The three countries of Japan, China, and Korea face many security challenges. This project aims to identify perception gaps between the three countries by conducting attitude surveys of security experts using the Delphi Method and to find ways to promote security cooperation in Northeast Asia. This year, two surveys were conducted among 90 policymakers and researchers in the three countries. The first survey was conducted September 2006. However, given the potential for significant shifts in the experts' opinions following the nuclear test statement made by North Korea in October, a second survey was conducted in December 2006. The results and the analysis of the survey were presented at an international workshop held in February 2007 in Seoul, which was attended by 30 experts from the three countries. The results are expected to be reflected in surveys conducted next year. Under the self-operated component of this project, Seigakuin University General Research Institute was commissioned to handle administrative tasks assisting Japanese core-group members in conducting surveys and coordinating the meeting held in Japan.
