BEIJING, Nov. 15 (Xinhua) -- The multi-party cooperation system is an inevitable choice in China's social development, says a white paper published by the Information Office of China's State Council on Thursday.

The white paper, first of its kind, detailedly introduced the multi-party cooperation system.

The paper, entitled China's Political Party System, reviews the history of the party system's establishment in China, saying Mr. Sun Yat-sen concluded that China could not simply copy European and American politics to govern its own society, as Chinese society was different from that of the West after a parliamentary and multi-party system in imitation of that in Western countries introduced by Sun collapsed in China.

It also notes that the Kuomintang headed by Chiang Kai-shek exercised one-party dictatorship and monopolized all state power between 1927 and 1949, which was finally abandoned by history.

"The political development of modern China called for a new political party system that suited China's national conditions. Such a historic mission fell on the shoulders of the CPC (Communist Party of China) and its eight partners," the white paper says.

The eight democratic parties are: Revolutionary Committee of the Chinese Kuomintang, China Democratic League, China National Democratic Construction Association, China Association for Promoting Democracy, Chinese Peasants and Workers Democratic Party, China Zhi Gong Dang, Jiu San Society and Taiwan Democratic Self-Government League.

In the days of tough struggles, the CPC has established and developed close relations of cooperation with the eight democratic parties and joined forces with them to fight for peace and democracy.

In April 1948, the CPC's proposal to convene a new political consultation conference and set up a democratic coalition government was warmly endorsed by the democratic parties and democratic personages without party affiliation. They made it public that they were willing to strive to build a new China under the leadership of the CPC, according to the white paper.

The convention of the first Chinese People's Political Consultative Conference (CPPCC) in September 1949 marked the formal establishment of the multi-party cooperation system under the leadership of the CPC. It also marked the beginning of the CPC, the democratic parties and the democratic personages without party affiliation working together in building the state power of New China, says the white paper.

"Since the founding of New China, the multi-party cooperation system has been continuously developing and consolidated, and is playing a significant role in the state's political and social life," says the white paper.
