The high % of people polled concerned with possible Chinese "takeovers" of Canadian companies that make technology with military applications seems to rest on an old fear of China, as "other", or even as the "great yellow peril". There is ZERO evidence that China has any interest in militarily attacking Canada, the US, Europe, or large parts of Africa, the Middle East, and Asia. Like the US, and previous global empires such as those of the UK, France, the Incas, Turkey, ..., China wants to become a regional power that can keep its own regional empire safe. It is more likely to use economic than military means. Those people who raised issues about Chinese takeovers of such Canadian technology companies might want to look in the mirror, and ask themselves why they are so afraid of China, yet somehow are happy to have the US takeover the same companies. Given water and energy issues, we are far more likely to be attacked militarily by the US in the future.
