Business Insider reports: "North Korean Leader Kim Jong Un is in Beijing, Bloomberg News quoted three sources as saying on Monday. Chinese social media had been swamped with rumours Kim was heading to Beijing, as a train in which he is believed to have ridden reportedly caused delays across northeast China. The Kim family has a history of travelling to Beijing via train, but this would be the first known time Kim has met another head of state or left North Korea since becoming supreme leader. President Donald Trump's decision to accept a meeting with Kim may have prompted China to invite him for talks."
