U.S. President Donald Trump said on 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.
