Projection. China does not even try to export their ideologies to the rest of the world who they see as clearly different culturally. The “west” OTOH does not have a good track record of that.
It's interesting how this sounds like projection to me as well, from the perspective that China does export their ideology. Your post itself seems to be a form of that, whether you're Chinese or not.
China certainly does export their ideologies by telling the world Taiwan is part of China and telling others to not recognize Taiwan as a country. They also have major if not direct influence on Myanmar's civil war. North Korea. Let's not forget the taking land(India, tibet) and extending their borders with man-made islands so they can extend their fishing territories. that's a great track record. you're not biased at all.
Most European countries did awful things during their colonial years, some late into the XX century. Some still do shady things in Africa right now. And they all welcome money siphoned off peripheral countries by crooks.
I see Chinese citizens traveling abroad every day. Doesn't look like they cannot travel. Freedom of what exactly? Are you really free in America when you have to toil away 12 hours per day to make ends meet? Honestly funny to see people falling for American propaganda.
They only let some of them out. And it's hard to get a passport. Most other countries work the opposite way. You need approval to enter. In China, you need approval to exit.
One way to think about it: if every country prevents people from entering, the effect is exactly the same as one country preventing people from leaving.
Communism is a political and economic ideology aiming for a classless society where the community, rather than individuals, owns major resources like factories and land, distributing wealth based on need.
