China
China's constitution states that The People's Republic of China "is a socialist state under the people's democratic dictatorship led by the working class and based on the alliance of workers and peasants," and that the state organs "apply the principle of democratic centralism." The PRC is one of the world's only socialist states openly endorsing communism (see Ideology of the Communist Party of China). The Chinese government has been variously described as communist and socialist, but also as authoritarian and corporatist, with heavy restrictions in many areas, most notably against free access to the Internet, freedom of the press, freedom of assembly, the right to have children, free formation of social organizations and freedom of religion. Its current political, ideological and economic system has been termed by its leaders as the "people's democratic dictatorship", "socialism with Chinese characteristics" (which is Marxism adapted to Chinese circumstances) and the "socialist market economy" respectively.

The concept of a primary stage of socialism was developed mainly by Xue Muqiao and Su Shaozi. The concept began to evolve when the new post-Mao leadership of Deng began questioning Mao' assertion that "class struggle as the key link". Su, coauthoring with Feng Langrui, published an article in "Economic Research" () in 1979 which called into question the Chinese socialist project by using Marxist methodology. The article analyzed the basis of Chinese socialism by looking at Karl Marx's writings; Marx drew a distinction between lower-stage communism (commonly referred to as the socialist mode of production) and higher-phase communism (often referred to as simply communism). Su's and Feng's article created three subdivisions within the socialist mode of production; the first phase was the transition from the capitalist mode of production to the socialist mode of production; which was (a) the phase in which the proletariat seized power and set-up the dictatorship of the proletariat and (b) in which undeveloped socialism was created, the second phase was advanced socialism (the socialism of which Marx wrote about). They argued that China was an undeveloped socialist nation since;
