Chief of Chinese delegation to the UN climate conference says the extension of the Kyoto Protocol and implementation of financial support by rich countries are of central importance for the negotiations.

Xie Zhenhua said a ratifiable and legally binding amendment of the Kyoto Protocol needs to be worked out in Doha so that the treaty can enter an extension right after its first commitment period expires at the end of 2012.

The Chinese climate official also stressed that financial support to help developing countries adapt and mitigate the effects of climate change is another important issue. He called for greater transparency about the developed countries' financial support for their developing peers.

With respect to the Durban Platform, Xie said negotiations should respect the principles of equity, "common but differentiated responsibilities," and respective capabilities. He also pledged openness and flexibility on the part of China if previous promises were upheld.
