Trump announced the Vietnam deal on Wednesday, saying that the US would place a 20 per cent tariff on Vietnamese exports to the US and a 40 per cent rate on goods deemed transshipped through the nation — a reference to the practice whereby components from China and possibly other nations are routed through third countries on their way to the US.

On April 9, President Donald Trump gave the world a three-month window to negotiate trade deals with the United States or face higher “reciprocal” tariffs. With just five days remaining in that tariff moratorium, the White House is expected to begin delivering a message to a dozen or so countries: Time is up, and here’s your new tariff rate.

American tariffs on dozens of countries will come into effect next Wednesday as scheduled, although several deals could still be worked out before then, President Donald Trump confirmed Friday.
