Thanks, Chair.
Thank you, Mr. Vigneault, and the whole panel here, for attending today. It's a very important conversation.
Mr. Vigneault, I appreciate the work that you do. I know you testified at the procedure and House affairs committee when we did extensive work on foreign interference. I really appreciated your and Ms. Giles' testimony there.
You mentioned an increasingly complex threat environment, which I think we can all agree is the case. Really, it is at the heart of where our concerns are coming from. I think you said the PRC is the most sophisticated actor. You've also mentioned an ecosystem approach.
I think sometimes people are looking for a very simple solution for a very complex problem and a very complex risk environment that are evolving quite quickly. This is what I've heard from you in the past. I've heard you reiterate that today.
Could you speak, Mr. Vigneault, about the importance of that ecosystem approach and why that's more effective than, say, something like a blanket ban, which is perhaps not the most effective approach?
