U.S. President Donald Trump in an all-caps post on Truth Social Thursday teased a new round of sweeping reciprocal tariffs, matching the higher rates other nations charge to import American goods. …Reciprocal tariffs were one of Trump’s core campaign pledges — his method for evening the score with foreign nations that place taxes on American goods and to solve what he has said are unfair trade practices. …He is set to share more details on the tariffs ahead of his visit with Indian Prime Minister Narendra Modi, White House press secretary Karoline Leavitt told reporters on Wednesday. …The tariffs are likely to hit developing countries hardest, especially India, Brazil, Vietnam and other Southeast Asian and African countries, given that they have some of the widest differences in tariff rates charged on U.S. goods brought into their countries compared to what the U.S. charges them.
