China on Thursday refuted the U.S. accusation of Chinese companies for stealing its Hi-tech as "groundless", saying such accusation is unacceptable to China.

Chinese Foreign Ministry spokesman Qin Gang made the remarks at a regular press conference when asked to comment on an accusation by the FBI (Federal Bureau of Investigation) criticizing Chinese companies for stealing advanced technologies in the United States through various means.

Qin said he was "astonished" at this accusation, saying someone who always regards others as a threat or even thieves is actually harboring a "fragile" psychology.

Qin pointed out that the cooperation between China and other countries, including that with the United States, is based on mutual benefit and win-win principle, adding that the Chinese companies conduct their business in the United States in compliance with local laws.
