China and US release 'joint declaration' on climate action

The US and China have released a rare joint declaration pledging action on climate change.

The document, called "enhancing climate action in the 2020s", commits the countries to develop long-term strategies to reach net-zero.

Xie Zhenhua, China's top climate negotiator, is explaining what's in the statement at a press conference in Glasgow.

He says the declaration - agreed this afternoon - commits the two countries to "concrete measures" to achieve the Paris Agreement goals of keeping global warming below 2C and "pursuing efforts" to limit it to 1.5C by the end of the century.

"We committed to adopt enhanced climate actions in order to achieve the Paris agreement goal and strengthen its implementation," he adds.
