Obama released Seyed Abolfazl Shahab Jamili as part of the Iran Nuclear giveaway:

Jamili worked with Sihai Cheng. The whole indictment (just found) is here:

There are unnamed Chinese co-conspirators in that indictment, I believe. But there's a larger implication to be drawn from the whole thing: China does not have the capacity to make these objects, and cannot be trusted with that knowledge. You can see this as a trend that has been playing out historically for years. For instance, I found this report from the Senate Select Committee on Intelligence:

It's big stuff, but it shows how China was -very- eager to get a hold of our satellite technology; Reagan allowed them to shoot them into space (cheaper for them to do it), Bush defunded the security component that made sure the Chinese didn't access the technology, and Bill Clinton basically gave the technology away. Also noteworthy is the Chinese attempts at bribery–$300,000 meant to go into Clinton's campaign.
I have a suspicion that the damage that China and Iran can do to Democrats is that they can reveal Democrat involvement in delivering Iran the capability to produce nuclear weapons.
This stems from research I've done on the Obama - Iran relationship. If you want a bigger picture, look here:
