BEIJING - A senior North Korean official arrived in Beijing on Monday (May 28), apparently on his way to Singapore for preparatory talks leading up to a potential summit between North Korean leader Kim Jong Un and US President Donald Trump.

The official is said to be leading the country's delegation to discuss the logistics and security issues associated with the summit, sources told Yonhap News Agency.

Yonhap initially said the official is Mr Ri Son Gwon, chief of the North's agency handling inter-Korea affairs, but later amended its report to say it was unable to confirm the official's identity.

The news agency also tweeted a photo of a North Korean embassy vehicle leaving Beijing's airport.

A US team lead by White House deputy chief of staff for operations Joe Hagin is also reportedly bound for Singapore for summit-related discussions with the North Korean team.
