Canadian Prime Minister Justin Trudeau has fired his Chinese ambassador, John McCallum, after the ambassador made several comments regarding the controversial arrest of a Huawei executive in December, saying that she has a strong case to oppose extradition.

Back in December, Canadian authorities arrested Huawei CFO (and daughter of the company’s founder), Meng Wanzhou, who also served on the board of a Hong Kong company, Skycom. That company allegedly did business with Iran, and prosecutors say that because Huawei did business with US banks, she violated US sanctions against the country. Meng was granted bail in a Canadian court shortly after her arrest, and remains in British Columbia while the US attempts to make a case that she should be extradited to stand charges here.
