Korea tightens cross-border M&A reviews on core industrial technologies

South Korea has expanded its regulatory oversight of cross-border mergers, foreign acquisitions, and outbound joint ventures involving strategic technologies, granting government authorities direct injunction powers to halt or unwind unauthorized transactions before investigative proceedings conclude. The sharpened regulatory regime, anchored by amendments to the Act on Prevention of Divulgence and Protection of Industrial Technology that took effect in July 2025 alongside successive revisions to the national core technology roster by the Ministry of Trade, Industry and Energy, establishes a rigorous pre-closing review framework for domestic enterprises holding state-designated capabilities across semiconductors, secondary batteries, display panels, advanced materials, and precision manufacturing.

Under the amended statutory architecture, the scope of government scrutiny over foreign investment moves beyond traditional national defense considerations to formally examine broader ramifications on the national economy. To execute these evaluations, the trade ministry established a dedicated M&A Expert Committee composed of financial, corporate valuation, and cross-border legal specialists. This specialized panel evaluates transaction structures, technological dependencies, overseas manufacturing transfers, and ultimate beneficial ownership before the overarching Industrial Technology Protection Committee delivers a final determination on export approvals or foreign acquisition filings.

The regulatory framework targets the legal mechanisms through which proprietary industrial expertise transfers abroad. While outbound transfers of government-funded national core technologies require prior approval from the trade minister, privately funded assets require formal advance notification. Under the amended law, transactions that previously relied on ambiguous corporate structuring such as offshore holding company transfers, indirect share acquisitions, or joint venture arrangements where foreign entities assume operational control face mandatory pre-deal disclosures. The statute establishes an official registration system for institutions holding national core technologies and authorizes the trade ministry to issue ex-officio notifications compelling companies to confirm whether their assets constitute designated national core technologies, carrying administrative fines of up to 10 million won ($7,300) for non-compliance.

The most significant operational shift for cross-border dealmakers is the introduction of immediate ministerial injunction powers. If the Ministry of Trade, Industry and Energy detects an unapproved or unreported foreign acquisition, joint venture, or unauthorized technology transfer, the trade minister can issue direct administrative orders demanding the immediate suspension, prohibition, or full restoration of the transaction to its pre-deal status. These orders can be executed prior to the conclusion of formal investigative agency inquiries or full committee deliberations. To enforce compliance, regulators introduced a recurring daily penalty of up to 10 million won ($7,300) per day for each day an entity fails to execute a ministerial suspension or unwinding order.

Penalties for illicit technology transfers have also increased substantially. The statutory cap on punitive civil damages for willful technology infringement rose from three times to five times the verified damages. Criminal fines for individuals and corporate entities that transfer designated national core technologies abroad with knowledge that the asset will be used overseas were raised from a previous ceiling of 1.5 billion won to up to 6.5 billion won ($4.7 million), alongside existing criminal imprisonment terms.

These enforcement tools coincide with targeted expansions of the underlying technological scope. In July 2024, the trade ministry revised the Public Notice on Designation of National Core Technologies, adjusting the catalog to 76 technologies across 13 industrial sectors by adding gas turbine hydrogen combustion capabilities and high-speed rail vehicle chassis engineering while refining the boundary definitions of 24 existing items in semiconductors, shipbuilding, and robotics. A subsequent revision effective in October 2025 under MOTIE Notice No. 2025-2 incorporated three additional high-precision industrial capabilities: multilayer ceramic capacitors with an ultra-high capacitance density of 21 microfarads per cubic millimeter or higher, zinc smelting utilizing hematite metallurgical processes, and spaceborne synthetic aperture radar payload fabrication, while reclassifying technical specifications for 15 technologies across six sectors.

For multinational corporations, private equity funds, and cross-border legal counsel structuring inbound investments or outbound industrial partnerships in South Korea, the revised legal framework elevates national core technology due diligence from a routine regulatory inquiry into a primary transaction gate. Deal timetables for corporate carve-outs, cross-border equity sales, and technology-licensing joint ventures in high-technology manufacturing now require comprehensive early-stage asset classifications and formal coordination with the trade ministry prior to closing.

The Ministry of Trade, Industry and Energy and the Korea Planning and Evaluation Institute of Industrial Technology conduct ongoing annual surveys across domestic industrial associations and research bodies to identify emerging commercial technologies for future national core technology designations.
