Kim left his hotel by his bulletproof Mercedes-Benz limousine at around 5:03 p.m., escorted by a massive police motorcycle convoy, and arrived at the embassy just a few minutes later. 

As the car stopped in front of the main gate, he was seen disembarking and walking into the compound about 1 kilometer away from his Melia hotel. He was surrounded by a team of bodyguards dressed in black suits.

Kim reached the Vietnamese capital earlier in the day, wrapping up a nearly 70-hour train and road journey from Pyongyang.

Kim was accompanied by his sister Kim Yo-jong, a senior workers' party official, in the embassy visit.

A diplomatic source here said Kim is not going to have any other official engagements on Tuesday, as he is scheduled to start a two-day summit with Trump the following day. (Yonhap)
