South Korea Scrutinizes Chinese Nuclear Firm’s Role In Local Power Plants

Seoul Officials Open Inquiries After U.S.-Blacklisted Company Is Found To Hold Stakes In Domestic Energy Projects

South Korean regulators and lawmakers opened inquiries this week after investigators found that China General Nuclear Power Group, a company placed on a United States trade-restriction list, has financial links to firms operating power generation sites in South Korea. The disclosures have prompted questions about oversight, investor screening and the potential for security risks tied to foreign ownership in critical infrastructure.

The arrangements involve multiple layers of subsidiaries and equity partners that mask direct ties, according to people briefed on the matter. Officials told reporters they are mapping corporate relationships to determine whether current disclosure rules were sufficient and whether any approvals were improperly granted. A regulator who spoke on background said transparency gaps made it difficult to assess who ultimately controls some assets.

Local residents and municipal leaders have expressed unease about the revelations, saying they want clearer reassurances on safety and governance. Energy analysts say the situation underscores how cross-border investment in modern grids and reactor-support services can complicate risk assessments, particularly when an investor is subject to foreign sanctions. One Seoul-based analyst said the finding forces policymakers to weigh short-term capital needs against long-term strategic exposure.

The U.S. placed the Chinese firm on its restricted list in 2019, accusing it of involvement in activities that could aid military programs; the company has denied wrongdoing in public statements. That designation has already limited the corporation’s access to some American technologies and suppliers, but it does not automatically bar investment in every allied country, creating a patchwork of rules that has caught regulators off guard.

Seoul’s energy ministry said it would review existing screening procedures for foreign investment in power-generation and related services and could propose tighter rules within months. Lawmakers signaled they may call hearings to examine whether national-security waivers were applied appropriately and whether statutory thresholds for foreign ownership need lowering.

Experts advising government agencies say the immediate priority should be better public reporting of who owns critical energy assets and why. But they also caution against knee-jerk moves that could scare away legitimate capital at a time when the country is trying to modernize its grid. For now, regulators face the task of untangling corporate ties while reassuring consumers that electricity supplies and safety standards remain intact.
