Brazil’s President Dilma Rousseff has stressed the growing importance of relations with the US after meeting President Obama at the White House.
Ms Rousseff said there was potential to deepen co-operation, particularly in Brazil’s booming oil and gas industry.
She expressed concern about expansionist monetary policies in developed countries, saying they were impairing growth in emerging economies.
President Obama said US-Brazil relations “had never been stronger”.
He hailed the “extraordinary progress” Brazil had made under President Rousseff and her predecessor, Luiz Inacio Lula da Silva, saying it had become “a leading voice in the world”.
President Rousseff is making her first official visit to the US.
