China on Tuesday called on all countries to speed up negotiations to reach accord at the UN climate summit in Paris at the end of the year.

Foreign Ministry spokesperson Hong Lei told a daily press briefing that China appreciates France's efforts so far for hosting the summit.

"China looks forward to French President Francois Hollande's visit to China in November. Both sides are in close communication on the visit," said Hong.

China is willing to work with all parties to help the summit reach a comprehensive and balanced accord on the principle of common but differentiated responsibilities, equity and respective capabilities, Hong said.

According to China's intended nationally determined contributions (INDC), an action plan submitted to the secretariat of the UN framework convention on climate change in June, the world's largest greenhouse gas emitter aims to cut carbon dioxide emissions per unit of GDP by at least 60 percent from the 2005 level by 2030.

The latest round of negotiations on climate change concluded Friday in Bonn, Germany with progress seen by developing countries as slow, putting pressures on negotiators who will come back next month to continue thrashing out a global climate deal.

There is only one official meeting left for negotiators before they head for Paris to clinch the new climate deal which will set rules for actions to prevent global warming above 2 degrees Celsius after 2020.

"As there is not much time left before the summit, all parties need to speed up the negotiation with utmost sincerity so as to build consensus to the greatest extend," Hong said.
