U.S. President Donald Trump said late Tuesday that his administration will unveil new trade actions affecting "a minimum of seven countries" on Wednesday morning, with more nations to be identified later in the day. He made the announcement in a post on his Truth Social platform but did not specify whether the measures would involve new tariffs, trade agreements or other steps. The forthcoming disclosure follows a series of tariff moves by the White House. Earlier Tuesday, Trump announced a 50% levy on imported copper, describing the duty as part of his effort to reshore critical supply chains. He has also warned 14 countries that they must conclude trade deals with the United States by Aug. 1 or face higher duties. Trump’s latest signal underscores the administration’s aggressive trade posture, which already includes a 145% tariff on Chinese goods imposed in April. Markets are watching for details on the countries involved and the scope of the anticipated measures when the list is released on July 9.
