Mexico, Canada and the European Union on Tuesday condemned U.S. President Donald Trump's decision to impose tariffs on all steel and aluminium imports next month, a move that has fanned fears of a trade war.

The effort is one of a number of actions taken by Canada amid rising concerns of a trade war with its neighbour.

Ms Sheinbaum (pictured) won praise at home and abroad for her handling of her mercurial American counterpart. Throughout the confrontation her demeanour was respectful but firm. When Mr Trump ordered tariffs on February 1st, she told her team to prepare countermeasures, but did not publicise the details.
