US President Donald Trump will announce new tariffs on at least seven more countries Wednesday, with additional measures possible by noon.

This follows warnings to 14 nations on Tuesday, urging trade deals by August 1 or face higher US tariffs. Trump said countries that retaliate will face steeper penalties, according to Firstpost.

While not formal agreements, the letters highlight Trump’s assertive trade stance. Despite economic concerns, he says the tariffs will boost US manufacturing and fund recent tax cuts.

Press Secretary Karoline Leavitt said Trump is personally determining tariff rates and trade plans, Firstpost reported.
