Canada's defence minister says he doesn't see China as an adversary as an international security conference prepares to focus heavily on the Asian superpower during its weekend gathering in Halifax. Harjit Sajjan says while there are significant challenges in Canada's relationship with China - including the detention by the Chinese of two Canadians - now is the time to try to work together to find solutions. However, Halifax International Security Forum president Peter Van Praagh says China can be characterized in a variety of ways from competitor or strategic competitor to adversary. Van Praagh says he thinks it’s clear that Canada and China do not share the same interests.
