Jean Chrétien is floating the idea of having Canada’s Justice Minister exercise his legal authority to stop the U.S. extradition of senior Huawei executive Meng Wanzhou as the means to normalize diplomatic relations with China, sources say.The former Liberal prime minister, who last week offered to serve as Canada’s special envoy to China to help free two jailed Canadians, has discussed the idea of cancelling the extradition process with business executives, according to sources with knowledge of the conversations.The proposal was first raised by University of British Columbia professor Wenran Jiang. Mr. Chrétien’s former senior adviser Edward Goldenberg, an Ottawa lawyer, has sought input on it from other China experts, sources say.
