The summit, the second since the two leaders met in Singapore last June, is expected to build upon their agreement to "work towards a complete denuclearization of the Korean Peninsula."
After a two-and-a-half-day trip that covered about 2,800 miles overland, Kim arrived Tuesday to a red carpet welcome at 8:15 am. Local time at the Dong Dang Railway Station in the Dong Dang border town of Vietnam's Lang Song province.
There was a heavy security presence at the station, with Vietnamese soldiers and sniffer dogs patrolling the area. Camera crews gathered outside in anticipation of the arrival.
The trip is considerably more arduous from a logistical perspective than Kim's previous meeting with Trump, during which he hired a Chinese plane to travel to Singapore.
Like most things related to North Korean leadership, Kim's exact route from Pyongyang to Hanoi has been shrouded in secrecy.
North Korean Central News Agency reported Kim's departure and said the leader was accompanied by North Korean lead negotiator in the nuclear talks Kim Yong Chol, his sister Kim Yo Jong, and various other high-ranking officials.
