摘要
Leadership is a notoriously ambiguous term in international politics,one with meanings that range from disguised hegemony or domination on the one hand to purely consensual coalition-building and the provision of focal points for collective action on the other.The term usually has positive normative content(leadership is viewed as necessary for global governance to succeed),but the form that leadership takes-the mix of instruments that are deployed,whether a single leader is necessary or collective leadership is possible-varies over time and across regions.As global leadership by the USA is called into question,the leadership norms advanced by emerging powers represent different formulas that may ultimately be transferred to the global level.Brazil in South America,Germany in Europe,India in South Asia,and China in East Asia demonstrate specific types of leadership that may coincide or clash as their roles in global governance grow in importance.
