The troubled course of the revolutionary process of building socialism in China reveals a gradual reorientation of revolutionary energies to the "technical tasks", focused on economic development and increase of productive forces. The theoretical and practical reframing of Chinese socialist transition acquires a qualitative dimension with the proclamation of the Reform and Opening policy and the recognition of the historical phase that the Communist Party of China, since Deng Xiaoping, defined as the primary stage of socialism. The economic reformulation stresses the issue of the use of market instruments in the process of socialist transition in China, establishing a parallel with the pioneering experience of Soviet NEP. The socialist market economy in China corresponds to a model of mixed economy, in which public ownership and the State hold the commanding heights of the economy, and the integration into the world economy is a key lever. This reality that does not set as granted a return of China to the dominance of capitalism. At the same time, the inevitable clash between the dynamics of two conflicting economic systems – socialism and capitalism – raises to the CCP and the Chinese proletariat the theoretical and practical requirement of safeguarding a re-updated class perspective.
