"I am seeing little being done by the rich countries in the help they are supposed to give," Lula said on his weekly radio broadcast.
Brazil, one of the BRIC countries (Brazil, Russia, India and China) has argued that the G8 group of industrial nations and the main developing economies is "outdated" and does not represent today's world. A more suitable forum to address the global financial crisis could be the G20, Lula has repeated.
"The big forum for economic questions should be the G20," said Lula. "The truth is that the situation is so complicated that today it is very difficult for the rich countries to take a position that does not take into account BRIC countries".
The G20 group of nations, which includes leading emerging markets, including BRIC members, agreed in London in April to triple the resources of the IMF to 750 billion US dollars to help cushion the impact on countries from the economic crisis.
The summit also set a target to more than double lending to the world's poorest countries and said additional resources for them would be raised through already agreed IMF gold sales.
"We need to demand the things we agreed that the International Monetary Fund would do and that the World Bank would do, and I think this meeting is extremely important," said Lula, who is currently visiting France.
The president of Brazil has also accused rich countries of causing the global crisis and forcing poor nations into hardship. Ahead of April's summit, he blamed "white people with blue-eyes" for irrational behavior that set off the financial crisis last year.
Italy has invited 40 nations and organizations, representing 90% of the world economy, to next week's G8 summit in a bid to make the Group of Eight more relevant as world economic power shifts to include large developing nations like Brazil, China and India.
