Mexico, Canada and the European Union on Tuesday condemned U.S. President Donald Trump's decision to impose tariffs on all steel and aluminum imports next month, a move that has fanned fears of a trade war as business and political leaders braced for yet more trade duty announcements from the new administration.

Mexico will send a message to the United States regarding the 25% tariff on steel and aluminum and top officials are scheduled to speak later this week, Mexican President Claudia Sheinbaum said on Wednesday.

President Donald Trump on Monday imposed a 25% tariff on all steel and aluminum imports into the United States with no exceptions or exemptions.
