And there may have been another similar case, I can't recall. I believe the US line is that China was trying to steal research or something. I don't believe any of the people implicated were charged with treason or spying or anything like that. It's been more mundane "failing to disclose bank accounts" kind of stuff. Whether that's indicative of anything is up in the air.
