"I believe the China is the longest surviving political entity."

By my standards, what we today call China dates to the 1949 Communist revolution. For China to be able to claim continuity, the other side would have had to have won. "Polities located vaguely in the Chinese landmass area" is not an institution.

"China has caught up in many many ways and starting to out innovate even the US. And they're just getting started."

I'm not seeing a lot of evidence of innovation. What I see is a Communist country doing what Communist countries do, living off of the innovation of others while pouring a lot of effort into PR that confuses credulous Westerners who really want to believe. I believe the Chinese people are capable of innovating, but until they structure their society differently, it isn't going to happen. It is an interesting question as to whether the Chinese people could tolerate and/or adjust to a truly high-innovation culture, but that's a PhD-thesis-sized topic.
