South Korea Espionage Law Takes Effect Expanding Spy Crimes Beyond North Korea to Protect Chip Technology

BLUFSeoul's new foreign-espionage statute gives prosecutors a dedicated tool to criminalize state-backed chip technology theft, and an initial indictment under the provision is likely within 12 months.

South Korea's expanded espionage law took effect on Sunday, broadening espionage offenses beyond acts benefiting North Korea to cover all foreign countries, according to Reuters 1. The National Assembly passed the revised Criminal Act on February 26, and the amendment creates a new offense for espionage on behalf of a foreign country or equivalent organization, carrying a minimum three-year prison sentence. Existing "enemy state" provisions remain unchanged 12. The National Intelligence Service said the change would strengthen its ability to prevent leaks of strategic technologies including semiconductors, displays, batteries and AI 2. The law follows last year's indictment of five former Samsung Electronics employees accused of transferring DRAM chip technology to China's CXMT 12. Asked whether the law targets Beijing, Chinese foreign ministry spokesperson Mao Ning said China expects other countries to provide a "fair, just, and non-discriminatory business environment" for its enterprises 2.

Analysis
South Korea's new foreign-espionage offense hands prosecutors a stand-alone charge for non-North Korea technology transfers, ending reliance on lighter trade-secret statutes whenever a foreign state or its proxy is involved. Read alongside Beijing's Counter-Espionage Law warning this cycle against US espionage, the legislation positions Seoul in an increasingly explicit allied counterintelligence alignment on semiconductor security. Prosecutors will likely secure a first indictment under the new foreign-espionage provision within 12 months; last year's Samsung-CXMT case already supplies an investigative template prosecutors can port onto the new charge. We have low confidence in this timing judgment, reflecting the absence of any announced pending case built on the new statute rather than the pre-existing enemy-state clause.
