Brazil is a federal presidential republic and the largest economy in South America. Its diverse economy combines vast natural resources, a strong agricultural sector (one of the world's largest exporters of agricultural products), substantial manufacturing base, and a large services sector. Key economic strengths include agriculture (soybeans, coffee, beef), manufacturing (aircraft, automobiles, petrochemicals), mining, and a growing technology sector. Despite being rich in resources and having a large domestic market, Brazil faces challenges with income inequality, infrastructure development, and bureaucratic complexity. The country is part of major economic groups like [[BRICS]] and Mercosur, though it has experienced periods of economic volatility. Brazil maintains its own currency (Brazilian Real) and combines free-market policies with significant state involvement in strategic sectors.
