China's Foreign Ministry reiterated a denial of involvement in cyber attacks on Friday.
This is after French news agency, AFP, published a report that linked recent attacks on planemaker Airbus to China.
Foreign Ministry spokesman Geng Shuang addressed the matter at a daily media briefing. He said: "China resolutely opposes any form of cyber attack". He added: "Recent reports are irresponsible, unprofessional, and have ulterior motives".
A series of cyber attacks on Airbus in the past few months was conducted via the computer systems of its suppliers and security sources suspect a link to China, AFP reported on Thursday.
An Airbus spokesman said the company was "aware of cyber events" and like any major high-tech industrial player it is a target for "malicious acts".
Airbus "continuously monitors" such threats through detection systems and can take "immediate and appropriate measures to protect itself at all times," he said.
