COPENHAGEN: Indian Prime Minister Manmohan Singh said Friday that the Copenhagen climate summit may fall short and called for talks in 2010 to complete a deal.

"The outcome may well fall short of our expectations," Singh said on the final scheduled day of the 194-nation negotiations in the Danish capital.

Singh called for "subsequent negotiations towards building a truly global and genuinely collaborative response to climate change being concluded during the year 2010."

"To settle for something that could be seen as diminished expectations and diminished implementations would be in our view a very wrong message to emerge from this conference," he said.

Singh stood by a key demand of emerging economies -- that the Kyoto Protocol, whose obligations to cut carbon emissions blamed for global warming expire at the end of 2012, remain legally in force as a treaty.

The Kyoto Protocol made no demands of developing countries, leading the United States -- the largest industrial power -- to shun it.

"It would go against international public opinion if we succumb in its replacement by a new and weaker set of commitments," Singh said.

"Each one of us gathered here today acknowledges that those most affected by climate change are the least responsible for it," Singh said.
