"In each country, Secretary Tillerson will meet with senior officials to discuss bilateral and multilateral issues, including strategic coordination to address the advancing nuclear and missile threat from the DPRK, and reaffirm the Administration's commitment to further broaden and enhance US economic and security interests in the Asia-Pacific region," the department said in a statement.

The trip comes amid heightened tensions in the region in the wake of North Korea's successive missile launches and the killing of Kim Jong-nam, the estranged half brother of North Korean leader Kim Jong-un.

While in Seoul, Tillerson is scheduled to hold talks with South Korean Foreign Minister Yun Byung-se about how to deal with North Korean nuclear and missile threats as well as to further strengthen the alliance between the two countries.

The meeting with Yun comes after a 20-minute conversation held in Bonn, Germany, on the sidelines of a gathering of foreign ministers from Group of 20 nations last month. That was the first face-to-face talks between the top diplomats of the two allies under President Donald Trump's administration. 

Government sources in Seoul said that arrangements are being made to share the results of the second meeting either through a joint statement or press conference.

Tillerson is also expected to visit a US military base or the truce village of Panmunjom on the inter-Korean border during his trip to Seoul in an apparent gesture to reaffirm the steadfast alliance between South Korea and the US. (Yonhap)
