After the founding of the PRC, the CPC led the nation to make constant progress: triumphing over repeated threats, sabotages and armed provocation of imperialists and hegemonists, safeguarding the nation's independence and security; successfully achieving a great transfer of the Chinese society from new-democratism to socialism, accomplishing, in a general sense, the socialist transformation of the private ownership of the means of production; and launching the large-scale socialist economic construction in a planned way, and enabling Chinese economic and cultural causes to attain unprecedented development.
Beginning in 1979, China introduced reforming policies advocated by Deng Xiaoping and opened its door to the outside world. The "left deviation" errors made during the "cultural revolution" and before were redressed, and the focus of the work was shifted to the modernization drive. Great efforts were made to regulate the proportions within the national economy, reform economic and political systems and gradually establish a road to build socialist modernization with Chinese characteristics. The past two decades have witnessed substantial changes in China. It is the best period that China has ever experienced since 1949 and also the period when the people of China received the most substantial benefits.
