Days after the arrest, China detained two Canadian citizens — businessman Michael Spavor and Michael Kovrig, a former diplomat and an adviser with the International Crisis Group — whom it is investigating for endangering its national security.
In an article in the Ottawa-based Hill Times newspaper on Wednesday, Ambassador Lu Shaye said Canada's demands for the release of the two men reflected "double standards" born of "Western egotism and white supremacy".
Lu wrote, "It seems that, to those people, the laws of Canada or other Western countries are laws and must be observed, while China's laws are not, and shouldn't be respected."
A lack of concern in Canada for Meng suggested that humanitarian treatment was only deemed necessary for Canadian citizens, not Chinese people, he added.
China has not drawn a direct link between its detention of the two Canadians and Meng's arrest, but Beijing-based Western diplomats have called the cases a tit-for-tat reprisal.
