Chinese Premier Wen Jiabao on Thursday stressed the need to stay on the dual-track negotiation mechanism in UN climate talks when he met some world leaders attending the Copenhagen climate change conference, Vice Foreign Minister He Yafei said.

"The negotiation under the Bali Road Map has been going on for two years, (and) the two working groups have worked hard and made some progress and achieved some consensus," He quoted Wen as saying at a press briefing on the sidelines of the Copenhagen climate change conference.

The two texts produced by the chairs of the two working groups have displayed "the consensus we have reached by the parties, especially the dual-track approach that has been taken onboard," Wen added.

"This is in line with the authorization or mandate of the Bali Road Map and certainly should be the basis of our negotiations," Wen said.

Wen stressed that the decisions to be made under the UN Framework Convention on Climate Change and its Kyoto Protocol respectively should be "balanced" and "simultaneous."

If an agreement can be reached on the basis of these two documents, it will "lay a foundation for international cooperation in tackling climate change and for the negotiations we have conducted here and further negotiations we are going to do later on," he said.

Wen also told the world leaders he met that negotiators should also try to reach a consensus on emission targets, monitoring mechanisms, long-term goals, and funding in order to reach a deal on climate change.
