From the Introduction: "As the 6th -most populous country and the 12th -largest economy in the world, Brazil plays an important role in global governance[.] Over the past 20 years, Brazil has forged coalitions with other large, developing countries to push for changes to multilateral institutions and to ensure that global agreements on issues ranging from trade to climate change adequately protect their interests. Brazil also has taken on a greater role in promoting peace and stability, contributing to U.N. peacekeeping missions and mediating conflicts in South America and further afield. Although recent domestic challenges have led Brazil to turn inward and weakened its appeal globally, the country continues to exert considerable influence on international policy issues that affect the United States. U.S. policymakers have often viewed Brazil as a natural partner in regional and global affairs, given its status as a fellow multicultural democracy. Repeated efforts to forge a close partnership have left both countries frustrated, however, as their occasionally divergent interests and policy approaches have inhibited cooperation. [...] Congress has expressed considerable interest in Brazil in recent years, recognizing Brazil's potential to affect U.S. foreign policy initiatives and interests."
