Rome, Nov 17 (EFE) Brazilian President Luiz Inacio Lula da Silva said here Monday that he was 'disappointed' after US President Barack Obama and China's Hu Jintao agreed to not set targets for emissions reduction.

'I'm disappointed, but not surprised' at the agreement reached in Singapore between Obama and Hu, but 'the US and China must sooner or later propose their targets also, although it won't be at the Copenhagen Conference,' Lula told reporters after meeting in Rome with Italian Prime Minister Silvio Berlusconi.

The US and China, the world's biggest polluters, Sunday dealt a blow to the climate conference that will begin Dec 7 in Copenhagen after informing the Danish government that it will not be possible at that summit to achieve an accord that will set targets for the reduction of carbon dioxide emissions, the main factor in global warming.

Lula emphasized that he will go to Copenhagen regardless to defend Brazil's climate proposals.

Last Saturday, Lula and French President Nicolas Sarkozy noted that the final objective of the Copenhagen summit is a worldwide reduction in carbon dioxide emissions by at least 50 percent by 2050 compared to their level in 1990.

Lula is in Rome to attend the World Summit of the UN Food and Agriculture Organization.
