Communism, as you described, is an ideal. An horizon, a direction to walk. Therefore, it never was achieved, and it is not expected to be achieved in any short term. So, it does not make sense saying that only after abandoning communism China rose. What they abandonned was a soviet flavour of socialism. Communism never existed (at least not the flavor that you described), but it is still an inspiration and source of values. Perhaps in a far future, with more technology, and without existing an upper class above a lower class this could be possible.
