Competition & Antitrust Law in South Korea

Competition and antitrust law in South Korea is the professional legal and regulatory function through which commercial agreements, market conduct and business combinations are assessed under the Monopoly Regulation and Fair Trade Act, commonly known as MRFTA. Korea Fair Trade Commission is the central authority.

Korean competition analysis begins with commercial facts: the parties, relevant markets, agreement terms, pricing, market shares, customer alternatives, worldwide assets or turnover, Korean domestic sales, transaction structure and internal decision records. Matters may concern unfair collaborative acts, abuse of market dominance, unfair trade practices, mergers, share acquisitions, business transfers, joint ventures or interlocking directorates.

South Korea has an independent competition regime outside the EU and EEA. Korean analysis may nevertheless require coordinated work with United States, EU, Chinese, Japanese, United Kingdom and other competition authorities in cross-border transactions or conduct affecting multiple markets.

A distinctive Korean feature is its combination of transaction-specific reporting rules with pre-closing notification for certain large-scale corporations and post-closing notification for other reportable business combinations. Foreign-to-foreign transactions require a separate Korean domestic-sales nexus assessment.

This section defines the practical boundaries of the Competition & Antitrust Law Registry Object. It distinguishes Korean competition law from broader commercial, consumer, unfair-competition, foreign-investment, securities, data and corporate work that may connect to a matter without forming its primary competition-law issue.

The purpose of Korean competition and antitrust law is to promote fair and free competition by preventing abuse of market dominance, harmful collaborative conduct, unfair trade practices and anti-competitive business combinations.

1. Identify whether the issue concerns an agreement, conduct, market dominance, share acquisition, merger, asset acquisition, joint venture or interlocking directorate.
2. Confirm worldwide assets or turnover, Korean domestic sales, voting-right effects, transaction type and relevant markets.
3. Assess whether general thresholds and, for foreign parties, local Korean domestic-sales conditions are satisfied.
4. Determine whether the report is pre-closing or post-closing based on the parties' size and transaction form.
5. Assess substantive competition effects even when compulsory reporting is not required.
6. Implement the appropriate legal and operational path before conduct begins or a transaction closes.
