South Korea moved to contain diplomatic fallout from its investigation into e-commerce giant Coupang on Wednesday, with National Security Adviser Wi Sung-lac assuring the United States that the row is not impeding broader discussions on trade, investment or security matters between the two allies.
The dispute has emerged as an unexpected friction point in the Seoul-Washington relationship. U.S. officials and business organisations have publicly expressed concern that South Korea is unfairly targeting the Seattle-based company, which operates one of Asia's largest online shopping platforms. The case centres on a massive data breach that exposed customer information, though the two sides remain at odds over the scale of the incident.
Wi rejected Coupang's characterisation of the breach, asserting that South Korean authorities have established that more than 33 million records were compromised. The company has disputed this figure, claiming the incident affected approximately 3,000 records. "That fact has been established," Wi told journalists at a briefing in Seoul. "Discussions should start from that point." His remarks underscored Seoul's determination to defend the rigour of its regulatory investigation while simultaneously signalling that the matter would not derail broader alliance priorities.
The National Security Adviser framed a recent high-level meeting between South Korea's ambassador to the United States and senior government officials as a comprehensive review of bilateral relations rather than a forum focused solely on resolving the Coupang controversy. He acknowledged that the company's situation did feature in conversations, but emphasised that Seoul and Washington had agreed to address multiple pending issues in a coordinated and holistic manner. This messaging appears calibrated to reassure Washington that Seoul views the Coupang matter as a discrete regulatory issue rather than a symbol of broader protectionism or anti-American sentiment.
On the critical question of whether security and strategic consultations have been affected, Wi provided explicit reassurance. "There are no signs that security consultations are being delayed because of them," he stated, referring to the various outstanding disputes between the countries. This statement carries particular weight given the sensitivity surrounding U.S.-South Korea defence cooperation in an era of regional tensions with North Korea and China's rise.
The investment dimension looms large in current bilateral negotiations. South Korea made a landmark commitment of $350 billion in direct investment in the United States, a pledge that has become central to managing the relationship and offsetting American concerns about trade deficits. Wi confirmed that discussions regarding this substantial commitment continue, though he cautioned that no immediate concrete outcomes have materialised. He described investment as the single most significant issue in the bilateral relationship, signalling Seoul's willingness to prioritise this area as a means of strengthening ties and demonstrating commitment to the U.S. economy.
Tariff concerns represent another dimension of ongoing trade discussions. Wi indicated that South Korea anticipates Washington may invoke Section 301 of the U.S. Trade Act—a controversial provision that allows the president to impose sanctions on trading partners deemed to have engaged in unfair practices—potentially connecting such action to forced labour concerns. However, he suggested that Seoul's understanding is that any such measures would remain within the broader tariff framework already being negotiated. Last year, the U.S. reduced its tariff rate on South Korean imports to 15 percent, down from a threatened 25 percent, following Seoul's investment pledge and commitment to purchase $100 billion worth of American energy products. This precedent provides a template for how the two nations have managed trade tensions in recent months.
To underscore commitment to resolving lingering trade issues, South Korean Industry Minister Kim Jung-kwan departed for Washington on Wednesday to engage senior U.S. officials on trade and investment cooperation. His visit signals Seoul's proactive approach to maintaining dialogue and demonstrating responsiveness to American concerns across multiple economic fronts.
Beyond conventional trade and investment matters, Seoul is monitoring developments in nuclear energy cooperation that could carry indirect implications for South Korea's own strategic interests. Wi noted that a U.S.-Saudi nuclear energy agreement warrants close observation, reflecting broader regional concerns about how major powers structure their technological and energy partnerships in ways that might affect South Korea's own diplomatic positioning and economic interests in the Middle East and beyond.
On the sensitive issue of uranium enrichment and spent-fuel reprocessing, Wi stressed that no obstacles exist to ongoing security consultations with Washington on these nuclear-related matters. The two countries held talks on this subject in June and are preparing a second round of discussions. Such consultations are critical given South Korea's significant nuclear energy sector and the need to align proliferation concerns with energy security requirements. Wi indicated flexibility regarding format, noting that Seoul stands ready to send delegations to the United States for further discussions if circumstances warrant, underlining the priority Seoul attaches to maintaining substantive security dialogue despite various bilateral disagreements.
