The meeting will take place in Hanoi city.

"Very productive talks yesterday with China on Trade. Will continue today! I will be leaving for Hanoi, Vietnam, early tomorrow for a Summit with Kim Jong Un of North Korea, where we both expect a continuation of the progress made at first Summit in Singapore. Denuclearization?," Trump tweeted.

Trump said he shares 'good relationship' with Kim.

"President Xi of China has been very helpful in his support of my meeting with Kim Jong Un. The last thing China wants are large scale nuclear weapons right next door. Sanctions placed on the border by China and Russia have been very helpful. Great relationship with Chairman Kim!," he said.

Trump said Kim might have realised that without nuclear weapons his nation can be one of the greatest economic powers in the world.

"Chairman Kim realizes, perhaps better than anyone else, that without nuclear weapons, his country could fast become one of the great economic powers anywhere in the World. Because of its location and people (and him), it has more potential for rapid growth than any other nation!," Trump said.

As per media reports, Kim left for Hanoi on Saturday.

Kim and Trump met in Singapore last year in June.

The latest scheduled meeting will take place on Feb 27-28.
