Noting that President Barack Obama is "troubled" by cyber attacks on Google, a senior Obama administration official has said a "blanket denial" by China on the issue will not be helpful and the US was looking for an explanation from the Chinese authorities on it.
"We seek an explanation from China. We are trying to ascertain facts. The Chinese have denied that anything has happened. I think the Google statement speaks for itself. We seek an explanation from China about what did happen. A blanket denial - that nothing happened - we don't think is particularly helpful," said P J Crowley, Assistant Secretary of State for Public Affairs.
The State Department said it has had talks with the Chinese Ambassador in Washington regarding Clinton's speech, the issue of Google and broader aspects of US-China relationship.
"I would anticipate that we will have ongoing meetings both here in Washington and in Beijing on all of these subjects," he said.
Crowley said the State Department has expressed serious concerns on Google's allegation that people's emails were being breached by the Chinese.
We have serious concerns that someone in China has targeted human-rights activists; hacked into, and had an impact in terms of the commercial relationship between Google and China, he added.
