50 years ago, British companies' money corrupted a UK university. Now, China has the money to suck them into a system of corruption.

Something similar has happened in Australia, and I expect it is happening in the US as well.

Meanwhile, China exercises its tyranny over Chinese students studying abroad.

I would not want universities outside China to exclude Chinese from studying or cut off Chinese labs from research collaboration. But we must make sure they can't get sucked in to the point where they don't dare say no when they must.
