U.S. President Barrack Obama's national Security Adviser Tom Donilon called upon the Beijing government to end cyber attacks and respect the copy rights of the foreign assets.

Donilon's demand comes just a day after a Chinese security watchdog attacked the United States saying most of the sources of their hackers were from the states.
Making the first public confrontation with the Beijing government over the cyber security, Tom Donilon urged the Chinese government to consider the urgency of the issue and begin dialogues to establish global standards.

The U.S. national security adviser said that an escalating number of U.S. business organisations were complaining about the cyber theft from China.
"Increasingly, U.S. businesses are speaking out about their serious concerns about sophisticated, targeted theft of confidential business information and proprietary technologies through cyber intrusions emanating from China on an unprecedented scale," said Tom Donilon.

"The international community," said he "cannot tolerate such activity from any country."

During his State of the Union address in February, the U.S. president said that foreign countries and companies were swiping U.S. corporate secrets.

Chinese government on the other hand has repeatedly said that they were the victims of the cyber attacks and not the perpetrators.

"Anyone who tries to fabricate or piece together a sensational story to serve a political motive will not be able to blacken the name of others nor whitewash themselves," said the Chinese Foreign Minister Yang Jiechi at the latest National People's Congress meeting.

Three weeks ago, a U.S. cyber security watchdog, Mandiant came up with a 60-page study criticizing the Beijing military department for being behind the cyber attacks.

U.S. is apparently in a delicate situation balancing the words of war over the cyber espionage and seeking Beijing's support to tackle the North Korea nuclear issue.
