"Our government will consider every measure to prepare against North Korea's missile threats… If U.S. Forces Korea deploys THAAD, it will help our national security and defense," Kim Min-seok said, as quoted by the Yonhap news agency.
According to Kim, Washington has not offered Seoul any negotiations on the issue yet. However he added that the deployment was under discussion within the US government.
On January 6, North Korea announced it had successfully tested a hydrogen bomb, a move which triggered international condemnation for a provocative move destabilizing the region.
On January 13, South Korean President Park Geun-hye said that the deployment of THAAD systems in the country could be discussed, because of nuclear and missile threat from Pyongyang.
