At the Eighteenth Party Congress, the CPC Central Committee has adopted the strategic arrangement of “Four Comprehensivenesses”. As an important part of this arrangement, the strategy of comprehensively implementing the rule of law was an important milestone in the development of the rule of law in China. Recently the Newspaper Chinese Social Sciences Today interviewed a number of prominent legal scholars and experts, including Professor Zhou Hanhua, a research fellow of CASS Law Institute, on the significance and implications of this strategy. In the interview, Professor Zhou Hanhua pointed out that the strategy of comprehensively implementing the rule of law plays an important safeguarding, supporting, standardizing and guiding role in the strategy arrangement of “Four Comprehensivenesses”. The realization of the five major development ideas of “innovation, green, harmony, openness, and sharing” and the objective of building a moderately prosperous society all need to be safeguarded with the rule of law. In recent year, China has made rapid progresses in the construction of the socialist system of law, which will further safeguard civil rights, ensure the healthy development of the socialist market economy, and promote the institutionalization of socialist democracy as well as economic, political, cultural, and social development. The Constitution has the highest authority in the country. No law or regulation may contravene the Constitution. In the process of reform and opening up, because of the pluralization of the legislative subjects, there has been a tendency of legalization of departmental interests in practice. Therefore, it is necessary to stress that the ruling the country by law means first of all ruling the country by Constitution and to solve the problem of disunity of and contradictions between laws and regulations.
