Three leading global think tanks – The Centre for International Governance Innovation (CIGI), The Stanley Foundation in the United States and The China Institutes of Contemporary International Relations (CICIR) in the People’s Republic of China – joined together in 2009 to examine the many challenges facing global governance leadership in the rapidly evolving context of “messy multilateralism.” In this document a representative of each partner institution summarizes current global governance leadership challenges and the prospects for the upcoming G8 and G20 summits in Canada. Each “voice” is personal but informed by the work of the respective institutions – “three voices” from three critical countries involved in global governance: Canada, China and the United States.
