U.S. Trade Representative Jamieson Greer said technical talks with Canada were continuing but that a handful of outstanding issues were quite difficult to resolve, speaking as the G20 trade ministers' meeting closed in Milwaukee.

Asked whether Washington was consulting U.S. automakers about a 50 percent tariff on Canada's auto sector on January 1 absent a deal, Greer said U.S. trade policy was focused on re-shoring manufacturing.
