BARCELONA, Nov. 2 (Xinhua) -- A top Sudanese negotiator in UN climate change talks on Monday warned against dismantling the Kyoto Protocol, the existing binding deal on climate change, at the latest round of UN talks.

"The killing of the Kyoto Protocol would have the effect of undermining the foundational principles of equity, common but differentiated responsibilities and respective capabilities and ultimately puts at risk any ambitious outcome to aggressively address climate change in Copenhagen," said Ibrahim Mirghani Ibrahim, head of the Sudanese delegation.

He stressed that the Kyoto Protocol must continue to form the legal basis for emission reduction commitments beyond 2012.

He added that the Group of 77 was ready to stand against all attempts by developed countries to dismantle the Kyoto Protocol, which is "the only instrument we have for developed countries to take the lead in cutting their increasing emissions."

At the last round of UN talks in September in Bangkok, some countries indicated a willingness to move away from the Kyoto Protocol, which sets binding targets for industrialized nations tocut greenhouse gas emissions before 2012.
