"The United States traditionally has enjoyed robust economic and political relations with Brazil, which is the fifth most populous country and ninth-largest economy in the world. Brazil is recognized by the Obama Administration as a 'major global player' and an 'indispensable partner' on issues ranging from international development to climate change. Administration officials have often highlighted Brazil's status as a multicultural democracy, referring to the country as a natural partner that shares values and goals with the United States. Bilateral ties have been strained from time to time as the countries' occasionally divergent national interests and independent foreign policies have led to disagreements. U.S.-Brazilian relations were particularly strained following revelations in 2013 of alleged National Security Agency (NSA) activities inside Brazil. Cooperation has improved over the past year and a half, however, culminating in a June 2015 presidential meeting at the White House. Brazil and the United States are currently working together to address an outbreak of the Zika virus in Brazil and other Western Hemisphere nations. Other ongoing areas of engagement include trade, energy, security, racial equality, and the environment."
