The U.N. Climate Change Conference held?in Cancun?was a success and the Kyoto Protocol had been reaffirmed, the head of the Chinese delegation said Saturday.

Xie Zhenhua said the parties advanced with the guidance of the "Bali Road Map" and reached success at Cancun.

"The achievements of the conference are results of the parties' efforts and the advantages of the multilateral mechanism, which can promote the negotiation progress. We have full confidence in the multilateral mechanism after the conference," he said.

The next climate conference will be held in Durban in South Africa in 2011. According to Xie, the parties are confident about the South Africa conference. "We can step forward in South Africa, if we can continue to consolidate and carry on the spirit of unity and coordination formed at the Cancun conference," he said.

Although the results were positive, it could not be described as "perfect". Some details were left to solve in South Africa, Xie said.

"We will hold discussion about the substantial contents of the Kyoto Protocol's second commitment period at the South Africa conference. The issues, including finance, technology, forestry and adaptation, which are the focus of developing countries, should be put into practice," he said.

Xie also said the parties would try to talk about the details and establish a transparency mechanism in South Africa.

The U.N. climate change conference finally reached a deal to fight global warming early Saturday after an all-night session, overruling objections from Bolivia.
