Multi Track Diplomacy

The theory that tracks other than the government-to-government track are important to international relations. Seems kind of obvious once you think of it. Other tracks include citizens, businesses, conflict resolution professionals, media, religions, activists, academia, and funding communities. The idea is promoted in diplomatic circles and put into action by the Institute for Multi-Track Diplomacy: http://www.imtd.org/

Of course it is also inherent in many many other organizations' work.
