The US and China have resumed formal climate talks for the first time since they were put on ice earlier this year when the relationship became strained over Taiwan.
US President Joe Biden and China President Xi Jinping agreed to address climate change in their recent exchange in Bali, while top Chinese climate negotiator Xie Zhenhua and John Kerry, the US special presidential envoy for climate, did the same at COP27 in Egypt.
"Discussions between China and the US … [were] very candid, friendly, active and positive, and very constructive," Mr Xie said, according to Chinese state broadcaster CCTV.
