Different Paths and Divergent Policies in the UN Security System: Brazil and Mexico in Comparative Perspective

摘要

How can we explain foreign policy variation among UN member states? Brazil and Mexico are the most likely cases for international primacy in the UN system, given their territorial dimension, demographic tendencies, economic importance, geopolitical location and relative weight in Latin America. Yet, despite their structural similarities, their policies and behaviour in the UN system have varied, both in terms of engagement with the Security Council and commitment regarding peacekeeping. By comparing two of Latin America's most influential countries, this study identifies the underlying conditions and mechanisms that explain their differences in behaviour and policy in the UN. In particular, this article analyses and contrasts how geopolitics and civil-military relations in Brazil and Mexico affect their incentives to participate in international organizations and their overall international commitment to peace.
