Chang Ho-jin, the newly appointed foreign policy adviser to President Yoon Suk Yeol, arrived in Washington, D.C., on Thursday to engage in discussions with officials regarding the alliance between South Korea and the United States, the upcoming US election, and other bilateral issues. This visit follows Chang's recent unexpected reassignment from his role as South Korea's top national security adviser to the newly created position of special adviser for foreign and security affairs in President Yoon's administration. Upon his arrival at Dulles International Airport, Chang expressed his intention to address the effective conclusion of issues such as the South Korea-US alliance during the remaining term of the Biden administration. He also mentioned his plan to discuss his new responsibilities and gain insights into the unfolding US presidential election. Additionally, he highlighted that the new unification strategy outlined by President Yoon in his Liberation Day speech would be a key topic for discussion during his meetings in Washington. Chang's replacement and the subsequent appointment of a new defense minister have sparked speculation about the reasons behind the reshuffle, including the relationship between President Yoon and the new defense minister, Kim Yong-hyun. The outgoing defense minister, Shin Won-sik, has succeeded Chang as President Yoon's top security aide and will continue to serve as defense minister until his successor undergoes a parliamentary confirmation hearing. Chang, a seasoned diplomat and former vice foreign minister, had assumed the role of national security adviser in January.
