Idon't think that's a warship (although I do concede it's gathering intel) and it's a 1500km boat ride away from Canada's territorial waters.

1500km is about twice the length of Canada's pacific coast (Southern tip of Vancouver Island, to Northern tip of Haida Gwaii)

My view is that the condition of the arctic ice cap is of global interest, but China's claim to be an arctic nation is total garbage.

Canada probably should take steps to further assert sovereignty over its arctic archipelago (and the associated searoute), but I still feel that the comment I was responding to was spreading alarmist junk.
