Short Version; lets face it All governments lie and suppress the truth (and in some cases the people) and If China isn't in the top 6 most of us would be very surprised.
You're right and your wrong there. Yes all governments lie. However not all governments will willfully allow their citizens to die to stay in power. So it's a yes and a no.
The Chinese government is threat to humanity, like global warning etc. The only reason you don't hear about them is because of money, i.e greed. They are a scourge. I'm going to take a guess here that nobody, no posters here have lived under an authoritarian regime.
What we're are participating in now, you have no idea. Having a wee chat with your neighbor, if you criticized the government he might be a paid informer and you are disappeared. You're family have no avenue of re-dress. Want to post on social media that disagrees with government policy. Next day you're gone. And it continues.
The Chinese government are lying. Lying through their teeth. And yes, they are the biggest threat Western nations have faced since Nazi Germany. They are a genocidal government intent on complete control of their populace and they seek to expand.
They'll follow the inevitable steps that all repressive regimes take and make a scapegoat to keep their populace compliant.
