Kim Kwan-jin, top security adviser to ousted South Korean President Park Geun-hye, will visit the United States for two days from Wednesday, the presidential Blue House said Tuesday.
During his travel, Kim will meet with U.S. national security adviser Herbert McMaster to discuss countermeasures toward nuclear and missile threats from the Democratic People's Republic of Korea (DPRK).
The planned visit comes after Park vacated the Blue House on Sunday night and headed for her private home in a southern district of Seoul.
Park was permanently removed from office on March 10 as the constitutional court unanimously upheld the bill to impeach her.
Kim and McMaster held telephone talks on March 1 when the annual U.S.-South Korea springtime war game was launched.
During the talks, they agreed to deploy Terminal High Altitude Area Defense (THAAD) in southeast South Korea as scheduled to brace for what they said was nuclear and missile threats from the DPRK.
China and Russia have strongly opposed the THAAD installation, as it breaks regional strategic balance and damages security interests of the two countries.
Two mobile launchers and part of the THAAD battery arrived in South Korea last week and were transported to an unknown base of the U.S. Forces Korea. THAAD is composed of six mobile launchers, 48 interceptors, an X-band radar and a fire and control unit.
The THAAD battery, which Seoul and Washington agreed in July last year to install, is forecast to be deployed as early as next month.
