MEXICO CITY (Reuters) - Prime Minister Justin Trudeau said on Thursday (Oct 12) Canada will not walk away from talks to rehash the North American Free Trade Agreement (NAFTA) despite a US proposal to include a clause that could terminate the pact in five years.

Speaking at a news conference with Mexican President Enrique Pena Nieto in Mexico City as a fourth round of talks to renegotiate NAFTA was held near Washington, Trudeau said he was committed to a "win-win-win" deal.

"We will not be walking away from the table based on the proposals put forward," Trudeau said, in response to a question about whether the so-called sunset clause was a poison pill for the talks.
