Brazilian President Luiz Inacio Lula da Silva said he would try everything to reach a solution with Iran over its nuclear program, according to a newspaper interview on Sunday.
"I want to exhaust every possibility up until the last minute of finding a pact with the president of Iran so that it can carry on enriching uranium but assuring us that it's only for peaceful purposes," he told El Pais.
Turkey and Brazil, both non-permanent members of the United Nations Security Council, have been trying to revive a stalled nuclear fuel deal in a bid to stave off further sanctions against Iran.
Lula will travel to Iran at the end of next week to work with President Mahmoud Ahmadinejad and other Iranian leaders towards a negotiated solution with Iran, Brazilian Foreign Minister Celso Amorim told Reuters on Friday.
Last week Iran voiced optimism over Brazilian mediation efforts, welcoming in principle ideas at reviving the nuclear fuel deal with major powers.
The United States last week accused Tehran of trying to buy time by accepting Brazil's offer to mediate and declared Washington would be undeterred in pushing for new UN measures against the Islamic Republic.
