The Globe and Mail reports in its Friday edition that U.S. negotiators have told Canada and Mexico they expect to table full details of the Trump administration's demanded changes to the North American free-trade agreement during talks starting this weekend. The Globe's Adrian Morrow, Steven Chase and Greg Keenan write that unnamed sources say American officials served notice to their counterparts during the second round of talks earlier this month in Mexico City that they would present text of all their proposals by the third round. So far, the United States has presented few details on its most controversial demands at the table, sources say. These include a toughening of the rules of origin that govern content in cars, trucks and other manufactured goods, including a possible U.S. content requirement. As well there is a proposal to allow Buy American provisions on U.S. public procurement while fully opening Canadian and Mexican government contracts to American firms. The U.S. also seeks a loosening of Canada's supply-management system for dairy, eggs and poultry. The U.S. also wants to cut its trade deficit. Canada is preparing for the third round as the talks move to Ottawa.
