It depends on the issue. On the technical expertise it would certainly be CSE. I do believe they have that expertise now and have provided it in certain select cases but they have to be consulted first.
Then on the geo-economic aspects, I think you wouldn't want to involve an agency like CSIS, which could provide perhaps the broader context and would have knowledge of.... The other thing about these companies too is even when it looks like it's a private company, that just may be a shell company that's owned by layers and layers of different Chinese companies that ultimately end up at an SOE as well. CSIS does have that capability to understand that larger context.
It's not just one, unfortunately, as I think we've all agreed on this panel, but in the meantime, I would definitely, at a bare minimum, be talking to CSE and CSIS.
