A top aide to the North Korean leader has arrived in Singapore in the latest indication that the on‑again‑off‑again summit with US president Donald Trump is going ahead.

Kim Jong‑un's de facto chief of staff Kim Chang Son flew to Singapore via Beijing and at the same time, a team of US government officials left US Yokota Air Base in Japan for Singapore yesterday.

The White House said a "pre‑advance" team was travelling to Singapore to meet with North Koreans.

The reports indicate that planning for the historic summit, initially scheduled for 12 of next month, is moving ahead after Trump called it off last week.

A day later, Trump said he had reconsidered, and officials from both countries were meeting to work out details.
