Chinese Premier Li Keqiang and other leaders on Wednesday vowed to fully implement the "Four Comprehensives" strategic layout in order to realise 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, state-run Xinhua news agency reported.

In accordance with the "Four Comprehensives", China should make greater effort to stabilise growth, expand effective demand and withstand downward pressure, in an effort to keep economic operation within a proper range, Premier Li 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.

Li promised to inject vigour into the market by promoting mass entrepreneurship and innovation. He also stressed economic restructuring by offering more public goods and services to the people and boosting consumption relating to information and tourism.

The premier also emphasised green, safe, and efficient development of the agricultural sector.

Zhang Dejiang, chairman of the Standing Committee of the National People's Congress, joined discussion with political advisors from Hong Kong and Macao special administrative regions (SARs).

Zhang called for a full and accurate understanding of the principle of "one country, two systems" and the safeguarding of the authority of the Constitution and the Basic Law.

Zhang said the central government would fully support the law-based governance of Hong Kong and Macao SAR chief executives and the SAR governments.
