This is just about what I would expect from governments to behave (both US and China).
This kind of bullshit where people are more concerned about their departments future funding and prospects, and try to bury "unfortunate" incidents is happening in all the governments(and even inside larger companies) I am familiar with. It's a lot easier to bury if you can prevent investigation, than bury results of such investigation. As shocking as might sound this is pretty much businesses as usual in bureaucracy .
For me that doesn't even comes close to Snowden revelations (even though, again we suspected some of it).
