Presidents Xi Jinping and Barack Obama on Saturday agreed to work closely to address climate change and reduce the production and consumption of hydrofluorocarbons (HFCs), said Chinese State Councilor Yang Jiechi.

The consensus was reached at the two leaders' second meeting at Sunnylands estate, California, Yang told reporters.

The two sides agreed to bolster coordination and pragmatic cooperation on climate change via the bilateral working group on the issue.

They also vowed to work with other nations via multilateral mechanisms, including using expertise and institutions of the Montreal Protocol, to gradually reduce the production and consumption of HFCs and continue to include HFCs within the boundary of the related emission reports and calculation clauses of the Kyoto Protocol and the UN Framework Convention on Climate Change.

Before heading into the meeting, the two leaders took a walk at the picturesque Sunnylands, a 200-acre (81-hectare) Annenberg estate in Rancho Mirage, California.

The two presidents held their first meeting and had a working dinner Friday, exchanging views on international and regional issues of common concern.
