Canada plans to ask the World Trade Organization to set up an adjudication panel to judge its dispute with the U.S. over lumber exports, indicating that talks have failed to resolve the issue.

The Trump administration says Canada's trade threats will not influence the course of action the U.S. takes in the lumber dispute.
