US President Donald Trump is preparing to impose new tariffs on dozens of countries, according to a report in the Financial Times.

The move could come as early as this week, coinciding with the scheduled expiration of a temporary 10 percent global tariff on Friday.

The most immediate duties are expected to be on a similar scale. However, the administration is reportedly pursuing other investigations that could provide legal grounds for higher future tariffs.

Reuters could not immediately verify the report.
