Various views in the comments + and -.
Mine:
Since 1949 China has been successful to the exact extent that it has allowed the market economy. It has failed to the exact extent that it pursued Marxism. Both Western ideas, one good, one bad.
On corruption, if you believe it's less in China, that's only because they lack transparency.
There's a reason people vote with their feet: how many are desperate to immigrate to China, vs to the US?
ADDED: commenters are from Hong Kong or elsewhere o/s. There’s a reason they don’t live in China. Same for us. We don’t like authoritarian governance. Not even for its alleged benefits to developing economies. Which have always and everywhere done best with clean, fee market governance than with any version of socialism, Marxist or otherwise. (One huge example: post-independence India).
