US and East Asian security under the Obama presidency: A Japanese perspective

The most important factor determining the structure of East Asia will continue to be the strategic relationship between the USA and China.

Japan is obviously a lesser strategic player, which is in a position to encourage middle-power security cooperation among the East Asian countries breathing between the USA and China. There is a conceptual, if not geopolitical, competition between Japan and China over an ideal future of East Asian regionalism, which the East Asian countries and the USA should join in a constructive manner.
