South Korea expands espionage law to protect strategic technology

South Korea’s expanded espionage law took effect on Sunday, broadening the country’s legal definition of foreign spying as Seoul seeks stronger protection for semiconductor expertise and other strategic technologies.

The previous framework was focused primarily on espionage connected to North Korea. The revised law extends relevant offences to activity on behalf of all foreign countries, closing a gap that officials and industry groups said limited the prosecution of technology theft.

South Korea is home to major chipmakers and occupies a critical position in global semiconductor supply chains. Memory chips, advanced manufacturing processes and related equipment are increasingly treated not only as commercial assets but also as elements of national security.

The change reflects concern that conventional national-security laws were not designed for an era in which valuable information can include process knowledge, engineering data and industrial research rather than only military or diplomatic secrets.

Authorities will still need to prove the elements of an offence in individual cases. The expansion does not establish that every transfer of sensitive corporate information constitutes espionage, and companies will continue to rely on trade-secret, industrial-technology and criminal law alongside the revised statute.

Seoul has tightened controls around technologies designated as nationally important. The government has also sought to prevent unauthorized transfers of knowledge from semiconductor, display, battery and other advanced industries.

The policy challenge is to protect strategic assets without obstructing legitimate research, investment and international collaboration. South Korean companies operate globally and employ international workforces, while their supply chains depend on equipment and customers in multiple countries.

The law’s entry into force provides prosecutors with a broader national-security framework. Its practical impact will depend on implementing guidance, investigative standards and how courts interpret the relationship between foreign direction, protected information and demonstrable harm.

The measure arrives amid intensifying competition over chip manufacturing capacity and restrictions on the movement of advanced technology. Governments in the United States, Europe and Asia have introduced subsidies, export controls and screening mechanisms as semiconductors have become central to economic and military power.

The revised statute took effect on 13 September and removes the earlier limitation that tied core espionage offences mainly to North Korea. Reuters reported that the broader definition covers conduct connected with any foreign state, giving prosecutors a route to pursue cases involving technology or information sought by other governments.

South Korea has separately designated categories of national core technology and strengthened penalties for industrial leakage. The new espionage provisions do not replace those laws; they add a national-security basis where investigators can establish foreign direction and the other required elements of the offence.

No individual prosecution was announced as part of the law’s entry into force. Its effect will be tested when investigators and courts apply the expanded definition to specific conduct, evidence and alleged foreign beneficiaries.
