Senior Chinese officials have denied that it is attacking servers in the United States.
Vice Foreign Minister Cui Tiankai said that while everyone is claiming that there is a cyber cold war between the US and China it is rubbish. The two countries might suffer from cyber attacks, but they were in no way directed by either government, he said.
While it is not unusual for China to deny that it carries out attacks, it is rare for it defend the US saying that it is not doing them either. Earlier this month, US Defense Secretary Robert Gates said Washington was concerned about cyber-attacks and was prepared to use force against any it considered an act of war.
However if the US did declare on war on China, its consumers would lose most of their manufactured products. It is unlikely that the US would want to anger consumers by dropping bombs on the country which makes its iPads.
