On November 26–28, 2013, the Centre for International Governance Innovation and the Institute of Foreign Affairs and National Security hosted the fourth meeting of the Constructive Powers Initiative (CPI) in Seoul, South Korea. The workshop, Constructive Powers and Development Cooperation, considered the changing character of official development assistance and discussed the prospects of a post-2015 global development policy agenda to succeed the Millennium Development Goals. The workshop also assessed recent developments in northeast Asia’s security environment, concluding that greater sensitivity to the region’s history would go a long way to improving relations in the Korean-Japanese-Chinese triangle. This conference report concludes that CPI academics and policy makers can play an important role in streamlining a post-2015 global development agenda by: forming coalitions of like-minded groups of NGOs and governments; cooperatively conducting policy research; organizing track-two talks; and discovering potentially common interests among countries.
