US-China talks a 'step forward' in relations, says Janet Yellen

US Treasury Secretary Janet Yellen has said her visit to Beijing has marked a "step forward" in efforts to stabilise relations between the two countries.

Ms Yellen spoke at the end of a four-day trip, during which talks were held over issues including climate change.

She described the talks as "direct, substantive and productive" and said both sides had learned more about each other.

However, she admitted the US and China still had "significant disagreements".
