The U.S. Treasury Department is preparing to expand its secondary sanctions against Iran, potentially impacting businesses and countries engaging with Tehran. The move, expected on Monday, aims to escalate economic pressure on the Iranian regime under the Trump administration. These broadened sanctions will target entities and nations maintaining commercial relationships with Iran. A source familiar with the plans confirmed the impending announcement to Reuters. This expansion builds upon existing sanctions, seeking to further restrict Iran’s economic activity. The intention is to limit Iran’s access to financial resources and ultimately influence its policies. This action represents a continued hardline approach by the U.S. towards Iran.
