Todays global trade is so complex that markets are confuced and take precutionary withdrawl to offset any outfall, this evantually create panic in market and cuse the crash. However i dont see any trade war between China and US as it is not in intrest of both countries. China need growth and US is the biggest customer of China. By imposing taxes on imports from China goods US is boosting inflation into its economy which is not good. Trump administration is unpreditcable they want attention of voters to show them that we blocked china you go produce your own. Which is very difficult and pricy now.
