Seoul: The South Korean government is anticipated to face criticism over its diplomatic oversight following the U.S. Department of Energy's decision under the Biden administration to categorize South Korea as a "sensitive country." This development has sparked concerns about Seoul's ability to maintain effective communication with Washington and uphold diplomatic relations, particularly as it occurs amidst a leadership vacuum caused by the impeachment of President Yoon Suk Yeol, following a failed martial law attempt.
According to Yonhap News Agency, the Department of Energy (DOE) placed South Korea in the lowest category of its "sensitive and other designated countries list" (SCL) in early January during the Biden administration. Since that decision, there have been no new restrictions on bilateral science and technology cooperation with South Korea, as confirmed by a DOE spokesperson. If this designation is implemented on April 15, it could impede South Korea's participation in U.S. research on advanced technologies, including atomic energy, artificial intelligence, and quantum technology.
The South Korean foreign ministry seems to have been unaware of the DOE's decision until recently. Its initial reaction to a related news report was to state that the government is "verifying the matter with related ministries." Foreign ministry spokesperson Lee Jae-woong later noted that the DOE's sensitive country list has not been finalized and that South Korea is in "close consultation" with the U.S. regarding the issue.
Foreign Minister Cho Tae-yul informed a parliamentary session that South Korea was "informally" notified that the DOE was considering categorizing it as a "sensitive country" and that the issue has been raised with the DOE. Despite the political turmoil caused by Yoon's martial law attempt and impeachment, the South Korean government maintains that the alliance with Washington remains "ironclad."
It is unclear why the Biden administration decided to place South Korea on the SCL, especially amid rising calls in South Korea to consider its own nuclear armament in response to North Korea's nuclear threats. Initially, it was speculated that the decision was reviewed under the Trump administration, but experts suggest that political instability caused by Yoon's actions may have influenced the DOE's designation.
The SCL is a list of countries subject to particular consideration for policy reasons during the DOE's internal review and approval process for foreign national access, as per the DOE website. Countries may appear on the list for national security, nuclear nonproliferation, or terrorism support reasons, including North Korea, China, and Russia.
In January, Jake Sullivan, then U.S. National Security Adviser, described Yoon's failed martial law as "shocking" and "wrong," while affirming the structural health of the South Korea-U.S. alliance. If the DOE's designation proceeds, it could test the Seoul-Washington alliance under the transactional approach of U.S. President Donald Trump, experts noted.
