Communist Party member Zhou Shaolu, who just resigned as chairman of Shenzhen-listed Yunnan Copper, is being investigated by the party for siphoning 150 million yuan from the firm, according to Hong Kong-based self-styled civil rights news provider, the Information Centre for Human Rights & Democracy. The 57-year-old Mr Zhou has been under investigation by the party's Discipline Inspection Commission of Yunnan province since January 14, said the centre in a release faxed to the media yesterday. 'Preliminary investigation' found Mr Zhou illegally taking 150 million yuan from the listed firm 'to help one of his relatives invest in property', the release said. Of the amount, 110 million yuan has been missing since November last year. The centre also alleged he was 'having an affair' with a woman working in another listed firm in Yunnan. Earlier this week, Yunnan Copper filed a statement with the Shenzhen Stock Exchange accepting Mr Zhou's resignation 'for personal reasons' and recommending vice-chairman Liu Caiming for the top post. The centre said Mr Zhou was the first party member to be investigated since the 17th Congress of the Chinese Communist Party in October, when an anti-corruption campaign was among key issues on the agenda. A Yunnan Copper spokesman declined to comment. The Discipline Inspection Commission said it would welcome any information on the case from all sources.
