Due to the developments observed in North Korea's nuclear plants, South Korea revealed that it has been monitoring the movements in the facilities in order immediately detect any attempt for a missile launch.
"Stay away, or a different vote is counted as a betrayal", writes the North Korean refugees-organized web site "Daily NK" in South Korea.
Also Tuesday, South Korea's Foreign Ministry said it is anxious about the developments at North Korea's rocket launch site, and that Seoul and Washington have been closely monitoring the area. The images appear to show a rapid rebuilding at the country's main site for long-range satellite launches and missile-engine testing.
Chun In-bum, a North Korea expert and a retired three-star general, said it was "too early" to conclude the North was preparing for another rocket launch at Sohae.
"Please ensure that we never again hear the embarrassing talk that the president of the Republic of Korea is the top spokesman of Kim Jong Un", said Na, referring to South Korea by its formal names, as lawmakers from Moon's party began shouting at her.
The election for the 14th Supreme People's Assembly, however, has drawn attention from outside observers as its outcome could provide a rare glimpse of any shift in North Korea's very closed elite structure.
"It's certainly our expectation that we will be able to continue our close engagement", he said, while offering no specifics on when new talks might be held.
Biegun added that "it would hardly make sense to remove the threat of nuclear weapons from North Korea and endorse the continued presence of chemical and biological weapons". Noting that Kim has said he wants to complete denuclearization within Trump's term, Moon warned: 'If a Democrat is elected in the next election, policy toward North Korea could completely change'.
Undersecretary of State for Arms Control and International Security Andrea Thompson made the comment in a speech at the Carnegie Nuclear Conference in Washington.
The US side has included North Korea's chemical and biological weapons in the negotiations with Pyongyang.
There have also been reports from South Korea's intelligence service of new activity at a factory at Sanumdong near Pyongyang that produced the DPRK's first intercontinental ballistic missiles capable of reaching the United States.
And there have been claims that a rocket launch site is being rebuilt.
Both North Korea and the administration don't seem to see it that way, however, and say that there might be a fair bit of delay before the next summit. "I wonder if North Korea should avoid" such an action, Mr Moon said.
The North Koreans have repeatedly urged corresponding measures, but the USA has said no steps can be taken until Pyongyang first gives up its nukes.
