Qatar is interested in buying minority stakes in Brazil's state-run oil giant Petrobras (PETR4.SA)(PBR.N) and Banco do Brasil (BBAS3.SA), a Brazilian cabinet official told Reuters on Wednesday.

The country's investment agency already owns a $300 million stake in Brazil's Vale (VALE5.SA)(VALE.N), the world's largest iron ore miner, said the official, who requested anonymity because the conversations were private.

Sheik Hamad bin Khalifa Al-Thani, Qatar's emir, met with Brazil's President Luiz Inacio Lula da Silva earlier on Wednesday.
