The sanctions were to force North Korea to drop the development of weapons programme but the country went ahead to test fire Intercontinental Ballistic Missiles (ICBM) and later detonated small hydrogen bomb that shook Chinese and Russian territories to the amazement of the world, particularly, United States of America.
The North Korean leader later expressed satisfaction with the visit and said it's important to continue dialogue.
They had been watching the hockey match between Japan and the unified team representing North and South Korea when he stood up to bust a few moves. "There were a couple of major outlets that were writing fluff pieces about Kim Jong Un's sister who'd come here, saying she's the new Ivanka Trump and all these odd comparisons they were making to someone who is the head of propaganda, was under United Nations sanction for helping to run North Korea's political prison program".
This shouldn't come as any surprise.

Seoul had banned all North Korean ships entering its ports after the North Korean torpedo attack in 2010 - the event that Pence will commemorate during his visit.
The athletes earned a personal best in their short program and were well-received by the crowd in Pyeongchang, South Korea. They technically required special invites to compete in PyeongChang as well, as they failed to confirm their participation by the deadline and lost their spot to Japan.

"We didn't reach the same level as we did as in practices", Ryom said last month, according to the International Skating Union.
"I think that he would be willing to adopt a sunshine policy, in other words indefinite, unconditional aid to the North Koreans", he said. That changed immediately when Ryom, 19, and Kim, 25, took the ice for warm-ups. At the very least, they will likely turn some heads.
He said North Korea "needs to get out of this unsafe situation, but needs to save face as well".
During her three-day visit, Ms Kim fascinated South Koreans with her relaxed manner and gentle smile, and was touted by global media for scoring a diplomatic gold.
"We've said for some time it's really up to the North Koreans to decide when they're ready to engage with us in a honest way, a meaningful way", Tillerson told reporters in Egypt.
The North Koreans won't shed any light on those mysteries when they perform at the Games.
NYT made the claim that Kim Jong Un's sister out-charmed Vice President Mike Pence. If they continue their current course, they will certainly achieve that goal. "They know what has to be on the table for conversations".
With the North Korean official's attendance at the Olympics raising hopes of high-level inter-Korean talks, Pence stopped short of ruling out the prospect that he could meet senior North Korean officials, despite President Donald Trump having cast doubt on US negotiations with Pyongyang anytime soon.
