speech at a Singapore security forum attended by Chinese military officials.

Stepping up US pressure on China over electronic espionage ahead of a summit between their leaders next week, Hagel pointedly blamed the Chinese government and military for repeated intrusions into sensitive US information systems.

“The United States has expressed our concerns about the growing threat of cyber intrusions, some of which appear to be tied to the Chinese government and military,” Hagel said in prepared remarks delivered at an annual Singapore conference known as the Shangri-La Dialogue.

“As the world’s two largest economies, the US and China have many areas of common interest and concern, and the establishment of a cyber working group is a positive step in fostering US-China dialogue on cyber,” the Pentagon chief said.
