>China is not doing anything to the US

In many cases the ownership has been traced to government funding. The suspicion is that these are just the tip of the iceberg.

So, at least in the eyes of the US Congress, based on some damning evidence, China is doing something to the US.

That said, "black money" is also a problem. But I suspect that's the case in China as well. There's no way to eliminate all corruption, even in China.
