WASHINGTON (AP) — President Donald Trump on Thursday signed an executive order that set new tariffs on a wide swath of U.S. trading partners to go into effect on Aug. 7 — the next step in his trade agenda that will test the global economy and sturdiness of American alliances built up over decades.

The order was issued shortly after 7 p.m. on Thursday. It came after a flurry of tariff-related activity in the last several days, as the White House announced agreements with various nations and blocs ahead of the president’s self-imposed Friday deadline. The tariffs are being implemented at a later date in order for the rates schedule to be harmonized, according to a senior administration official who spoke to reporters on a call on the condition of anonymity.

After initially threatening the African nation of Lesotho with a 50% tariff, the country’s goods will now be taxed at 15%. Taiwan will have tariffs set at 20%, Pakistan at 19% and Israel, Iceland, Norway, Fiji, Ghana, Guyana and Ecuador among the countries with imported goods taxed at 15%. Switzerland would be tariffed at 39%.

Trump had announced a 50% tariff on goods from Brazil, but the order was only 10% as the other 40% were part of a separate measure approved by Trump on Wednesday.
