A group of US officials has crossed the border from South Korea into the DPRK to prepare for the proposed summit between Donald Trump and Kim Jong Un.

The 'Washington Post' reported that Sung Kim, a former US ambassador to South Korea and ex-nuclear negotiator, is leading the US team. Meanwhile, the White House said a "pre-advance team" left for Singapore - where the summit has been expected to take place. Yonhap news agency also reported that a senior DPRK official arrived in Beijing today, and is apparently on his way to  Singapore as well. South Korean president Moon Jae-in may join for the three way summit in Singapore. Our reporter Miro Lu tells us how the island-nation is preparing for this.
