North Korean propaganda must be considered with wariness - Pyongyang has threatened for decades to reduce Seoul to a "sea of fire", for instance - but Monday's claim, if confirmed, would mark another big advance toward the North's goal of fielding a nuclear-tipped missile capable of reaching the USA mainland.
North Korea carried out another missile test Sunday and, unlike the test last month, this one was a success.
But along with keeping a strong defense against North Korea, President Moon also looks to engage with Pyongyang.
CD REV's Wang Zixin told The Associated Press that the group hopes to rally Chinese worldwide against the deployment of THAAD and demonstrate China's "tough stance" on the issue.
This was evident in the pro-engagement President Moon Jae-in's response to the North's latest missile test, where he ordered an urgent meeting of top security officials condemning the regime's move. It also vowed to fully implement the six sanctions resolutions previously adopted and urged all U.N. member nations to implement the measures "in an expeditious and serious manner". "I will work with the worldwide community to strongly handle the situation.".
However, during the closed-door meeting, China made no mention of a new sanctions resolution and renewed its appeal for talks to ease tensions on the Korean peninsula, according to diplomats. It flew to an altitude of 2,111.5 kilometers, and traveled 787 kilometers before landing in the Sea of Japan.
The video - viewed by yesterday more than 300,000 times on Facebook and Twitter and nearly 2.7 million times on the Chinese video-posting site Maiopai - represents the latest example of China's use of non-diplomatic channels to broadcast its displeasure with South Korea.
"Even new South Korean President Moon Jae-in, who favors a dialogue with the North and has called for dialing back the rhetoric on both sides, said on Wednesday that there is a 'high possibility" of conflict.
Instead, Washington and the caretaker government in Seoul sped up the roll-out of the missile system, announcing that it was partially operational a week before Moon was elected.
North Korea is not thought to be able yet to make a nuclear warhead small enough to mount on a long-range missile, though some outside analysts think it can arm shorter-range missiles with warheads.
"More importantly", he added, it "may represent a substantial advance to developing an intercontinental ballistic missile".
The North has vowed to develop a missile mounted with a nuclear warhead that can strike the mainland United States, saying the programme is necessary to counter US aggression.More news: Celebrating Bike to Work Day

The North defends its weapons programmes as necessary to counter U.S. hostility and regularly threatens to destroy the United States.
Face-to-face talks between Japan and South Korea leaders began in 2004 based on an agreement reached between the Japanese prime minister, Junichiro Koizumi, and South Korean President Roh Moo-hyun.
"(McMaster) said he is aware of the procedural problem in South Korea and understands it".
Clearly, Kim has no intention in giving up his country's nuclear weapons, as they have helped his hold on power and are his key bargaining chip in relations with other countries, especially the USA and South Korea.
Trump has called for an immediate halt to North Korea's missile and nuclear tests and US Disarmament Ambassador Robert Wood said on Tuesday that China's leverage was key and Beijing could do more.
In Seoul, some citizens expressed frustration.
Kim Do-hoon, 31, said that South Korea, while keeping the "door open for conversation" with the North, should also "show a stern attitude at some level".
China says its influence has been exaggerated and has called on South Korea and the U.S.to end large-scale wargames seen as threatening by North Korea in exchange for the North suspending its missile launches and nuclear tests.
So said President Donald J. Trump a little over a week ago about North Korean dictator Kim Jong Un.
Indeed, the administration's statement included an observation that seemed to contradict President Trump's initial comments about President Kim. "Having a missile test is not the way to sit down with the president, because he's absolutely not going to do it", she told ABC. The missile would have flown some 4,5oo kilometers if launched on a maximum trajectory.
In Washington, a U.S. defence official said the missile fired on Sunday appeared to be a liquid-fuelled KN-17, marking what seemed to be the most successful launch of such a device.
People living in Seoul would essentially have zero to six minutes - from the moment a missile is launched to the time it hits the target - to take cover in the event of a strike, Dr Schiller and Dr Wright said. North Korea is the rogue nation that has long envisioned uniting the two Koreas through the use of force.
