Trump said soon after his summit with Kim that North Korea no longer posed nuclear threats, but Pyongyang North has offered no details on its plan to denuclearize and subsequent talks have not gone smoothly.
The president made the claim during a long defence of his trade war with China.
"We will make our best efforts to ensure that we can craft practical measures to reduce military tensions and build trust between the two Koreas through this meeting", Major Gen. Kim Do-gyun, the chief of the five-member South Korean delegation, told reporters before departing for Panmunjom.
"No tests. No rockets flying. We'll see what happens".

The United States has tried multiple times over the years to negotiate the return of the remains of those killed in North Korea during the Korean War while fighting on behalf of the United Nations Command. It remains unclear whether the boxes provided on July 27 include all of the bones North Korea has accumulated over the years.
About 7,700 US soldiers are listed as missing from the Korean War, and 5,300 of the remains are believed to still be in North Korea.
Citing unnamed officials familiar with the intelligence, the United States daily said that newly obtained evidence, including satellite photos taken in recent weeks, suggests that North Koreans were working on at least one and possibly two liquid-fueled ICBMs at a large research facility in Sanumdong on the outskirts of Pyongyang. Well, it might not have been as good as Trump claimed.
"There's nothing like talking", he said. The source previously told CNN that if a peace treaty to replace the armistice agreement that ended the Korean War did not ensure the survival of the current North Korean regime, it could be the end of denuclearization talks.

This factory has already produced two of North Korea's ICBMs, including the one that could supposedly strike the US East Coast - the Hwasong-15.
Pompeo told the Senate panel that at the Singapore summit, tearing down the missile engine test site was something that "wasn't in the written agreement itself, but Chairman Kim committed in his conversation with President Trump to do". "But then they'll say, 'The next ones, we need to find them, locate them, restore them.' And then they'll start charging".
But even if he does, Sung-Yoon Lee, a Korea expert at the Fletcher School of Law and Diplomacy at Tufts University, was sceptical that there would be any fresh signs of progress when it came to denuclearisation.
