South Korea tightens espionage laws to shield semiconductor secrets

South Korea's revamped espionage law came into force on Sunday, marking a significant expansion of the nation's counterintelligence framework. Previously focused on threats originating from North Korea, the legislation now casts a wider net to criminalize espionage involving any foreign state or entity seeking to acquire sensitive technological information.

The legal overhaul comes as South Korea faces intensifying global competition in semiconductors, batteries and other cutting-edge industries deemed critical to national economic interests. Seoul has grown increasingly vigilant about protecting proprietary technologies and trade secrets from industrial espionage, a concern that extends across multiple trading partners and technology sectors.

The broadened statute grants authorities enhanced powers to investigate and prosecute cases involving the unauthorised transfer of sensitive information to foreign entities. Legal experts note the changes reflect a strategic pivot toward safeguarding intellectual property and manufacturing capabilities that underpin South Korea's technological leadership in key industries.

The expanded law represents part of a broader security strategy as Seoul navigates complex geopolitical tensions and rapid technological competition in Asia and beyond. Officials have signalled that protecting domestic innovation capacity remains a top priority as the country maintains its position in critical global supply chains.
