Gathered in Brazil, nine nations in the Amazon region have called on rich countries to provide poorer nations with the funds to preserve forests. The nations, meeting in Manaus, Brazil, also discussed supporting a 40% reduction in global emissions by 2020.
The meeting comes shortly before the key global summit on climate change in Copenhagen, Denmark. The Amazon nations agreed on broad principles rather than concrete steps, correspondents said.
Brazilian President Luiz Inácio Lula da Silva chaired the meeting of delegates from Bolivia, Colombia, Ecuador, Guyana, Peru, Venezuela and Surinam, with French President Nicolas Sarkozy representing French Guiana.
Presidents Sarkozy and Lula da Silva said richer nations must increase their aid to help the poorer countries fight global warming.
"The poor need to be supported without any country giving up its sovereignty," President Lula said.
The BBC's Paulo Cabral reports from Manaus that for the past few days diplomats have been negotiating a common position to be presented by the Amazon countries and France at the conference in Copenhagen.
The common statement agreed in Brazil establishes broad principles rather than fresh or concrete proposals, he adds.
He says most of the presidents invited did not come to Manaus, though diplomats say that the ministers and ambassadors sent in their place were in a position to close a deal.
Brazil proposed fighting deforestation in the Amazon basin with financial backing from wealthy nations.
"Let no gringo ask us to let an Amazonian starve to death under a tree," Lula da Silva said in a speech ahead of the meeting.
"We want to preserve the forests, but other countries have to pay for that preservation."
At the summit, the Brazilian government presented its efforts to reduce destruction in the Amazon as a key part of its strategy to combat climate change.
Earlier this month, Brazil's government said the rate of deforestation in the Amazon had dropped by 45% – and was the lowest on record since monitoring began 21 years ago.
It said that just over 7,000 sq km had been destroyed between July 2008 and August 2009. Brazil is seeking an 80% reduction in the deforestation rate by 2020.
The environmental group Greenpeace has welcomed the latest drop but says there is still too much destruction in the rainforest. Earlier this month, Brazil said it aimed to cut its carbon emissions by at least 36% below 1990 levels by 2020
