As far as "Chinese style" surveillance, I always note that it's always western or western-friendly information sources giving us the information on it. It's always filtered according to someone's interests, so when I subtract that from the issue I'm left with an estimation that it's probably not appreciably different than what we have in the US.
The government has already managed to get numerous key parts dismissed under state secrets privilege. [3] The government was also directed to preserve key data related to what remained of the case. In 2018 they informed the court they'd accidentally deleted it. Oops. [4] Oh yeah, in the same statement they also acknowledged they lied under oath when previously stating that they had preserved all relevant data on magnetic tapes and stored them with counsel. Oops again! Penalties.. consequences? You can guess.
And yes, you can also sue the government in China. Just don't expect to win.

And China isn't going to downplay the speculation. Frankly, they want everyone to think they have the best, most thorough surveillance apparatus in the world. Even if it isn't stronger than what is done here, the perception is to their benefit.
> Data, both content and metadata, that already have been collected under the PRISM program, may be searched for both US and non-US person identifiers.
There were many such programs that collected the data itself, as revealed by Snowden. PRISM is just the first that came to my mind.

The evidence is not too hard to find. This [1] site provides an extensive and ordered collection of most published Snowden related documents. It's also quite nice since it ties the documents to the first press coverage as well, if you'd rather peruse something other than the raw data. There seems to be a curiously large amount of misinformation on this topic, but when you actually look at the evidence - this situation is not in the least bit ambiguous.
These [2] slides give a broad overview of what PRISM is:
- Slide 3 describes PRISM: "PRISM -Collection directly from the servers of these U.S. Service Providers: Microsoft, Yahoo, Google, Facebook, PalTalk, AOL, Skype, YouTube, Apple".
- Slide 5 describes what is collected: "What will you receive in collection (surveillance and stored comms)?" - "in general" : "email, chat - video + voice, videos, photos, stored data, VoIP, file transfers, video conferencing, notifications of target activity - logins, etc, online social networking details, SPECIAL REQUESTS (caps added here to represent the bolding in the slide)".
This [3] is a document entitled "User's guide for Skype PRISM Collection". It gives some insight into how the program operates from an operative level including screenshots. It details surveillance of skype conversations, including conversations between skype and a landline connection. In skype-skype connections surveillance is available for audio, video, chat, and file transfers. It also mentions another program "DECODEORDAIN" which apparently maps different email addresses to a single person (used when engaging on surveillance on a target with skype registered under multiple email accounts).
That document also details that as data goes from Skype's servers, it also goes directly to the NSA. So this leads to situations where their agents can apparently become a bit confused about receiving multiple copies of the same chat log. That might happen, for instance, when a user logs onto a different device and his chat history is resyced so it goes from Skype to him as well as to the NSA. That's all made even more interesting by the fact that this was back from 2011 when Skype was still peer to peer. So while we get hints of how their process worked, the exact mechanisms are still a bit obscured.
There's a lot more really interesting stuff as well, but you could spend years going through all of it. Anyhow, suffice to say - no the government isn't just collecting just metadata. Anybody that says that is spreading misinformation either intentionally, or because they themselves have been misinformed and now think they're informing others.
