The pause on the biggest of Trump's tariffs won't pass this week, as planned, but the problems they present still loom large.

A nother deadline passed on Wednesday without President Donald Trump following through on his threats to impose new tariffs. It was 90 days ago that Trump had announced an abrupt pause in his plan to levy new tariffs on countries around the world.

U.S. President Donald Trump has sent letters to Canada and a handful of other countries this week outlining higher tariffs they'll face if they don't make trade deals with the U.S. by Aug. 1.
