The data breach at Coupang is escalating into a trade conflict between the United States and South Korea. In South Korea, discussions are underway regarding corporate responsibility following the massive leak of customer information. However, the U.S. House Judiciary Committee claims that the South Korean government's investigation and sanctions represent discriminatory actions targeting American companies.
 
On July 1, the House Judiciary Committee released an interim report addressing regulatory issues concerning U.S. companies in South Korea. The report stated that South Korean authorities have excessively pressured American firms, including Coupang Inc., the parent company of Coupang, through investigations and potential criminal liabilities, thereby restricting competition.
 
The report does not deny Coupang's responsibility for the data breach. Instead, it criticizes the South Korean response as disproportionate to the incident's scale. According to the report, Coupang reported to authorities that a former employee had unauthorized access to customer information. The company later clarified that the actual extent of the breach was smaller than initially feared during its internal investigation.
 
The House noted that South Korean authorities continued extensive investigations into Coupang after the incident. The report indicated that there were dozens of investigations and thousands of document requests. It also mentioned large-scale inquiries involving employees and suggested that management faced undue pressure regarding potential criminal liability.
 
One of the most controversial points in the report involves the National Intelligence Service (NIS). It claims that the NIS demanded Coupang retrieve equipment and statements related to former employees in Shanghai, China. The report also alleged that divers were deployed to recover a laptop discarded in a river. Although the NIS denied any involvement, the House report argued that Coupang's documents and testimonies contradict the NIS's claims.
 
Domestically, the data breach has direct implications for consumer harm. Issues of corporate accountability and user protection remain unresolved. The central debate now revolves around whether the enforcement of data privacy laws is justified or if it constitutes excessive measures targeting specific foreign companies.
 
The House has expanded the issue to encompass regulations affecting online platforms and technology companies. The report asserts that South Korean regulatory bodies, including the Fair Trade Commission, have repeatedly conducted rigorous investigations and sanctions against American firms. It also highlighted that U.S. tech companies like Google and Netflix have faced various inquiries in South Korea.
 
The House believes that South Korea's regulatory approach complicates market competition for foreign companies. The report claims that South Korean authorities have used competition laws and digital regulations to protect domestic firms while applying stricter standards to American companies. It interprets the Coupang incident not merely as an isolated data breach but as indicative of the regulatory environment in South Korea.
 
The actions of South Korean authorities are said to have impacted Coupang's investors and partner companies. Given that many American firms sell products through Coupang, the enforcement of South Korean regulations could lead to harm for both U.S. companies and consumers. This connection is what has prompted the House to link the issue to trade matters.
 
The likelihood of this issue escalating into a trade dispute has increased. The House Judiciary Committee argues that South Korea's actions violate U.S.-South Korea trade agreements. As Congress scrutinizes the Coupang incident, it may leverage concerns about South Korea's regulatory framework in future trade negotiations or discussions regarding online platforms.
 
Meanwhile, Coupang expressed regret over the situation that led to the House Judiciary Committee's investigation, stating, "We are committed to finding constructive solutions that strengthen the U.S.-South Korea alliance and promote trade and investment beneficial to both countries."
