KAREN PERCY: A rare insight today into a touchy subject in a notoriously secret nation: corruption in China. Official sources say that more than 40 officers in one of China’s poorest provinces, have been implicated in a billion-dollar corruption scandal.

China’s Xinhua newsagency says that an official audit in the northern western province of Gansu found that large amounts of state money, meant for infrastructure projects and public compensation, has been diverted or embezzled.

It’s the latest in a string of corruption cases this year, many of which have been made public.
