PRC Targeting of Commercial Telecommunications Infrastructure

Whenever I see these news & FBI releases about Chinese state-sponsored hackers breaching systems in America, I wonder whether the same thing happens over there: American malware and hacker groups attacking & laying landmines in China's internet infrastructure, although the Chinese may not publicize these exploits because their system opts to maintain an air of invincibility.

According to Chinese state media, the US installed malware in systems in Chinese universities tied with military, e.g. Northwestern Polytechnical University

According to Chinese state media, Chinese state media is never wrong

Believe it or not, it's up to you; the same goes with FBI

The FBI is not the same as a news agency however.

So that point is null.

Both depend on whether you believe in the government actually. When we say "Chinese state media", we're really talking about a media controlled by the government, especially for those political topics

This would be true even with private actors, at the end of the day it's whoever has concrete evidence of something taking place.

If the FBI is going to make the broad statement that China is hacking the USA, it'll have to back that statement up by evidence presented in court against individuals the FBI has investigated for hacking into US companies/government orgs.

Seems that you just don't believe the other side has done some investigation and therefore did not search for it. I'm not saying that either incident is fake but you've just proved my point of view.
