HANOI, Feb. 28 (Xinhua) -- A gap remained between what the Democratic People's Republic of Korea (DPRK) wanted and what the United States wanted, U.S. President Donald Trump said at a press conference here on Thursday, explaining the no-deal end to his second summit with the DPRK's top leader Kim Jong Un.

Trump and Kim started the two-day summit Wednesday night with a brief one-on-one chat and a dinner and continued their discussions the following day on concrete ways for peace and denuclearization of the Korean Peninsula.

The two leaders were originally scheduled to share events -- a working lunch and a signing ceremony for a possible joint statement -- at the Sofitel Legend Metropole Hotel in Hanoi, but the events were cancelled with no agreement reached, according to the White House.

After coming back to the J. W. Marriot Hotel, Trump told the press conference that Kim had a certain vision which was not exactly the same as his, though their visions got "much closer" than they were a year ago.

"We have to walk... There is a gap," Trump said.

There are no comments available from the DPRK for now.
