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.

China has the Great Firewall segregating most international access from the country's network. Additionally, China (moreso than most) has a motivation to onshore as much of their software and hardware manufacturing to bolster their own industry.

It's possible that isolated attacks could pop off now and again, but hacking to-and-from China is strictly state controlled.
