Anytime someone starts talking about the magic of the market I know they are lost and clueless. Read Marx's Grundrisse for starts . SURPLUS VALUE comes from exploiting workers labor input. Pretty basic....no mystery or " magic". As for China it is still a Centralized Planned economy and they took advantage of capitalist markets true but still Central planning used those profits to build the rest of their society. You certainly can't say that for the capitalist economies like the USA.
