Brazilian President Luiz Inacio Lula da Silva has reiterated his opposition to UN Security Council sanctions against Iran.
His remarks came during meetings with Argentina's President Cristina Fernandez, following a South American trade summit. Lula said talks were needed to solve the standoff over Iran's nuclear program. And he added that all nuclear countries should disarm.
The UN imposed a fourth round of sanctions last month, after the West rejected Iran's fuel swap deal with Brazil and Turkey.
During the talks, Brazil and Argentina signed bilateral agreements, including one focusing on nuclear non-proliferation.
