A senior German business executive is now under fire on China's social media over his insulting remarks about China.

Rainer Gartner, president and CEO at Daimler Trucks & Buses China Ltd., has made a disparaging comment on Chinese people, saying that "I have been in China one year already; the first thing I learned here is: All you Chinese are bastards."

His gaffe came after a parking row with a Chinese driver at a residential community in Beijing's northeastern Shunyi District.

The quarrel drew passersby to come and defend the Chinese, but they were pepper sprayed by the German executive.

The Chinese driver said he will seek legal actions against Gartner for his actions and remarks.

"The German executive should apologize for his wrongdoings immediately," said a microblogger on China's twitter-like Sina Weibo.

"Expats should behave themselves and never put on airs even if they are rich or superior," said another microblogger.

Another German political leader also triggered outrage for his rude remarks in October this year.

In his comments, European Commissioner Guenther Oettinger mocked a delegation of Chinese ministers, saying that their hair was combed "from left to right with shoe polish."

He also used the words "slitty eyes" and "chiselers" to refer to Chinese people.

The gaffe-prone German politician later claimed that he meant no offense when he was secretly recorded using those terms.
