Research the trade war between the US and China during the Trump administration and its impact SPECIFICALLY on international trade.

After introduction of the most prominent policies please focus on:
1. the tariff of exports from China to the US
2. the effect it has on Chinese manufactures
3. Chinese suppliers moving factories to other countries (Vietnam, Cambodia)
4. why this war/imposing tariff is BAD for the world economy
5. other policies imposed that caused the trade war
