LONDON - British Prime Minister Gordon Brown and Brazilian President Luiz Inacio Lula da Silva have met for talks on climate change, the Group of 20's role in global financial reform, and Olympic co-operation.

Brown's office said Wednesday that the pair discussed the upcoming U.N. climate change conference in Copenhagen. Silva has lobbied for rich countries like Britain to put up substantial sums of money to help poorer countries strike a deal on curbing global greenhouse gas emissions at the December conference.

Brown and Silva also discussed the world economic situation and how Britain and Brazil could share know-how ahead of the Olympic Games. London hosts the Games in 2012 and Rio de Janeiro four years later.
