"We will continue to intensify our maximum pressure campaign until North Korea takes concrete steps for complete, verifiable and irreversible denuclearization", Pence said, calling on South Korea to work in tandem.

The response was seen as meaning that there should first be progress on efforts to resolve the North Korean nuclear standoff, such as talks between the United Sates and the North, before what would be a third inter-Korean summit takes place.
Possible concessions would include a USA agreement to further delay military drills, and for North Korea to hold off further weapons tests and agree to pursue denuclearization talks.
However, some experts argue that while Kim Yo-jong's visit may lay out the foundation for smoother inter-Korean ties after the PyeongChangOlympics, it is too early to link it to a summit.
On his way to Asia earlier this week, the USA vice president told reporters he was not seeking direct talks with North Korean officials, "but we'll see what happens".

Kim Eui-kyeom, South Korean president's spokesman, said at a news conference in Seoul on Saturday that the North Korean delegation delievered the invitation letter at a landmark high-level meeting at the presidential palace in Seoul.
South Korea has been using the Pyeongchang Games to break the ice with the reclusive North, which has been trading nuclear threats with the United States recently. "We get along personally, so I believe that Donald Trump and Kim Jong Un, if they talked, they'd probably get along".
"To see it finally happen, it really did not only give me goosebumps, but I think the whole public and I guess the entire world", said Bach.
