The Huawei company has quite a strong connection to the Chinese military; its CEO is a former military man. There are concerns as to why the Chinese government is so resistant to the Huawei CFO's being sent to the United States, out of perhaps fear she would provide evidence to the U.S. government about Huawei's connection to the Chinese military and security apparatus.
We have concerns that Huawei could get knowledge of key Canadian infrastructure in the course of its installation of a system or would be able to use it for purposes of data collection and cyber espionage, as we've seen with the Chinese government's previous hacks into the NRC and, before that, the Treasury Board and other agencies. It's a big concern, and I certainly wouldn't like to see Rogers renamed Huawei.
The other problem is that, even when you have these large takeovers, it's difficult to get the state companies to abide by their commitments. As seen in Nexen, there was a commitment to maintain the existing Nexen management, but after a while, we saw the Canadians were removed and the management was assumed by Chinese communist officials, so it's highly problematic.
With regard to your question of whether we should allow Huawei to take over a major Canadian telecommunications provider, I would like to say a capital no with several exclamation marks.
