The party's anti-corruption commission said in a one-sentence statement on its website today that Hubei province's vice-governor Guo Youming is being investigated for "suspected serious disciplinary violations."

Guo's official profile on the Hubei government website says he was in charge of the province's land and resources management and a project to divert water from China's flood-prone south to its arid north, among other responsibilities.
