Political scientists believe that propaganda in the PRC is being utilized by the CPC to nurture the development of Chinese nationalism and of loyalty to the PRC, the CPC, and the Beijing government in general. Many also believe that the PRC government, having embarked on a program of capitalist-style economic reform and modernization in the late 1970s, is keen to use propaganda to portray the CPC as a nationalistic and patriotic party, rather than simply as a party that builds socialism or implements Marxism-Leninism in China, since these have largely been abandoned in practice and thus can no longer serve as effective bases for loyalty to the regime. Common themes in the new nationalistic propaganda of the PRC include the lionizing of the CPC’s People’s Liberation Army and its individual soldiers for their exploits and sacrifices during the 1937-1945 Second Sino-Japanese War and the allegedly seamless unity of the nation’s 56 officially recognized ethnic groups.
