BEIJING - Sinovel Wind Group Co Ltd, one of China's largest wind turbine manufacturers, said on Monday that it is under investigation by securities regulators.

The Beijing-based company is being investigated by China Securities Regulatory Commission (CSRC) for suspected violations of securities laws and regulations, it said in a statement to the Shanghai Stock Exchange.

It gave no further details of the investigation or the allegations it faces. "The company will actively cooperate with the CSRC's investigation," Sinovel said in the statement.
