Brazil did not get an endorsement from the visiting US President Barack Obama for its candidacy for a permanent membership of the UN Security Council as did its G4 partner India in November 2010.
Brazil got only an "appreciation" from Obama for its aspiration.
G4 is a group of four nations - India, Brazil Japan and Germany - who have pledged to support each other's bid for a permanent seat at the UNSC.
"President Obama expressed appreciation for Brazil's aspiration to become a permanent member of the Security Council, and acknowledged its assumption of global responsibilities," said a joint statement issued by the two countries.
Obama is in Brazil for a two-day state visit, opening it with a meeting with President Dilma Rouseff on Saturday. The two discussed many issues of shared interest, including UN reforms, finding a prominent mention in the statement.
Obama endorsed India's candidacy during a high-profile visit last November surprising everyone in India and the world community in a speech to the joint session of Parliament in New Delhi.
India has won the endorsement of four of the five permanent members of the Security Council - the US, UK, France and Russia, with China holding out the promise of "let's talk about it".
Japan is the only other G4 country with an endorsement from the US, getting it in 2004. Germany stands probably the least chance - at the moment - as Europe is already over-represented in the council.
The four countries work together on many world platforms and announced they will be coordinating their decision at the UN. India, Brazil and Germany worked together to abstain in the UNstops SC vote on Libya most recently.
