Beijing  - Chinese President Hu Jintao and US President Barack Obama on Wednesday promised to work for the success of upcoming global talks on climate change.

The planned meeting of global leaders in Copenhagen in December will be "an important conference for international society to respond to climate change," state media quoted Hu as saying during talks with Obama by telephone.

The United States was "willing to work with all parties to push the (Copenhagen) meeting to produce results," the semi-official China News Service quoted Obama as telling Hu.

"The United States and China have both taken key measures to respond to climate change," Obama said.

"Both sides should make joint efforts to push the Copenhagen meeting to take concrete and meaningful steps to respond to climate change, and to make the conference successful," he told Hu.

International leaders plan to meet in Copenhagen December 7-18 to try to reach an agreement that would replace the Kyoto Protocol and regulate carbon emissions, which affect global climates. The current protocol expires in 2012.

Hu said adhering to the principle of "common but differentiated responsibilities" for developed and developing nations was in line with the "common interests of all relevant parties including China and United States."

"There are still many issues to be resolved in the current negotiations, but all parties can join hands and make efforts," Hu was quoted as saying.

"The key is to embody the fundamental principle of the UN Framework Convention on Climate Change and the Kyoto Protocol, and to solidify the achievements from the Bali Roadmap negotiations," he said.

China and other developing nations have long argued that developed countries have generated the largest amounts of greenhouse gases and should bear a greater burden in reducing them, while allowing developing nations to use economic development to raise their standards of living and reduce poverty.

Earlier this month, the leaders of China, Japan and South Korea also agreed to cooperate to ensure the success of the Copenhagen summit.(dpa)
