A low-key meeting was held in Ottawa this week as senior officials from Canada and China attempted to mend the deteriorating ties between the two nations, Reuters reported, citing Canadian officials. The relationship soured earlier this year after Canada accused Chinese hackers of being responsible for an attack on a government computer and China detained a Canadian couple, the Garratts, on suspicion of spying. Canadian Prime Minister Stephen Harper is set to attend a November Asian regional summit in China, but a well-placed Canadian official said the idea was now in doubt due to the detainment of the Garratts by the Chinese.
