The cancellation is seen as a significant concession to North Korea.
Although human rights was not included in the joint statement signed by Trump and Kim, the United States president said he raised the issue and he believed the North Korean leader wanted to "do the right thing". "No more rocket launches, nuclear testing or research!" he also tweeted.
For good measure, Trump again called Xi a close friend and thanked him for China's role in strengthening sanctions against North Korea. The statement made clear that Pyongyang was expecting USA concessions before any moves by the North.
Trump agreed to end joint U.S.
Earlier, South Korea's Presidential Blue House said it needed "to find out the precise meaning or intentions" of Mr Trump's statement. -North Korea relations, and to recover the remains of prisoners of war and military members missing in action.
There was little else mention of denuclearization of North Korea in the statement, which mainly focused on stopping hostilities between North Korea and the United States.
