A leading think tank has responded to growing US and Japan military ties and what it described as their strategy of trying to contain China.

The report, jointly written by departments of the Chinese Academy of Social Sciences, is the fifth by the nongovernment think tank the China Strategic Culture Promotion Association since 2012.

Tokyo and Washington revised their military ties in 2015 under the Guidelines for Japan-US Defense Cooperation, which revealed "the intention of a closer Japan-US alliance to contain the rise of China", the think tank said.
