NAFTA talks face big challenges over U.S. demands - Canada

OTTAWA, Feb 8 (Reuters) - Serious challenges remain to be solved at talks to modernize NAFTA, in particular over hard line U.S. demands for major changes, Canadian Foreign Minister Chrystia Freeland said on Thursday.

Freeland told the House of Commons foreign affairs committee that Canada would only accept a deal that was in its national interests. Talks to modernize the 1994 North American Free Trade Agreement have slowed down as Canada and Mexico struggle to address the proposed reforms. (Reporting by David Ljunggren)
