Canada has called for the immediate release of two of its nationals detained in China. Canadian Foreign Minister Chrystia Freeland called the detentions arbitrary and a source of deep concern. The two were detained after Canada arrested chief financial officer of Chinese tech giant Huawei in Vancouver. Freeland warned that the detention of the Huawei executive is not political. She added that Ottawa respects its extradition treaty with the US. The Huawei official was arrested after the U-S requested her extradition allegedly for violating anti-Iran sanctions. The US state department echoed Canada’s call on Friday, saying Beijing should immediately release the Canadian nationals.
