US envoy John Kerry is visiting Shanghai to persuade China ahead of a climate summit.
US President Joe Biden is hosting a climate change summit next week and he has invited several countries to join.
Both China and the US hope to cooperate over plans to cut emissions.
According to the international news agency. The US wants China to ease building coal power stations. The US also wants China not to finance coal ventures abroad.
On the contrary, China wants the US to grant more money to developing countries to get clean technology. Washington has been asked to announce deep cuts in emissions as well.
US envoy John Kerry said to the international news source that China’s cooperation was “absolutely critical” to battle the climate crisis.
“Yes, we have big disagreements with China on some key issues, absolutely. But the climate has to stand alone.”
Scientists warn that there are minimum chances of averting dangerous climate change without a deal between the world’s great polluters.
Bernice Lee, a China expert at the UK think tank Chatham House, said: “This is good news. At least they’re talking in the run-up to the summit. There will be big issues for both sides to resolve. But they must be resolved.”
