Canada's extraordinary arrest one week ago of Huawei CFO Meng Wanzhou, the daughter of Huawei founder and billionaire executive Ren Zhengfei, and its decision to charge her with "multiple" counts of fraud - a preamble to her likely extradition to the US to face charges of knowingly violating US and EU sanctions on Iran - has elicited widespread anger in Beijing, which declared Meng's detention a "violation of human rights" during a bail hearing for the jailed executive on Friday.

That anger has apparently only intensified after the hearing adjourned without a decision (it will resume on Monday, allowing Meng's defense team to argue for why she should be released on bail, contrary to the wishes of government attorneys who are prosecuting the case).

And with Canada insisting that it will prosecute Meng to the full extent of the law over allegations that she mislead banks about the true relationship of a Huawei subsidiary called Skycom, angry Chinese officials have decided to issue an ultimatum directly to the Canadian ambassador, who was summoned to a meeting in Beijing on Saturday and told in no uncertain terms that Canada will face "severe consequences" if Meng isn't released, according to the Wall Street Journal.
