The White House has announced that US President Barack Obama asked Chinese officials to take action regarding China’s cyber activities to end tension.
China has been accused of being involved in hacking government and commercial computer systems by the United States.
Most recently, US authorities accused China of hacking into federal records of millions of US employees.
US Secretary of State John Kerry spoke in Washington, saying both the US and China would cooperate with each other to come up with a code of cyber conduct.
"There was an honest discussion, without accusations, without any finger-pointing, about the problem of cyber theft and whether or not it was sanctioned by government or whether it was hackers and individuals that the government has the ability to prosecuted,” Kerry said.
He added that the US made it “crystal clear" that this situation would not be allowable.
"We need to work through how all countries are going to behave, but particularly how we're going to work this out in terms of the bilateral relationship,” he said.
China denied all allegations of being behind a security breach at the US Office of Personnel Management (OPM).
The US must "respect the facts," said State Councillor Yang Jiechi in Washington.
Jiechi also added that they were ready to work with the US regarding cybersecurity issues.
