Brazil’s emergence as major economic power gave its president the confidence to assert her views at a meeting with US president Barack Obama on Monday.
Dilma Roussef expressed concerns about US and other Western countries’ monetary policies, claiming that they lead to devalued currencies which in turn harm poorer economies.
Roussef also warned Obamba that sanctions against Iran could backfire, causing a spike in oil prices.
Nevertheless the meeting was reported to have been generally cordial, and the wish for closer relations between the two countries received a boost with the signing of an aviation accord that will promote more travel between the US and Brazil.
The deal was signed by US Secretary of State Hillary Clinton and the Brazilian Foreign Minister Antonio Patriota.
America is keen to gain greater access to an increasingly wealthy Brazilian population which now stands at 190 million people.
