A new report by a Chinese consortium of environmental groups has Apple in its crosshairs for alleged pollution in China.

German engineering giant Siemens has signed a memorandum of understanding with the Guangzhou Institute of Energy Conversion of the Chinese Academy of Sciences in Guangzhou to conduct a joint sustainability study on the city' s urban development.

Chinese online media Caing.com has reported that Shi Wanzhong, the general manager of human resources at China Mobile, China's largest mobile carrier, is currently under investigation for accepting bribes from Siemens.

Chinese media reports that, according to the United States Department of Justice, the German company Daimler AG has paid tens of million of dollars or given luxury sedans as bribes to officials of at least 22 countries, including China, to secure contracts.

Siemens AG says that it has signed a range of new orders worth about CNY2 billion with Chinese firms; and its environmental business accounted for a significant proportion of the total.

A new report alleging corruption in Morgan Stanley's China operations has sullied the firm's aspirations to be a good example of corporate social responsibility.

Siemens has signed a strategic partnership framework agreement with the Xianning government on the establishment of a sustainable eco-city for resource conservation.
