China, the world's worst polluter, has pledged to become carbon neutral by 2060.

President Xi Jinping, in a virtual speech at the United Nations General Assembly, made the announcement after insisting it would hit a peak in carbon dioxide emissions before 2030.

It marks the first time China has said it will end its net contribution to climate change.

In the landmark speech, Mr Xi also called on countries to pursue a "green recovery" post-coronavirus and said China would "adopt more vigorous policies and measures".
