NEW YORK, July 31 (Xinhua) -- U.S. President Donald Trump on Thursday signed an executive order further modifying tariff rates with nearly 70 trading partners.

The order hereby imposes "additional ad valorem duties on goods of certain trading partners."

Most of the new tariff rates range from 10 percent to 40 percent, according to an annex to the release from the White House.

The new tariff rates will take effect seven days after the date of the executive order with exceptions on logistical grounds.
