He said that since Yun's visit to the US for such talks could be impossible due to scheduling restraints, the ministry is also consideration arranging meetings on the sidelines of international events scheduled for February. 

His remarks are in line with the ministry's earlier policy report in which it is trying to have meetings between Yun and Rex Tillerson, Trump's nominee for secretary of state, arranged as quickly as possible.

The move is viewed as a way to build up closer communication with the new government and strengthen the alliance at a time when Seoul is facing a leadership vacuum in the wake of the parliament's impeachment of President Park Geun-hye last month over alleged corruption scandal. 

Since Trump's surprise win in the presidential election late last year, concerns have been mounting that the alliance between Washington and Seoul could weaken and eventually hamper cooperation in many major issues including North Korea's nuclear threat. 

Trump has demanded fair cost-sharing for the US troop presence in South Korea, while arguing that a free trade deal with Seoul is killing jobs for US citizens and that there could be renegotiations on the agreement reached years ago. On the campaign trail, he even mentioned a possible withdrawal of US troops from South Korea. (Yonhap)
