Bilateral China-US talks could set the tone for the COP28 UN climate summit in November. China's manufacturing-led economy produces the most carbon emissions and Beijing has increased its commitment to coal power.
US climate envoy John Kerry arrived in China on Sunday to restart stalled talks between the world's two biggest carbon emitters.
Kerry will meet his Chinese counterpart, Xie Zhenhua, in Beijing to focus on issues including reducing methane emissions, limiting coal use, curbing deforestation and helping low-income countries to address climate change.
Some analysts cautioned against expecting any major breakthrough, but the meetings could help ease strained ties between Washington and Beijing over a string of issues, including trade, human rights and Taiwan.
Both countries previously said they should be able to collaborate on climate change regardless of falling out over other issues.
But after the visit in August by former House of Representatives Speaker Nancy Pelosi to Taiwan, a democratically governed island that China claims as its own, Beijing said it would halt all climate-related dialogue with Washington.
