North Korea's state media has yet to report on leader Kim Jong Un's arrival in Singapore on Sunday (June 10) for his historic meeting with US President Donald Trump on Tuesday.

As of late Sunday, the latest report on Mr Kim seen on the website of the Korean Central News Agency and Rodong Sinmun, the official newspaper of the ruling Workers' Party, is the 34-year-old leader's visit to a new seafood restaurant in Pyongyang on Saturday.

North Korean media was likewise silent on Mr Kim's invitation to meet Mr Trump back in March, or to South Korean President Moon Jae In to discuss the future of Pyongyang's nuclear weapons programme.

Observers told Reuters at that time that the North Korean leadership could have withheld the news from the media "until they know for sure the summits are happening".

"There has to be an agreement within the North's inner circle about this. There's no reason why it should promise denuclearisation of North Korea to its people right now when there is a possibility of things falling apart," Reuters cited Professor Shin Beom Chulat the Korea National Diplomatic Academy in Seoul as saying.
