President Enrique Pena Nieto did not address reports that he was considering" canceling next week's visit to Washington following Trump's order to begin construction of the wall between the two countries.
In a recorded address televised nationally, Pena Nieto said "I regret and reject the decision of the US to build the wall."
Earlier Wednesday, an official, who was not authorized to discuss the matter publicly and spoke on condition of anonymity, told The Associated Press the administration "is considering" scrapping the Jan. 31 visit.
Trump's order came the same day Mexico's foreign relations and economy secretaries arrived in Washington for talks.
