The second summit between North Korean leader Kim Jong Un and U.S. President Donald Trump in Hanoi, Vietnam, has ended without an agreement between the two sides.

Both leaders on Feb. 28 canceled their planned luncheon at the summit venue of the Sofitel Legend Metropole hotel. They returned to their hotels without signing a joint agreement.

Trump later held a news conference at 2:15 p.m. at the JW Marriott Hotel in Hanoi. 

On the failure to reach an agreement, the American president said, "They (North Korea) wanted the sanctions lifted in their entirety, and we couldn't do that."

"They were willing to denuke a large portion of the areas that we wanted, but we couldn't give up all of the sanctions for that."

Trump spoke highly of Kim, saying, "I think our relationship is very strong" and "It was very productive two days."

"At this time we had some options, and at this time we decided not to do any of the options."

Describing the summit mood as "very friendly," he said, "And I think frankly we'll be good friends with Chairman Kim and North Korea, and I think they have tremendous potential," hinting at the possibility of another summit.

The Hanoi summit was their second, with their first being held in Singapore last year on June 12. 

On Feb. 27, Kim and Trump had a private meeting and then dinner. The next day, both leaders began at 8:55 a.m. an exclusive and extended summit to discuss more concrete details of complete denuclearization by the North, forging a new relationship between Pyeongyang and Washington, and establishing a peace regime on the Korean Peninsula, points that had been agreed on in last year's summit. 

But both sides eventually failed to reach an agreement.
