Many of the digital attacks and cyber-snooping on U.S. technology firms and government agencies including the Pentagon, are believed to have been originated in or routed through
China, which makes Sino-American talks difficult.

Analysts say China's People's Liberation Army believes its ability to attack U.S. cyber infrastructure compensates for its conventional military weakness compared to the United States.
