The statement that comes after a brief hiatus in the war of words between Trump and Kim is likely to mar efforts towards building a denuclearised Korean Peninsula.
Washington is pressing for North Korea's complete, verifiable and irreversible denuclearisation. This comes at a time when his withdrawal from the Iran nuclear deal has drawn criticism internationally and his move of the U.S. embassy in Israel to Jerusalem has fuelled deadly violence on the Israel-Gaza border.
In the lead-up to the Singaporesummit, should it still take place, Trump may be preparing for the wrong game: a two-player round of checkers when Kim is steeling for a multiplayer two-board chess match.
"We already expressed our willingness for a denuclearised Korean peninsula and repeatedly declared that the U.S. must end its hostile DPRK policy and nuclear threats as preconditions", the deputy foreign minister said. This is State Department spokesperson Heather Nauert.
"If the United States is trying to drive us into a corner to force our unilateral nuclear abandonment, we will no longer be interested in such dialogue and can not but reconsider our proceeding to the D.P.R.K. -U.S. summit", the statement from Kim Kye-kwan read.
"We'll have to see", Mr Trump told reporters in the Oval Office when asked if the summit was still on.
"Kim Jong-un had said previously that he understands the need and the utility of the United States and the Republic of Korea continuing in its joint exercises". These are things that we do all around the world with many of our partners and allies.
Ri, head of the North's Committee for the Peaceful Reunification of the Country, described the South's reaction to the meeting's cancellation as a "confrontation racket", according to KCNA. "I actually think it's par for the course at this stage of any negotiations".
But by raising expectations about the meeting, and characterizing it as reflective of his superior deal-making skills, Trump has put himself in a position where he might need the summit to happen more than Kim does.
While the U.S.is not known to have received any notification of a change in that schedule, the KCNAreport warned Washington to "undertake careful deliberations about the fate of the planned North Korea-U.S. summit in light of this provocative military ruckus jointly conducted with the South Korean authorities".
The military drills called "Max Thunder" are taking place between the United States and South Korea air forces.
North Korea has started the process of dismantling the only known site for testing nuclear.
South Korea on Thursday urged North Korea to fulfill the agreements reached during the inter-Korean summit and to resume talks a day after Pyongyang cancelled a high-level meeting with Seoul and said it was reconsidering its participation in the upcoming summit with the US.
"We can not but take a step of suspending the North-South high-level talks scheduled on May 16 under the prevailing seriously terrible situation", the KCNA said.
