As I mentioned before, Canada does have rather broad authority after the fact to review transactions—in Canada, more blocking than mitigation, for reasons that have been discussed today. Canada, I think, was one of the earlier countries to actually take action.
I do think, looking at the U.S. experience, that we closed what we thought was a loophole, particularly with respect to high-risk technology, to be able to review those preclosing. I think it's important to have authority to review at least some of those transactions before the foreign persons of concern actually have the ability to access the technology or the data, but I will say that, as I mentioned before, there's a pretty broad scope in terms of how much is being required preclosing. I think you almost always see dual use in high tech. Some countries include agriculture. Japan has leather goods. You see variations there, but I think some ability to review the transactions before closing is important.
