As U.S. President Donald Trump's new trade tariffs on China, Mexico and Canada kick off, sparking another trade war, countries in Asia's complex and integrated global supply chain are in the crosshairs.

While Trump's tariffs target the three countries to address trade imbalances, nations with the highest trade surpluses with the U.S. are also seen as at risk of further tariffs. In Asia, China, Vietnam, Japan, and Taiwan have the largest trade surpluses with the U.S., according to a recent U.S. Treasury report.

Donald Trump put into place tariffs against Canada and Mexico earlier this week. But after the stock market slipped, he has carved out big exemptions.
