Mexico's government on Tuesday questioned the fairness of a 25% tariff ordered by U.S. President Donald Trump on its steel and aluminum imports, saying that Mexico buys more steel from the U.S. than it exports to its northern neighbor.

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 is preparing to formally announce 25% tariffs on steel and aluminum imports. It's part of an aggressive effort to remake the existing terms of world trade that so far has compounded economic uncertainty.
