My Lords, the Minister will be aware that we have something in the region of 110,000 Chinese students at our universities. In some universities, they take up almost 50% of the places on courses such as those on artificial intelligence, stealth technology and quantum mechanics. Is she concerned that we are not clear about, or aware of, exactly where some of these students have come from? For example, postgraduates are paying £50,000 to do the courses. There are therefore risks of technology being sucked away from this country.
