The International and Security Affairs Centre (ISAC) is an independent, non-profit, non-partisan and non-governmental think tank, registered as a fund and based in Belgrade.
ISAC is dedicated to the mission of promoting European Union (EU) and Euro-Atlantic integration of Serbia, rethinking new Serbian foreign policy, endorsing regional cooperation in South East Europe and examining a broad set of international and security issues.
ISAC continues, broadens and advances the work of the Defence and Security Studies Centre, established in August 2002 (within the G17 Institute), from which it evolved in January 2006 at the same time expanding its areas of interest.
