Washington 'showing anxiety in stance adopted toward Beijing'

The United States has undergone several changes of mood in its attitude toward China over the past 10 years, moving from "concern" to "worry" and then to "anxiety", according to a Chinese researcher.

Fan Jishe, a US studies researcher at the Chinese Academy of Social Sciences, was reacting to comments by US Defense Secretary Ash Carter, who expressed concern over China's expanding influence.

Fan is author of the book US Military Strategy in the Post-Cold War Era - Adjustment and Adapting.
