Brazil would maintain the dialogue with Iran started under Lula, Brazil's Foreign Minister Antonio Patriota said to state media, ILNA reported.
"We consider it in our interest to maintain a dialogue with the Iranian government, including as a way to reduce tensions, because isolation sometimes only exacerbates a worrying situation that could lead to a conflict," he said.
On Friday, Brazil's new president Dilma Rousseff set out its foreign policy stressing dialogue with Iran, and saying it sees itself as an agent for "world peace"
According to Patriota, the relationship with Tehran contributed to Brazil's aim of "contributing to world peace".
Lula and Iranian President Mahmoud Ahmadinejad had friendly ties, underlined when Brazil and Turkey last year extracted a concession from Tehran to engage in a nuclear fuel swap deal.
Rousseff will explore the issue of Iran further when she hosts a visit by US President Barack Obama next month, AFP reported. Her office said Obama would speak with her in Brasilia on March 19.
