Trump-Kim summit: How might Kim Jong-un travel to Vietnam?
It's not the most conventional journey, but some reports suggest that North Korean leader Kim Jong-un could soon be making his way to Vietnam by train, for an upcoming summit with US leader Donald Trump.
If such a journey does take place, it's expected to take at least two days and could see Pyongyang's leader travel more than 3,000km (1,860 miles) kilometres to Hanoi.
But Mr Kim's travel plans often remain highly secret.
The last summit between the two leaders in Singapore was similarly shrouded in mystery. It was clear Mr Kim would have to fly in but it wasn't clear what plane he would be coming in on until the very last minute.
Similarly, it's highly likely we won't find out much about his chosen mode of transport or route until he actually arrives.
But what would such a journey look like?
Japanese and South Korean media first cited sources saying Mr Kim was likely to take his distinctive green and yellow private train from Pyongyang to cross the border town of Dandong into China and then go onwards to Vietnam.
Later sources told Reuters that Mr Kim would stop at the Vietnamese border station of Dong Dang where he would disembark and drive 170km (105mi) to Hanoi by car.
