Iran-Brazil relations, which are characterized by economic and diplomatic cooperation, are quite friendly. Iran has a productive trade balance with Brazil. The two governments signed a document to bolster cooperation during the G-15 Summit in Tehran in 2010. However, since the election of Brazilian president, Dilma Rousseff, relations between the two countries recently have deteriorated greatly, following Dilma shifting Brazil away from Iran due to Iran's violation of human and civil rights. Ahmadinejad's media adviser, Ali Akbar Javanfekr, was quoted as stating that Rousseff had "destroyed years of good relations" between them. He denied making such a statement.
