Nafta Talks Left Reeling After Aggressive U.S. Proposals Land

U.S. negotiators in recent days put forth a string of bold proposals -- on auto rules of origin, a sunset clause, government procurement, and gutting dispute panels seen by the other nations as core to the pact. The moves were long-signaled, as was Canadian and Mexican opposition to them.  The proposals have spurred public warnings from prominent U.S. lawmakers and the private sector about the perils of scuttling a deal that over more than two decades has broken down trade barriers, including tariffs, for industries like manufacturing and agriculture.Nafta’s fate may now hang on how flexible the U.S. is about its demands heading into the fifth round of talks, scheduled for Mexico City around the first week of November. While the parties had wanted to reach a deal by December, officials familiar with the negotiations say the talks are likely to drag on for months.
