President Donald Trump flew in aboard Air Force One, a few hours after Mr Kim touched down with his entourage this morning.
Their meeting – the first between a leader from the North and a sitting US president – will take place on Tuesday on the resort island of Sentosa.
Trump has described it as a “one-time shot” at peace and said the two were in “unknown territory”.
The US hopes the summit will kick-start a process that eventually sees Mr Kim give up nuclear weapons.
