China's National Audit Office (NAO) is to turn its attention to promoting the efficient use of public funds, having laid the foundations for tackling official corruption, auditor-general Li Jinhua said. By 2010, Li wants his office to spend 50% of its time eradicating the waste of government money, up from 30% now. The amount of time committed to tackling legal violations and criminal offenses will consequently fall from its current figure of 70%, the Wall Street Journal reported. The NAO has been praised for its work against corruption, publishing damning reports on the country's state banks. Li would like all his office's reports to be made public bar those containing national secrets or those that could undermine social stability. Last year, 30,205 government officials were prosecuted for graft or bribery, down from 35,031 in 2004, according to government statistics.
