For much of the past two decades, Brazil and Mexico seemed at times to be on a collision course. Diplomats from Latin America’s two largest nations were often preoccupied,if not obsessed, with a competition for an elusive role as regional leaders and players in the post-Cold War shifting global scene. The 2013 battle for the post of director general at the World Trade Organization, won by Brazilian diplomat Roberto Azevêdo over Mexican Herminio Blanco, a former trade minister, left plenty of hurt feelings. Ironically, the dispute for influence also led to convergence. The 2011 creation of the Community of Latin American and Caribbean Nations (CELAC), proposed by Mexico to affirm its Latin American identity and counter a perceived Brazilian effort to separate it from the region, was warmly embraced in Brasília as a way project leadership by promoting formats that excluded the US.
