First, let me fix your question
>How is China going from a feudal agriculture state to a Rich Superpower ?
The answer: by exploiting the greed and corruption of our political and business class, so that they make deals to the benefit of China and to the detriment of the United States, in order to personally enrich themselves.
In simple terms, the Chinese are very skilled at bribery and subversion. They are very aware of our leaders' lack of love for our nation or our people, and they exploit it.
Even so, China is a paper tiger. Its economy is parasitically dependent on exports to the US, and the vast majority of its billion+ population are still illiterate rice farmers.
China is not a super power.
