Daily US Times: John Kerry, the US envoy, is heading to Shanghai to woo China in advance of a climate summit President Joe Biden is hosting next week.
After a major diplomatic row at the United Nations, both sides hope to co-operate over plans to drastically cut emissions.
Washington wants Beijing to cease building coal-fired power stations and to stop financing coal ventures abroad.
Beijing wants Washington to give more cash to developing countries to obtain clean technology and adapt to climate change.
China also wants the US to announce deep cuts in emissions.
Mr Kerry said China’s co-operation was “absolutely critical” to battle the climate crisis.
He said during an interview with CNN: “Yes, we have big disagreements with China on some key issues, absolutely. But climate has to stand alone.”
Mr Kerry is hoping to salvage the superpower relationship to allow progress at Joe Biden’s virtual summit on 22 and 23 April.
Scientists have been warning that without an agreement between the world’s great polluters there’s little chance of averting dangerous climate change.
Neither China nor the US has formally declared its climate masterplan to the UN, and each is struggling to coax more concessions from the other.
The US was absent from climate negotiations during President Donald Trump’s term in the White House and it is now being urged to cut emissions to between 57%-63% below 2005 levels this decade.
