On December 1st, a business executive named Meng Wanzhou was arrested while transferring through the Vancouver airport at the request of US authorities. Ms Meng is the CFO of the Chinese telecom giant Huawei and now faces extradition to the United States.    About ten days later, a former Canadian diplomat and analyst with the International Crisis Group named Michael Kovrig was mysteriously arrested in China. His arrest was followed by the arrest of another Canadian, businessman Micheal Spavor, under similarly opaque circumstances.    These incidents have plunged Canada into a diplomatic crisis --  and this crisis has implications far beyond Canada, according to my guest today Stephanie Carvin. Stephanie Carvin is an assistant professor of International affairs at Carlton University in Ottawa. She is also the host of a Podcast called Intrepid.   In this episode we discuss both the details of this diplomatic crisis and why what is happening right now between China and Canada is something to which every observer of international affairs ought to be paying close attention.
