UN climate chief Yvo de Boer said on Tuesday that the key to further engagement in fighting climate change by the developing nations is whether the developed countries will show leadership by committing themselves to curbing emissions.

"What is clear to me is that further engagement by developing countries...will only happen if the industrialized countries show leadership by committing (themselves) to real emission reduction. It will only happen if relevant financial and technical support mechanisms are available," de Boer told a press conference here.

Noting that the impact of climate change is going to affect the developing countries most, de Boer said new sources of funding have to be found to deal with the inevitable effects of climate change.

"How can we create institutions to the benefit of developing countries? Because without that signal of encouragement, without the signal that countries here are serious, we'll not (be able to)build the basis of trust," he said.

Citing China, India, South Africa and Mexico as models of establishing national climate change strategy among the developing world, de Boer said a lot of developing countries are already acting on climate change without the assistance of international support.

During the marathon climate talks in Poznan in central Poland in the past eight days, the developing countries and the developed countries had clashed over a number of issues like the shared vision and the adaptation fund.
