korea needs to do something new if it actually wants to do right by its people, my suggestion to china is that how they communicate their concerns to north korea should probably reflect the fact that the approach they've taken over the last several decades hasn't led to a fundamental shift in north korea's behavior. and the irony, of course, is that during the last 20 years, china has leapt into the 21st century, in part by abandoning some of the practices that north korea still clings to. you couldn't ask for a better model of the difference at least on the economic front, that different policies have made.
