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.

MEXICO CITY (Reuters) - The 25% tariff on steel and aluminum imports from Mexico imposed by U.S. President Donald Trump "is not justified" because the U.S. runs a steel and aluminum trade surplus with Mexico, Mexican Economy Minister Marcelo Ebrard said on Tuesday.
