(Beijing) -- Wei Wenyuan's sudden resignation stunned his colleagues at Sinovel Wind Group but started making sense two weeks later when securities regulators announced a financial fraud investigation targeting the company.

Wei's departure May 13 after just two months as chairman and eight months as acting president also mirrored the turbulent atmosphere at Sinovel, one of China's largest wind turbine manufacturers as well as a developer of wind farms locally and overseas.
