Mexico has warned Washington that it will impose tariffs on US products if President Donald Trump taxes Mexican imports to finance a border wall. <br/><br/>Mexican Foreign Minister Luis Videgaray said, the neighboring countries face the biggest diplomatic rift in decades over Trump's insistence that Mexico pay for construction of a wall along their 3,200-kilometer border. Mr Videgaray noted that if Trump places tariffs on Mexican goods, it would hit US households that buy all sorts of products from south of the border, including avocados, cars, phones and appliances. He said, his country is open to discussion on some aspects of Trump's promise to renegotiate the North American Free Trade Agreement between Canada, Mexico and the United States, but will not accept imposed tariffs.
