Washington: Washington’s new top diplomat, Secretary of State Rex Tillerson, met his Canadian and Mexican opposite numbers amid concerns over President Donald Trump’s trade policy. Canada, Mexico and the United States are members of the Nafta free trade bloc, which Trump has branded a “catastrophe” for American jobs and has threatened to renegotiate. A State Department statement said Tillerson and Mexican Foreign Minister Luis Videgaray had a “constructive” conversation that touched on law enforcement, migration and security.
