BEIJING, Oct. 23 (Xinhua) -- The Political Bureau of the 17th Central Committee of the Communist Party of China (CPC) held its first plenary session on Tuesday to arrange the implementation of the Party's policies established in the 17th CPC National Congress.

The meeting underlined that the most important task for the Party after the congress is to publicize and implement spirit of the 17th CPC National Congress.

Presided over by Hu Jintao who remains head of the CPC Central Committee, the meeting called for all party members to be fully engaged in realizing Party's objectives established in the congress.

The meeting urged Party organs at all levels and all circles to earnestly study Hu Jintao's report delivered at the opening ceremony of the congress and the newly revised Party Constitution.

The Politburo asked Party members to profoundly understand and continue to promote the scientific outlook on development on the basis of social harmony, environmental protection and energy conservation in addition to economic expansion.

The outlook has been newly incorporated into the Party's Constitution which also enshrined Marxism-Leninism, Mao Zedong Thought, Deng Xiaoping Theory and the important thought of Three Represents.

During Hu's previous tenure as general secretary of the 16th CPC Central Committee beginning November 2002, Hu and his eight colleagues of the Politburo Standing Committee went all out to promote the scientific outlook on development.

The outlook should be carried out in every field of economic and social development, the Politburo said.

The meeting especially stressed that Party organs and members at local level should work out new measures of reform to solve practical problems that common people most concern about.

It is important for the Party organs at all levels to enable more people to share achievements in economic development, the Politburo asked.

The Politburo also asked Party members in local enterprises, educational institutes, communities and military units to mobilize the public to learn and understand the Party's tasks set at the 17th Congress.

The first plenary session of the 17th CPC Central Committee on Monday elected the new politburo and its Standing Committee in which four new members came to the Party's top leadership.
