In 2015，convergence in diversity，continuity along changes，and autonomy with fragility are three pairs of variables characterizing international relations in Latin America. The yearly international drama is not just about a variety of new developments in regional cooperation and integration either originating from intra-regional dynamics or driven by extra-regional actors，but it is also a story of the dual impact of practical interests and historical legacies upon the cooperation and conflict among Latin American countries themselves. The obvious landmarks of the year include the change in US-Latin America relations，and to a lesser extent the launch of integral cooperation between China and Latin America，showing the active roles played by great powers in the reconfiguration of the hemispheric affairs.
