The UN climate conference in Copenhagen has not produced a deal on climate change as leaders of 193 nations are beginning to arrive for a summit expected to sign a pact to fight global warming.
The nations have failed to reach an agreement on new targets for greenhouse gas emission cuts and financial aid to poor countries on efforts to curb climate change.
Negotiators worked through the night but failed to settle the differences. The main dispute was between the world's biggest polluters, the United States and China.
A representative of the WWF in Russia who is taking part in the conference as observer said the overnight talks brought a draft deal that offers no specific solutions or final targets.
"This text will now be submitted for a plenary session and if approved, will be offered to the leaders for discussion," Alexei Kokorin said.
Kokorin said separate talks on the Kyoto Protocol, which binds nearly 40 rich nations except the U.S. to limit carbon emissions, also brought a document - "an empty chart developed nations are to fill in with their commitments on greenhouse gas emission cuts."
"Both documents are not a breakthrough, but a bureaucratic move to offer some document to the heads of state," he said.
Observers have suggested the talks in the Danish capital were likely to produce a political agreement, rather than a legally binding pact to replace the Kyoto Protocol, which expires in 2012.
