needed each other for the sake of economy growth especially this time where there's a pandemic that causes a lot of damage not even in the economy but also to the people's health.
