Chinese Industrial Espionage

I first saw this a couple of weeks ago. A local businessman is suspected of giving high-speed cameras to the Chinese military. It seems to me this is not an isolated phenomenon. Does anyone know of other cases (other than Wen Ho Lee) around the country? Curiously, the article doesn't mention whether or not Mr. Yu is a citizen of the US. China still has the camera, but it seems to me there's a big difference between spying for one's country and spying against one's country.
