America tells China to stop cyber attacks
China's government must take action to stop the "unprecedented" wave of cyber attacks against America, US President Barack Obama's most senior security aide has said.
Tom Donilon, Mr Obama's national security adviser, used a speech on US relations with Asia to mount the White House's most aggressive response, so far, to a series of military-style hacks of American corporations.
Describing the problem as "a key point of concern" at "all levels of our governments", he said: "Beijing should take serious steps to investigate and put a stop to these activities."
Mr Donilon's remarks came amid mounting tensions between Washington and Beijing over a string of cyber attacks that have been linked to the Chinese military. (© Daily Telegraph, London)
