Don't you see what Trump is doing?
He just isolated China and they fell right into the trap.
1.
all the other countries that wish to do business with the US have a reprieve from the tariffs, opening up trade for products with said countries that we normally import from China, effectively cutting China off. How quickly we can get up and running with the countries willing to play ball is up for debate, but I would imagine it will be rather quickly if we know Trump
2.
Trump will no doubt give companies and countries tax incentive to bring factories and manufacturing back in the US. That will also hurt China, as I'm sure their behavior will make Trump less likely to extend the incentives to them.
3.
Boosting oil and gas production, coupled with deregulation, will also help the US become a manufacturing powerhouse once again. Being more self reliant will also stick it to China.
The master of Art of the Deal is chopping up China.
