The US and Mexico trade negotiators on Friday concluded their first bilateral negotiating round to revise the US-Mexico-Canada Agreement on trade, discussing automotive rules of origin, steel and aluminum trade and economic security, the US Trade Representative’s office said.

The trade agency said that the two sides will continue to advance their discussions on June 16-17 in Washington, DC, in talks covering agriculture and “a level playing field.” A third round is scheduled for the week of July 20 in Mexico City, but so far the talks exclude USMCA partner Canada.
