Canada has asked the United States not to sign any final trade agreement with China until two Canadians detained in China have been released, Prime Minister Justin Trudeau told a French-language TV network. It has been more than a year since Beijing detained Michael Spavor and Michael Kovrig in apparent retaliation for Canada's arrest of a top Chinese tech executive, Meng Wanzhou. In a wide-ranging interview with The Canadian Press Wednesday, Trudeau said the case has impacted Canada-China relations at virtually every level, and that while regretted that Kovrig and Spavor have been caught up in the diplomatic row, he didn't regret that Canada lived up to its extradition treaty with the United States.
