Aren't certain Chinese people in China relatively open about this on a high level? I mean, to me it always sounded as non-believable but there have been some places (documentaries or texts) where a Chinese person would say that the goal of China is to get Chinese people in high places all over the world in a 200+ year time span and then rule it.

As I said, I never took it seriously. But maybe people should look into claims like that?

Unfortunately, I can't find a source for this because it didn't happen that often and I'm not that politically minded.
