Retooling great power nonproliferation theory: Explaining China's North Korea nuclear weapons policy.

China's policy toward North Korea's nuclear weapons programme represents an empirical and theoretical puzzle. Contrary to political relationship theory, Beijing has opposed its ally North Korea acquiring nuclear weapons. And contrary to power projection theory, a favourable asymmetry in material power has not resulted in Beijing being able to persuade, or otherwise coerce Pyongyang into terminating its nuclear weapons programme. To understand China's policy on the North Korean nuclear proliferation issue, the concepts of power and power projection need to be understood differently, in relational power terms. The relational view of power calls for the specification of scope, domain, the means, and the opportunity cost of alternative policy options. Once this is done, the limits and complexities of Chinese policy come into clearer focus. [ABSTRACT FROM AUTHOR]
