Hitch emerges in key Mexico-US accord

A top Mexican trade negotiator flew to Washington on Sunday for urgent talks as a hitch emerged in the U.S.-Mexico-Canada Agreement, just days after it was signed.

Jesús Seade, undersecretary for North America in the Foreign Ministry, accused the United States of blindsiding Mexico by deciding to send up to five U.S. attaches to monitor labor conditions as part of the treaty, the Washington Post reports.
