BEIJING, June 5 (Xinhua) -- China's top anti-graft official Friday said Party and government departments should reform their systems to uproot corruption.

    He Guoqiang, secretary of the Communist Party of China (CPC) Central Commission for Discipline Inspection (CCDI), listed five main sectors that reported serious corruption problems: construction contracts, real estate development, land and mining management, financial business and law enforcement.

    He told a meeting of discipline departments to push the government to reform management of these five sectors and improve supervision on them, instead of simply tightening penalties on corrupt individuals.

    The discipline departments should also help the Party and government to reform the promotion system, procedures of administrative approval, the management of finances, taxation, investment and government procurement, as well as the restructuring of state-owned enterprises, he said.

    Through these reforms, the country would be able to prevent more corruption, he said.

    New measures to prevent corruption should solicit opinion from the public and experts, He said, adding that effective ideas could be written into regulations or laws.

    Some government and Party departments have tried to improve transparency of their work and supervision from the public.

    The Ministry of Environmental Protection opened a public hotline on Thursday. People can directly inform the ministry of complaints about pollution and appeal to it if local environment authorities fail to solve problems.

    In February, the Organization Department of the Communist Party of China (CPC) Central Committee also opened a website to receive complaints of local official malpractice in promotion.
