As global platform companies deliver services simultaneously across the world, individual countries' digital regulations are escalating into international trade disputes. Restrictions on cross-border data transfers, platform competition rules and data localization requirements are all seen by trading partners as a new form of non-tariff barrier. The United States, home to many large global platform companies, has raised a range of Korean digital regulations as major trade issues and demanded changes, including legislation on network usage fees, requirements for transferring location data and personal information overseas, the Cloud Security Assurance Program (CSAP) for public-sector cloud services, and rules on online platform monopolies.
At the core of the friction between the two countries is a structural difference in how each views the purpose and enforcement of regulation. Korea's restrictions on overseas data transfers under the Personal Information Protection Act are a legitimate exercise of sovereignty aimed at protecting individuals' right to control their own information. But for U.S. companies that rely on globally distributed data centers, they mean excessive compliance costs and service constraints. Online platform rules likewise aim to establish fair market order and protect consumers. Yet when quantitative thresholds such as revenue or user numbers are used, the result is de facto discrimination: even without formally distinguishing between domestic and foreign firms, U.S. big tech companies such as Google and Meta end up concentrated among the targets. More fundamentally, the U.S. prefers after-the-fact monopoly enforcement centered on antitrust suits and court rulings, while Korea has adopted a European-style model of prior regulation, making conflict difficult to avoid.
One face of this regulatory conflict emerged clearly in the Korean government's recent sanctions against a large domestic e-commerce platform owned by a U.S. parent company. After the company was referred to prosecutors in succession by the Fair Trade Commission and the Personal Information Protection Commission over allegations of manipulating product search rankings and a massive leak of personal data, and was hit with astronomical fines, U.S. investors and lawmakers cast the action not as ordinary law enforcement but as discriminatory regulation of a foreign-owned company. The U.S. side formalized due-process complaints as trade issues, citing simultaneous administrative investigations by multiple government agencies, the absence of attorney-client privilege and a lack of proportionality in calculating fines. The case showed how differences between Korea and the U.S. over the legitimacy and procedural fairness of enforcement can translate directly into trade disputes.
Resolving such trade friction and building a reasonable regulatory environment will require institutional reform on several fronts that reconciles regulatory sovereignty with international trade norms. As a matter of principle, Korea must first establish a non-discriminatory regulatory framework aligned with international standards. In designing rules, it should take a balanced approach that does not undermine market dynamism, rather than blindly copying foreign models of prior regulation. It should also be mindful that new digital rules can be difficult to enforce effectively against overseas operators, leaving domestic operators alone bearing the burden — a form of reverse discrimination.
Transparency and procedural legality in enforcement must also be strengthened substantially. The same standards for judging violations and the same principles for calculating fines should apply to domestic and foreign operators alike, and the process should be clearly disclosed to the public. The heavier a sanction — especially one that could threaten a company's survival — the more strictly the principle against excessive measures must be observed, with procedural controls comparable to a warrant requirement and full guarantees of the right to defense. It would also be desirable to make trade impact assessments mandatory as part of regulatory impact analysis when digital regulations are drafted. Whether a bill would amount to de facto discrimination against foreign-owned companies, whether it is consistent with international norms including the Korea-U.S. free trade agreement (FTA), and what effect it would have on cross-border data flows should all be reviewed systematically in advance.
In the end, the answer to the Korea-U.S. digital regulatory conflict is neither unconditional surrender of regulatory sovereignty nor special treatment for foreign companies. Korea should hold to its regulatory sovereignty in serving the public interest and protecting users, while being able to demonstrate the proportionality, fairness and transparency of both its regulatory procedures and their substance. The U.S., for its part, should not automatically treat legitimate public-interest regulation as a trade barrier — including cases where market or industry conditions justify special rules — and should respect Korea's legal system and social particularities. Ultimately, a sustainable solution will emerge only when the two countries build common digital norms grounded in mutual trust and shared interests.
