Instead on Wednesday, Trump continued to threaten countries with higher tariffs in the near future by publishing open letters to the Philippines, Brunei, Moldova, Algeria, Iraq, Libya and Sri Lanka that set new tariff rates ranging from 20% to 30% that he said he would impose on Aug. 1.

Trump delayed the "reciprocal tariffs" in April, vowing to strike roughly 90 trade deals in 90 days. So far, the White House says it has reached trade agreements with only the United Kingdom and Vietnam, as well as a preliminary accord with China.
