Earlier on Friday, a spokeswoman for South Korea's Ministry of Unification told a press briefing that the weekly inter-Korean meeting scheduled at a liaison office in Kaesong, North Korea, had been canceled after the North Koreans said they would not be sending senior officials.
She refused to comment when asked if recent activity at North Korea's launch sites indicates a new missile test or "satellite launch" - i.e. a disguised missile test - might occur soon.
"I want to make it clear that the gangster-like stand of the USA will eventually put the situation in danger", AP quoted Choe as saying. He, however, offered no details on whether a new round of talks is being planned.
At the summit on February 27 and 28, North Korea asked for relief from five major United Nations sanctions and offered to dismantle a major nuclear weapons research site at Yongbyon, but the Trump administration insisted that North Korea surrender its entire nuclear program in exchange for economic benefits. Not quite. North Korea's tactic might be to hope this will initiate a reaction from the US.
Choe's remarks, in which she described the United States stand as "gangster-like", seem to point to a change in North Korea's strategy following the talks, with both Pyongyang and Washington initially voicing a readiness to continue on with negotiations.
"It's the administration's desire that we continue to have conversations around this", he said.
Choe also revealed that North Korean leader Kim Jong-un would soon decide whether to restart the North's nuclear and missile development programs.
At the State Department on Monday, Pompeo said that the North Korean offer in Hanoi "simply didn't rise to the level that was acceptable given what they were asking for in exchange".
Kim Yong Jae discussed cooperation in trade and the economy during the meeting with Russian Minister for the Development of the Far East Alexander Kozlov while Han attended a photo exhibition organized to mark the 70th anniversary of the late DPRK founder Kim Il Sung's official state visit to Moscow, said Yonhap.
She said it was entirely up to Kim whether to continue the launch and test moratorium, and said she expects he will "clarify his position" within a short period of time. Hanoi was supposed to be the part of the same old story where the USA accepted a meager offer from North Korea and declared diplomatic victory, only to watch the North Koreans take back everything they "gave away" a few months later and demand fresh concessions to refrain from further provocations.
Trump told reporters at the time that the USA would be unable to accept North Korea's request for total sanctions relief as a precondition for disarmament.
The tone of the North Korean Foreign Ministry, highlighting the lack of progress in the implementation of the denuclearization issue, is in stark contrast to the far more optimistic rhetoric from the U.S. special representative for North Korea, Stephen Biegun.
"This time we understood very clearly that the United States has a very different calculation to ours", she added.
Bolton, who has argued for a tough approach to North Korea, said last week that Trump was open to more talks but also warned of tougher sanctions if the North did not denuclearize.
Speaking of the issues regarding the DPRK, Chinese Premier Li Keqiang on Friday urged all parties to remain patient and to seize the opportunity to promote dialogue between the USA and the DPRK.
