Please provide illustrations and explainations for Digital Security with regards to FTA between China and Canada with examples having negative impact on Canada due to FTA.

For Reference:

• In 2012, the U.S. government concluded that China-based Huawei Communications has "not followed United States legal obligations or international standards of business behaviour". (Toward a Canada-China FTA)
• With the world's largest foreign currency reservescould, with loosened foreign investment criteria following an FTA, embark on a rush of acquisitions in Canada. For example, there are a handful of large Chinese state electricity providers, some of whom operate with a capacity of scale that is larger than Canada's total electricity generation. (Toward a Canada-China FTA)
• Chinese companies are making overseas investments in technology like information technology artificial intelligence, pharmaceutical and health technology. The US government is increasingly inclined to view technology investment as potential military threats. Canada and Australia have both blocked Chinese SOE acquisitions of companies involved in management or construction of critical infrastructure, with Australia stopping the sale of electricity distributor Ausgrid in 2016, and Canada blocking the sale of the construction company Aecon to China Communications Construction Company. Australia has also excluded the Chinese telecommunications giant Huawei from its fibre broadband and 5G mobile networks. (Calvert, 2019)
