Stephen Biegun is reportedly coming to South Korea on Tuesday ahead of a scheduled trip to Japan.
All eyes are on the U.S. Deputy Secretary of State's possible visit since he hasn't step foot on South Korean soil in seven months.
It also comes at a time where tensions are escalating on the peninsula as well as between the U.S. and North Korea.
Details of his visit have not been confirmed yet, but he's expected to stay in Seoul for three daysvisiting the Blue House and meeting with his South Korean counterpart Lee Do-hoon on North Korea issues.
In June, Biegun urged Pyeongyang to return to the negotiation table, saying that reaching a deal depends on the North, adding the U.S. has detailed plans to make progress quickly if North Korea re-engages.
However, his comments were directly rebutted by North Korea.
The North's First Vice Foreign Minister Choe Son-hui said the discussion of a possible summit between the U.S. and North Korea ignores the reality on the ground.
However watchers still say this could be the North's attempt to pressure the U.S. for revised negotiations.
The possibility of the two countries holding a summit was also implied by South Korea's Blue House.
But considering the sensitive issue comes in the run up to the U.S. presidential election in November, experts say Biegun's visit is not expected to move the needle that much.
