Chinese president xi jinping and us president donald trump gave duelling remarks at the virtual general assembly in new york, further ratcheting up tensions between the two nations over climate change and the pandemic.

China, the worlds biggest producer of greenhouse gases, said in a surprise move that it will cut its carbon dioxide emissions to nearly zero by 2060. the announcement will raise the pressure on the us, which is now the biggest emitter in the world that does not have a carbon-neutral target.

President trump will officially withdraw the us from the paris climate agreement in november and has refused to honour any emissions targets. in mr trumps remarks, given to the un by video, he said the us had cut its carbon emissions despite leaving the paris accord.

Mr trump also called on un members to hold beijing responsible for the coronavirus pandemic, claiming the us was engaged in a great global struggle to end what he disparagingly termed the china virus. two-hundred thousand people in the us have died, and 6.8m infections have been registered to date more than a fifth of global cases, even though the us comprises only 4 per cent of the worlds population.

Mr xi rejected mr trumps claims in his own pre-recorded speech to the un general assembly. (ft, ap)
