U.S. Investment Firms Sue South Korea Over Discriminatory Practices
Three prominent U.S. investment firms are initiating legal proceedings against the South Korean government, claiming it has implemented an unusual and discriminatory campaign against American-founded companies and investors.
In a bold move, investment firms GreenOaks, Altimeter, and Foxhaven have formally informed the U.S. Trade Representative (USTR) of their intention to pursue arbitration claims based on the U.S.-Korea Free Trade Agreement (KORUS). They’ve also requested that the USTR investigate South Korea under Section 301 of the Trade Act of 1974, a procedure typically used for vigorous U.S. trade enforcement actions.
The firms argue that South Korea’s treatment of Coupang—a U.S.-based tech company, often referred to as the “Amazon of Korea”—is not merely regulatory but a concentrated political assault. Coupang is significantly held by U.S. pension funds and individual investors.
As indicated in their filing, Coupang has faced targeted enforcement and increasing regulatory scrutiny for years, culminating in multiple investigations and audits that the company asserts exceed the levels of scrutiny faced by local competitors in South Korea and China.
The situation escalated after Coupang announced a data incident in 2025, involving a breach from a Chinese attacker that impacted about 3,000 accounts. While the stolen data did not include sensitive financial or personal details, South Korean officials responded by exaggerating the situation, referencing “tens of millions of victims” and alleging involvement of home invasion passcodes, claims that investors contest as unfounded and damaging.
Following this announcement, investors noted what they described as an overreaction by the government, leading to more than a dozen agencies getting involved against Coupang, including law enforcement and financial regulators.
The investment firms mentioned statements from senior South Korean officials that seemed to pivot from enforcement to overt political retribution. For instance, Prime Minister Kim Min-seok urged regulators to confront Coupang as rigorously as they would pursue organized crime, suggesting drastic measures like crippling fines and license cancellations.
Moreover, several Coupang executives, including Chairman Bom Kim and Chief Administrative Officer Harold Rogers, have reportedly been recommended for criminal prosecution by authorities.
This has had profound effects on American investors, leading to significant losses in market capitalization and affecting retirement benefits as well.
Interestingly, while the South Korean government intensifies scrutiny on U.S. companies, it is reportedly investing substantial resources to enhance its influence in Washington, a dual approach that critics argue is increasingly hard for U.S. lawmakers to overlook.
Lobbying records indicate that South Korea has spent over $300 million on lobbying efforts from 2016 to 2024, making it one of the biggest foreign spenders in the U.S., behind Japan and China. A quasi-governmental organization has dedicated around $100 million to promote favorable trade policies in Washington, while the embassy has engaged several lobbying firms.
Despite recent updates to trade agreements aimed at curbing undue regulations on U.S. companies, the narrative around Coupang seems to be used by South Korean lawmakers to justify expanding regulations, casting doubts on whether allies are genuinely supporting U.S. interests or merely leveraging American security commitments while creating uneven economic landscapes.
With legal actions underway, Washington faces the challenge of addressing potential discrimination against American investors and innovation. This situation may spark deeper conversations about the true nature of America’s alliances in the current geopolitical landscape.
