Kim arrives at venue for summit with Trump

Kim Jong-un's entourage has arrived at the luxury Singapore island resort where the North Korean leader will meet with US President Donald Trump.

Kim's black armoured limousine with two large North Korean flags was surrounded on Tuesday by police vehicles, their lights flashing, and other black cars.

There's excitement surrounding the summit but also skepticism that the North will relinquish a nuclear weapons program it spent decades building despite crushing sanctions.

Kim and Trump are scheduled to meet alone, with their interpreters, after greeting each other at the resort.

President Donald Trump arrived on Singapore's Sentosa Island for his historic meeting shortly before the North Korean leader.

Trump's motorcade pulled into the grounds of the Capella Hotel at 8.13am local time (1013 AEST).

He is scheduled to meet Kim for the first time at 1100 AEST.
