Canada must have an “urgent rethink” of its relationship with China, former prime minister Brian Mulroney said Wednesday as tensions build over the possible extradition to the United States of Huawei executive Meng Wanzhou.

Conservative Mulroney backed his Liberal successor Justin Trudeau’s rejection of any exchange of Meng, who was arrested in Vancouver in December 2018, for two Canadians who were detained in China in apparent retaliation.
