'Rice urged China to join the U.S. in promoting responsible forms of state behaviour in cyberspace. She said it would be a "critical factor" in determining trajectory of US-China ties.
'"This isn't a mild irritation; it's an economic and national security concern to the United States. It puts enormous strain on our bilateral relationship," Rice said.
'Hacking attacks on U.S. companies and government agencies have become a growing source of tension ahead of the visit by Xi, who will meet Obama on Friday.
'"We want a business climate where intellectual property rights and trade secrets are respected, not stolen," Rice said.'
