BEIJING, March 4 -- Chinese Premier Li Keqiang and other leaders on Wednesday vowed to fully implement the "Four Comprehensives" strategic layout in order to realize economic and social development targets.

The "Four Comprehensives" refers to a political concept initiated by Chinese President Xi Jinping, which comprises"comprehensively building a moderately prosperous society, comprehensively deepening reform, comprehensively advancing the rule of law, and comprehensively strictly governing the Communist Party of China."

They made the remarks while joining panel discussions with members of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), the country's top political advisory body.

In accordance with the "Four Comprehensives," China should make greater effort to stabilize growth, expand effective demand and withstand downward pressure, in an effort to keep economic operation within a proper range, Premier Li Keqiang told CPPCC members from the economic and agricultural circles.

Reform shall be pushed forward, with a focus on cutting government red tape, reforming the tax and financial sector, as well as reforming state-owned enterprises and assets, Li said.
