BEIJING, Jan. 21 (Xinhua) -- Senior Communist Party of China (CPC) leader Liu Yunshan on Thursday urged officials to put into practice new development concepts in an effort to achieve the building of a "moderately prosperous society in all respects" by 2020.

Liu, a member of the Standing Committee of the Political Bureau of the CPC Central Committee and president of the Party School of the CPC Central Committee, made the remarks at a closing ceremony of a seminar attended by ministers and provincial officials at the school.

To secure the direction and development pattern for China's economy, the CPC leadership has proposed new development concepts of innovation, coordination, green development, opening up and sharing in the country's roadmap for social and economic development covering 2016-2020.

Liu asked officials to take into full consideration the development concepts while making new policies.

Officials should profoundly grasp the inevitability of the "new normal" of slower growth, and "supply-side structural reform."

The ceremony was presided over by Zhao Leji, head of the CPC Central Committee's organization department.
