The general manager of Beijing Capital Group, one of the city government's most powerful companies, faces questioning over the corruption scandal that has already seen Beijing's vice-mayor removed from office. As head of Capital Land, Liu Xiaoguang ï¿½ who has not been charged with any offence ï¿½ was in charge of China's sixth-largest real estate developer and also had responsibility for numerous construction, financial services and water treatment projects. Disgraced vice-mayor Liu Zhihua was in charge of construction for the 2008 Olympics and the investigation is likely to focus on a piece of land next to Olympics venues, the Financial Times reported. The 39,000 square-kilometer site, which is set to include an office block, a hotel and apartments, was due to be developed by a joint venture including US firm AC Morgan Investment. However, earlier this month, Beijing Capital said it would be taking over the site.
