China's top Internet security official said on Tuesday that Beijing had "mountains of data" to prove that the U.S. hacked into its systems.
According to the Chinese state news paper China Daily, China's chief security officer Huang Chongqing said that China had enough information to prove that it was a victim of U.S. cyber attacks, he also added that it would be counterproductive to blame the U.S. Government at this time.
"We have mountains of data, if we wanted to accuse the US, but it's not helpful in solving the problem," said Huang Chongqing.
"The importance of handling Internet security cases keeps rising, but the issue can only be settled through communication, not confrontation," said Huang adding that such issues can be solved only through communication, not by accusing each other.
Huang's comment comes days before the summit between the leaders of the two countries which is scheduled to be held on Thursday and Friday.
Last Sunday, Republican lawmaker Mike Rogers urged the U.S. president to be firm with his Chinese counterpart during the upcoming submit.
"China's rampant theft of American intellectual property and the jobs that come with it is holding back our economy and impacting our competitiveness around the world," said Mike Rogers. "China needs to see real consequences for their actions."
In recent months, U.S. has accused the Chinese government of hacking and stealing confidential information from U.S. military and business firms.
However, China has constantly denied the accusations saying China itself is a victim of foreign cyber attacks.
Cyber security issues in recent months appear to be one of main fractions in the relationship between the two countries.
