Trump Speaks to Mexican President by Phone 1 Day After Canceling Meeting Trump and Mexican President Pena Nieto spoke by the phone today.

 -- President Donald Trump and Mexico's president, Enrique Peña Nieto, had a "productive and constructive" call this morning, according to a joint statement released by the White House today.

The two presidents discussed America's trade deficit with Mexico, "the importance of the friendship between the two nations," and the need to work together to stop drug trafficking and illegal guns and arms sales, the statement said.

It also acknowledged the two presidents' "clear and very public differences" on who will pay for the border wall.

"Both presidents have instructed their teams to continue the dialogue to strengthen this important strategic and economic relationship in a constructive way," the statement read.

Trump spoke to Peña Nieto by phone for nearly an hour.

"I will say that we had a very good call," Trump said in a news conference at the White House. "I've been very strong on Mexico. I have great respect for Mexico. I love the Mexican people."

Trump added, "As you know, Mexico with the United States has out-negotiated us and beat us to a pulp through our past leaders. They've made us look foolish."

The two leaders were scheduled to meet next Tuesday, but that meeting has been canceled. Trump signed an executive order Wednesday allowing the construction of a wall on the U.S.-Mexico border and told ABC News' David Muir that Mexico would pay for it.

"If Mexico is unwilling to pay for the badly needed wall, then it would be better to cancel the upcoming meeting," Trump tweeted Thursday morning.

Later that day, Peña Nieto announced on Twitter that he had informed Trump that he would not attend their scheduled business meeting.

During his speech at the Republican retreat in Philadelphia Thursday, Trump said he and Peña Nieto "agreed" to cancel their planned meeting.

Trump, however, said today that he and Peña Nieto have a "good relationship."

"We have really, I think, a very good relationship, the president and I," Trump said in his news conference, adding, "We are going to be working on a fair relationship and a new relationship."

During Trump's press conference with British Prime Minister Theresa May, the Mexican government released a statement in Spanish. It said the U.S. and Mexico had agreed “for now to not speak publicly" about who will fund Trump's proposed wall on the Mexican border.

Later in the day, White House press secretary Sean Spicer told reporters Trump agreed with the Mexican president that they will not speak publicly about how the U.S.-Mexico border will be paid for.

“They agreed not to discuss how it would be paid for publicly, that they would continue to have those discussions privately," Spicer said.
