North Korean leader Kim Jong-un has arrived in Beijing for a 4-day visit, at the invitation of Chinese President Xi Jinping. Mr. Kim is accompanied by his wife Ri Sol-ju.

The visit comes amid reports that negotiations are under way for a second summit between Mr Kim and us President Donald Trump.The two met last June, the first such meeting for a sitting US President.

Speculation had grown that Mr Kim was possibly making his way to China after South Korea’s Yonhap news reported that a North Korean train had been seen crossing the border.

Dozens of security vehicles and officials blocked roads around the train station in the border town of Dandong.
