Beijing: China warned Canada on Friday that it needs to be aware of the consequences of aiding the US in an extradition case involving Chinese tech giant Huawei that is believed to have sparked the detentions of two Canadians in China.

Foreign ministry spokesman Geng Shuang's comments came after US Vice President Mike Pence and Canadian Prime Minister Justin Trudeau called for the release of Michael Kovrig and Michael Spavor. Both were arrested on December 10 after Canada detained a Huawei executive wanted by the United States on fraud charges. While China has denied they were taken in retaliation, it has repeatedly implied that there is a strong connection between the cases.
