WASHINGTON — President Donald Trump said Sunday he plans talks soon with the leaders of Canada and Mexico to begin renegotiating the North American Free Trade Agreement.

“We will be starting negotiations having to do with NAFTA,” Trump said at a swearing-in ceremony for his top White House advisers. “We are going to start renegotiating on NAFTA, on immigration and on security at the border.”

Trump pledged during his presidential campaign that if elected he would renegotiate the NAFTA trade pact to provide more favorable terms to the United States.

NAFTA, which took effect in 1994, and other trade deals became lightning rods for voter anger in the industrial heartland states that swept Trump to power.

Trade experts, academics and government officials say Canada and Mexico will also seek tough concessions and that NAFTA’s zero-tariff rate would be extremely difficult to alter. Any renegotiation would likely take several years, they say.

Trump said he would meet with Canadian Prime Minister Justin Trudeau and Mexican President Enrique Pena Nieto to begin work on overhauling the deal.

He praised Pena Nieto, who has faced low popularity in Mexico due to corruption scandals and rising inflation.

“The president has been really amazing,” Trump said. “I think we are going to have a very good result for Mexico, and the United States, and everybody involved.”

Critics of Pena Nieto say he lacks a clear plan to counter Trump’s calls to limit trade and deport illegal immigrants.

Trump has said little about what improvements he wants, apart from halting the migration of U.S. factories and jobs to Mexico.

Since winning the election, Trump has singled out and threatened to impose tariffs on U.S. companies that move any production to Mexico.

He has also intends to build a wall along the U.S. southern border to deter illegal immigration and insisted that Mexico will pay for it.

Also Sunday, Trump invited Israeli Prime Minister Benjamin Netanyahu to visit Washington in early February during a phone call in which they discussed the importance of strengthening the U.S.-Israeli relationship, the White House said.

In his first call with Netanyahu since taking office Friday, Trump stressed his “unprecedented commitment to Israel’s security.”

“The president and the prime minister agreed to continue to closely consult on a range of regional issues, including addressing the threats posed by Iran,” the White House said in a statement.

Trump also said peace between Israel and the Palestinians could only be negotiated between the two parties, but that the United States would work with Israel to achieve that goal.

Relations between Israel and the Obama administration ended on a contentious note, when the United States declined to veto a U.N. Security Council resolution calling for a halt to Israeli settlement-building.
