Coupang Investor Urges US Trade Probe Over South Korea Treatment

A major investor in Coupang Inc. has urged the US government to investigate South Korea over what it alleges is discriminatory treatment of the American-listed e-commerce company, escalating a dispute that could spill into broader trade relations between Washington and Seoul.

Greenoaks Capital Partners LLC said it has filed a petition asking the Office of the US Trade Representative to investigate South Korea under Section 301 of the Trade Act, while separately notifying Seoul that it intends to file arbitration claims under the US-Korea free trade agreement.
