The Ministry of Commerce hopes the German government's recent investigation on a cross-border acquisition by a Chinese company is "an exception" and doesn't represent its economic policy against Chinese businesses, said the ministry's spokesman on Wednesday.

Shen Danyang, the spokesman, said even though Chinese investment in Germany has grown rapidly in recent years, the total volume is still relatively small. It is unnecessary for German officials to worry that German technology and jobs will be lost as a result of Chinese investment.
