Clearly, sanctions and diplomacy ought to be the first steps toward resolving what's growing fears of a military confrontation.
In recent months, North Korea has launched a pair of intercontinental missiles believed capable of striking the continental USA and another pair that soared over Japanese territory.
China announced Saturday that it will limit exports of petroleum products to North Korea starting in October to implement the latest United Nations sanctions over Pyongyang's sixth nuclear test.
On Friday, Trump apparently responded in a tweet, saying Kim "will be tested like never before!"
North Korea has said it intends to build a missile capable of striking all parts of the United States with a nuclear bomb.
"We will not carry out export procedures of related products from 12 a.m. on the day of announcement and these products will be uniformly put on the list of prohibited export items in the future", it said.
Bruce Klingner, a former CIA Deputy Division chief for Korea told CNN that the new sanctions "do seem to be significant" and were the result of leverage brought to bear on the Chinese government by the White House.
During the council meeting, speaker after speaker including US allies in Europe and Japan spoke out in support of the 2015 nuclear deal that capped Iran's nuclear program, which President Donald Trump is threatening to scrap.
In the past, KCNA has occasionally not published English versions of crude insults directed at USA leaders or officials in an apparent effort to differentiate its statements for domestic audiences and outsiders. Sort of, hundreds of years ago, according to Merriam-Webster.
The quake was detected in Kilju county in North Hamgyong Province, where North Korea's known Punggyeri nuclear site is located, the official said.
"It could be a natural quake that really was man-made as the nuclear test would have transferred a lot of stress", he said. He characterized Mr. Trump's speech to the world body on Tuesday as "mentally deranged behavior". In a one-and-only such test in 1962, the US launched a nuclear-tipped ballistic missile from a submerged submarine.
The sanctions and restrictions have been getting tougher on North Korea in recent months.
The U.S. Geological Survey said that it detected a magnitude 3.5 quake in the area of previous North Korean nuclear tests, but that it was unable to confirm whether the event was natural.
"North Korea has repeatedly exceeded my expectations and Kim Jong Un in the statement has vowed to go beyond any expectation", said Kim, the analyst. His speech at the United Nations was "unprecedented" and "rude", and he should "exercise prudence in selecting words and to be considerate of whom he speaks to". North Korea has already been declared as a rogue state; so by definition it can do whatever it wants.
The world hasn't seen an above-ground, atmospheric nuclear test since an inland detonation by China in 1980, and North Korea upending that could push the region dangerously close to war.
