To your more general point about the reach of our actions, I think it's true that there is a lot of research that goes on that isn't funded through federal grants.
The prohibitions on federal grants do solve some of the problem. They also send a very clear signal to the research community on where the security concerns are, but we also have, as the minister mentioned, the research security centre, and the funding we've provided institutions has allowed a lot of institutions to actually hire a director of research security so that there's a natural point of contact between the security agencies that can help to identify risks and someone who is responsible for managing those risks at institutions.
It is true that you're not solving the whole problem through prohibitions on federal funding, but there are other layers that have been implemented to try to address those broader risks.
