US Treasury Secretary Janet Yellen has called on China to work with Washington to fight the “existential threat” of climate change.

Speaking on Saturday, she said the two countries – the largest greenhouse gas emitters – had a joint responsibility to lead the way on climate action.

She called on China to support the US-led Green Climate Fund.

Ms Yellen is on a four-day trip to Beijing in an attempt to boost relations between the two countries.
