China on Thursday denied any official involvement in cyber attacks after Google alleged the nation's hackers broke into hundreds of Gmail accounts, saying that putting all the phishing blames on it is "unacceptable."

"To put all the blame on China is unacceptable. The Chinese government pay a great attention to cyber security and administer internet according to law," Foreign Ministry spokesman Hong Lei told reporters here.

"The so called statement that the Chinese government support hacker attacks is totally a fabrication out of nothing and made out of ulterior motives," he said.

Internet search giant Google on Wednesday alleged hackers based in China broke into hundreds of Gmail accounts, including those belonging to senior US government officials and military personnel.

Hong asserted that hacking is an international issue and China is also a victim. "Hacker attacks are an international issue and China is also a victim of it."

He said China administered the internet with a host of law and regulations.

The Chinese government always acted against criminal activities, including hacking and other activities that impaired internet and computer networks, Hong said. "We punish these activities according to law."
