And after a March high-thrust rocket engine test, North Korean leader Kim Jong Un said "the whole world will soon witness what eventful significance the great victory won today carries". Some experts, including officials in Tokyo, estimated Sunday's launch successfully tested a new type of missile, potentially the longest-range in North Korea's arsenal. The missile flew roughly 430 miles, but the weapon was intentionally lofted.
More significant, however, was that it flew higher and for longer than previous missiles.
Russian Federation has shown concern about Pyongyang's missiles, but it may also see North Korea as an opportunity to gain leverage with the West, the U.S. in particular, according to CNN Moscow Bureau Chief Matthew Chance.
"The United States maintains our ironclad commitment to stand with our allies in the face of the serious threat posed by North Korea", the statement said.
The North's KCNA news agency said Sunday's test launch verified the homing feature of the warhead that allowed it to survive "under the worst re-entry situation" and accurately detonate.
ABC News takes a look at what we know and don't know about the latest North Korean missile launch.
Outsiders express more skepticism about North Korea's nuclear warhead claims.
"What would change the strategic balance is an ICBM capable of reaching the United States mainland", he said. It was purposely shot at a high angle to avoid directly hitting a surrounding country, but it still traveled 489 miles and got as high as 1,312 miles, according to North Korea's state-run news agency - and landed near Russian Federation.
Many also agree that the North has yet to master the "atmospheric re-entry" technology for an ICBM.
The U.S. military's Pacific Command said the type of missile that was sacked was "not consistent with an intercontinental ballistic missile".
Why fire the missile at such a high altitude? "That's the good news", Union of Concerned Scientists co-director David Wright told VOA.
Kim said North Korea would stage more nuclear and missile tests in order to ideal nuclear bombs needed to deal with U.S.
KCNA cited Kim as saying that the United States strategy of what it called "militarily browbeating only weak countries and nations, which have no nukes" would never work on the North.
KCNA said Kim accused the United States of "browbeating" countries that "have no nukes", warning Washington not to misjudge the reality that its mainland is in the North's "sighting range for strike". It again demanded that Pyongyang conduct no further nuclear or ballistic missile tests.
Mr Putin said nuclear tests of the type that Pyongyang had been carrying out in recent weeks were unacceptable, but that a peaceful solution to rising tensions on the Korean peninsula was needed.
U.N. Secretary-General Antonio Guterres is condemning the latest North Korean ballistic missile test as a violation of Security Council resolutions and a threat to peace and security in the region. But it called for restraint to avoid increasing hostilities in the area. The Secretary-General calls on the DPRK to ensure full compliance with its global obligations and return to the path of denuclearization.
The US ambassador to the UN, Nikki Haley, said on Sunday that until Mr Kim met the US conditions, "we're not sitting down with him".
Kim Jong-un said that DPRK was a worthy nuclear power whether someone recognizes it or not, as reported by Yonhap News. But Haley said "having a missile test is not the way to sit down with the president, because he's absolutely not going to do it". After all, North Korea continues to test better and better missiles despite the harsh sanctions that have already been imposed, especially since its first nuclear test in 2006. Yet 38 North also says new assessments of what North Korea's missile program can do are now necessary. We want to hear from you. Hai Do was the editor. Write to us in the Comments Section.
