Donald Trump is falling in the pit he has made. It is a guarantee that Trump shirts are made in China. How can a person negotiate best for his country when he has a conflict of interest. I hope that Trump completes his term and steps down instead of running for the second time.
Your arguments look like a nonsense. In the world where every country is embraced with ties of globalization you can say that in some sense you have conflict of interest with any country because you're trying to sell goods each other, and unfair trade policy will lead to the outflow of welfare from your country. Well-played protectionism is best strategy for a country to be prosperous.
