MANAUS, Brazil, Nov. 26 (Xinhua) -- The Brazilian Minister of External Relations Celso Amorim called on developed countries to present concrete target to next month's UN climate change conference in Copenhagen (COP15).

    Amorim said this to journalists before the Amazon basin and France summit on climate change on Thursday in Manaus, Brazil.

    Amorim emphasized the importance of Brazilian President Lula da Silva inviting his counterparts for this meeting, but he recalled that developing countries cannot solve by themselves the climate change problems.

    "Developed countries must present numbers," he said. Besides Lula da Silva and French President Nicholas Sarkozy, the French Guyana leader Jean-Pierre Laflaquiere also came to Manaus for the summit.

    Amorim also downplayed the fact that many leaders invited by President Lula for the Amazon basin and France Summit did not come to Manaus Thursday.

    "If Sarkozy has attended the summit, it means it is not empty," he told reporters before the meeting started.

    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.

    According to Amorim, leaders from Peru, Ecuador, Bolvia, Colombia and Venezuela had each of them a good reason for not coming to Manaus. For him, just bringing together representatives from invited countries is already an important achievement.

    "In Bolivia, Evo Morales is busy with the elections process (that takes place next week). Uribe (president of Colombia) has had an accident and so on," the minister said.

    At a press conference in Brasilia on Tuesday, the presidential spokesman Marcelo Baumbach said that the discussion in Manaus would aim basic consensus about the negotiations in Copenhagen, with emphasis on themes of reducing emissions, adaptation, finance and technology.

    The UN climate change conference in Copenhagen will be held on Dec. 7-18, at which world leaders will try to strike a deal on a successor to the carbon-capping Kyoto Protocol.
