BONN, Germany, June 7 (Xinhua) -- China's chief climate negotiator has called for enhanced political mutual trust among all parties in climate negotiations.
Political mutual trust should be boosted to set a political "foundation" for improving global climate change responses and reaching a new agreement in the regard, Xie Zhenhua said.
Xie, deputy chief of China's National Development and Reform Commission, made the remarks Friday at a ministerial meeting on climate change here.
The trust can only be built when parties fulfill their commitments and bolster actions against climate change, said the Chinese official said.
He said developed countries should play a leading role in the process of addressing climate change.
In addition to their emission reduction commitments, which should be increased further, developed countries should fulfill their obligations to provide funding, technology and capacity-building supports to developing countries, the Chinese lead negotiator said.
He urged developed countries to come up with a clear roadmap to ratchet up their financial support, with public funds as the main source, in the coming years to meet the goal of providing 100 billion U.S. dollars per year by 2020.
Xie said the global climate change agreement set to be reached in 2015 in Paris shall be based and built on the structure and rules of the United Nations Framework Convention on Climate Change (the Convention), and guided by basic principles of the Convention such as "common but differentiated responsibilities."
The new pact should consider global climate change actions, including climate change mitigation and adaptation, funding and technology transfer, in a comprehensive manner, while sticking to differentiation between developed and developing countries in their efforts, he said.
After the year 2020, developed countries should continue undertaking commitments on quantified economy-wide emission reduction targets, and fulfilling obligations of providing finance, technology and capacity-building supports to developing countries, according to the Chinese negotiator. Meanwhile, developing countries should step up their mitigation and adaptation efforts with support from developed countries.
According to plans, in the UN climate conference in Lima, Peru scheduled for later this year, elements of the 2015 global climate change agreement draft would be decided.
Describing the Lima conference a key phase in the multilateral global climate negotiations, Xie said elements of the agreement draft set to be reached there should cover all the pillars of the Convention.
The 2015 agreement, set to be reached at the Paris conference next year, should make an arrangement on principles regarding what kind of common and differentiated enhanced actions will be made by developed and developing countries, the Chinese official said.
Stressing China's unwavering resolve and efforts in working with other countries on climate change actions, he said China has set a target of cutting its carbon dioxide emission per unit gross domestic product by 40 percent to 45 percent by 2020, compared to 2005.
Meanwhile, China is working to come up with a target for its contribution to global action on climate change in the post-2020 period by the end of first half of next year, Xie said.
