Kim Kwang-jin, a research fellow at South Korea's Institute for National Security Strategy (INSS), told RFA's Korean Service that Pence has sought to show that the USA doubts North Korea's intentions in using the Winter Olympics as a diplomatic channel to end its isolation.
Both Kim Yong-Nam, the North's ceremonial head of state, who is leading its delegation, and Mr Pence are due to attend the opening ceremony in Pyeongchang tomorrow, which could put them in the same room at a leaders' reception beforehand.

Tension soared past year as the North carried out multiple weapons tests, including intercontinental ballistic missiles capable of reaching the United States mainland, and by far its most powerful nuclear test to date.
Kim Yo Jong is Kim Jong Un's only sibling who is a member of North Korea's leadership.
