Latest NAFTA round to end without trilateral statement -sources

MEXICO CITY, March 5 (Reuters) - The latest round of talks to revamp the North American Free Trade Agreement will conclude without a trilateral statement from the United States, Canada and Mexico, like the last round, two sources with knowledge of the matter said on Monday.

The latest talks, which began in Mexico City last week, have been clouded by U.S. President Donald Trump's plan to impose tariffs on steel and aluminum imports. Canada and Mexico have threatened retaliation unless they are exempted. (Reporting by David Ljunggren and Lesley Wroughton Writing by Julia Love Editing by Paul Simao)
