China on Monday welcomed Brazilian President Dilma Rousseff’s pledge of big cuts in greenhouse gas emissions after 2020.

Using 2005 as the baseline level, the reduction target will be 37 percent over the next decade and 43 percent by 2030, Rousseff was quoted as saying at a United Nations sustainable development conference on Sunday.

“China welcomes Brazil’s post-2020 action plans on climate change,” Foreign Ministry spokesman Hong Lei said at a regular news briefing.

China is willing to step up communication and coordination with all parties involved, including Brazil, and in accordance with the principles of common and differentiated responsibility, equity and respective capabilities, to contribute to the success of the United Nations Climate Change Conference in Paris at the end of this year, Hong said.
