With regard to the question of the security threat, there is no question in my mind that the Chinese government seeks capabilities that may be useable if its intent comes later. Capability plus intent is a threat.
In the installation of these very reasonably priced X-ray systems and so on, aside from the concern that CSE raised the last time about USB ports or hard drives inside, there's also just the idea that people who are possibly agents of the Chinese regime would have the opportunity to spend a lot of time in embassy premises—at the door, potentially interfering with the equipment or installing phone chips and that kind of thing—which I think in general the Chinese regime would see an opportunity, in having the ability to access the embassy.
I have heard of a Chinese-installed streetcar system in Britain in which the company found out to their surprise that in fact, on the basis that they needed to service it, the streetcar system was connected to China via a telephone link, which would allow people in the city of Nanjing to stop and start those streetcars remotely.
I think they want that kind of capability, not necessarily because they have the intent to use it immediately, but because there is the potential to make use of this as an opportunity for the Chinese state to realize its geostrategic purposes in the future.
Let me say one other thing. As someone who spent a lot of time in China—I was educated in China—if I went to an embassy and saw that I was being scanned by a Chinese-manufactured machine, I would be quite reluctant to go in, just because of the potential of using sophisticated artificial intelligence and so on to monitor, as we have seen with this kind of equipment as it's used in places such as Xinjiang against the Uighurs.
I think in general we have to be very cautious about any firm that is connected to the Chinese state.
