China’s chief climate negotiator on Nov 19 unveiled the country’s position on the Paris climate change conference, saying China hopes that “a powerful, ambitious and legally binding deal” can be reached in Paris.

Xie Zhenhua, China’s special representative on climate change, made the remarks at a press conference where he released a report on China’s efforts to cope with climate change.

Xie added that a 2015 deal should reflect the principles of “common but differentiated responsibilities” and “respective capabilities.”

The Paris climate change conference, due to begin at the end of November, is the latest attempt by world leaders to reduce carbon emissions, considered by many to be the main reason behind extreme weather and the rising number of natural disasters.

In the run-up to the conference, major differences remain. Xie said developed nations still have much to do to in their pledges to provide money and transfer low-carbon and environmental friendly technology to developing countries.

“Each country should deliver what they have promised, which is the basic foundation of political trust,” said Xie, adding that mutual trust is a prerequisite for a successful conference.

He also reiterated China’s goals in its own “Intended Nationally Determined Contribution” (INDC) — China will cut its carbon emissions per unit of GDP by 60-65 percent from 2005 levels by 2030, aiming to increase non-fossil fuel sources in primary energy consumption to about 20 percent and peak its carbon emissions by the same date.

“China will ensure that the INDC targets will be accomplished in whatever circumstances. The Chinese government and the Chinese people will abide by our promises,” said Xie.
