Editor's Note: The 19th National Congress of the Communist Party of China approved some amendments to the Party Constitution, including the Party disciplinary inspection system. Du Zhizhou, deputy director of the Clean Governance Research Center at Beihang University, explains to China Daily's Zhang Zhouxiang the importance of those amendments for society. Excerpts follow:

Q: The Party Constitution says the Party's leading committees, especially the departments and offices under the CPC Central Committee and the State Council, China's Cabinet, shall carry out inspections in response to the needs of their daily work, while city and county Party committees shall establish a discipline inspection system. What is the difference?

A: Higher-level Party committees are inspected by temporary teams whose members come from different organizations while lower-level ones are inspected by permanent teams from professional departments. That's because higher-level Party committees have more power, so the teams inspecting them should be composed of members from different backgrounds in order to avoid any possible link. In lower-level Party committees, permanent inspection teams are more effective in curbing corruption.
