South Korean Regulators Threaten US Tech Ties Amid Growing Trade Friction

The piece argues that the US-South Korea economic bond stands at a crossroads, with joint AI investments—such as Samsung and SK Group’s $950 billion deals with Nvidia and Broadcom and AWS’s multi-billion-won cloud expansion—showcasing deep interdependence. Simultaneously, the Korea Fair Trade Commission has imposed fines that represent 95.5 % of the ten largest abuse-of-dominance penalties on American firms, including a prospective $550 million sanction on Google and proposed penalties on Analog Devices.

Multiple Korean agencies have also pursued extensive actions against e-commerce giant Coupang, resulting in a historic $409 million data-privacy fine and a $213 million tax assessment. US officials from President Donald Trump to Vice President JD Vance and FTC Chair Andrew Ferguson have warned that such targeting could trigger Section 301 investigations and tariffs. The article urges Seoul to resolve these regulatory disputes in ongoing trade talks or risk undermining a partnership that fuels growth on both sides of the Pacific.
