The Amazon basin countries and France Summit on climate change ended on Thursday in Manaus, Brazil, with the presence of Brazilian President Luis Inacio Lula da Silva and his French counterpart Nicholas Sarkozy, and Guyanan counterpart Bharrat Jagdeo.

In a declaration released after the end of the summit, the presidents together with representatives from Peru, Colombia, Bol via, Ecuador and Venezuela have exhorted all the developed countries, including those that have not signed the Kyoto Protocol, to present clear figures in relation to environment commitments.

"Developing countries should also contribute to face the global climate change through mitigation actions according to national conditions, supported by international funds," the statement said.

The document also brings light to the Amazon forest preservation, saying that it is "particularly sensitive and vulnerable in relation to climate change effects, which hasten our determination in facing the issue."

Earlier this month, the Brazilian president invited his counterparts of the countries straddling the Amazon basin for this meeting. France was also invited as its overseas department of French Guyana is located in the Amazon region.

Da Silva's aim was to discuss a common proposal for next month' s UN climate change conference in Copenhagen.
