<P> Despite tense relations, North Korea agreed to participate in the 2018 Winter Olympics in Pyeongchang, and enter with South Korea during the opening ceremony as a unified Korea, and field a unified team in women's ice hockey . Following the Olympics, Kim Jong - un and President Moon Jae - in conducted the April 2018 inter-Korean summit . It was the first time since the end of the Korean War in 1953 that a North Korean leader entered the South's territory . On 12 June 2018, Kim Jong - un and US President Donald Trump met for the 2018 North Korea--United States summit in Singapore, the first - ever talks held between a North Korean leader and a sitting US President, to discuss the North Korean nuclear program . </P> <P> Scarce information on Kim Jong - un's early life comes from North Korean defectors and people who have claimed to witness him abroad, such as during his school attendance in Switzerland . Some of the information has been conflicting and contradictory, perhaps confusing him with his brother, Kim Jong - chul, who also attended school in Switzerland around the same time . </P> <P> North Korean authorities and state - run media have stated that Kim's birthdate was 8 January 1982, but South Korean intelligence officials believe the actual date is a year later . It is thought that Kim's official birth year was changed for symbolic reasons; 1982 marks 70 years after the birth of his grandfather, Kim Il - sung, and 40 years after the official birth of his father Kim Jong - il . The US Treasury Department lists Kim Jong - un's official birthdate as 8 January 1984 . Former basketball star Dennis Rodman said that this was Kim's birthdate after meeting in September 2013 in North Korea . </P> <P> Kim Jong - Un was the second of three children Ko Yong - hui bore to Kim Jong - il; his elder brother Kim Jong - chul was born in 1981, while his younger sister, Kim Yo - jong, is believed to have been born in 1987 . </P>
