South Korea Expands Espionage Law to Shield Semiconductor Technology

Legislative Change Targets Tech Leaks
The revision broadens the definition of espionage, which previously applied only to spying for North Korea, and elevates industrial theft to a national-security offense.
Background & Context
South Korea’s economy relies heavily on memory-chip exports from Samsung Electronics and SK Hynix. Government and industry reports warn that China’s rapid advances could soon overtake Seoul’s lead. Half of all detected cases involving leaks of sensitive technology to foreign entities in 2025 involved China, according to South Korean police data. Industry Minister Kim Jung-kwan warned in August that “China’s speed is beyond imagination,” underscoring the urgency. The United States has imposed export controls on China and the Pentagon blacklisted CXMT, a Chinese memory-chip firm, for security concerns.
Data & Statistics
- Ten former Samsung employees have been indicted for allegedly passing the 18-nm DRAM production process to CXMT, with prosecutors estimating a loss of 5 trillion won (?S$4.71 billion) in 2024.
- Over 85 % of tech leaks between 2020 and 2024 affected small or medium-sized businesses, according to data from lawmaker Choi Soo-jin’s office.
- CXMT’s global DRAM market share reached 10 % in Q2 2026 (Counterpoint Research), while Samsung and SK Hynix hold about 38 % and 25 %, respectively.
- Prior to the amendment, penalties for industrial espionage were limited to cases involving North Korea; the new law raises the maximum term to 30 years.
Official Statements & Responses
- Kim Jung-kwan emphasized the “intense urgency” of protecting chip technology from Chinese competition.
- Samsung declined to comment on the indictment.
- Chae Seong-joon, a military-science professor at Seokyung University and former intelligence official, warned that prosecution will remain difficult because the law still requires proof of nation-state involvement, calling the gap “huge” and exploitable by China.
Criticism & Opposition
- Chae Seong-joon argues that the requirement to demonstrate foreign-state participation creates a “huge blind spot,” limiting the law’s practical impact.
- Private investigator Jang Jae-woong reports a growing market for leak-prevention services, suggesting that existing corporate safeguards are insufficient to deter insider threats.
Verbatim Quotes
- “When Chinese companies need South Korean technology, they keep a list of specialists to contact with an offer of high salaries and benefits,” — Jon Woo-jung
- “The Americans are telling Korea: ‘Don’t be a weak link, stop leaking all your technology to China, stop exposing your supply chains, stop having Chinese investment in sensitive industries, because ultimately that also affects America’,” — Ben Forney, of Lazlo Intelligence, a corporate-intelligence firm
Conflicting Reports & Gaps
- The claim that 50 % of 2025 leaks involved China comes from South Korean police data; no independent source corroborates the figure.
- The amendment’s effectiveness is uncertain because the legislation does not clarify how prosecutors must establish the involvement of a foreign government, leaving a potential enforcement gap.
What’s Next
The revised espionage provisions become operative on September 13. Prosecutors are expected to apply the new penalties to ongoing cases, including the Samsung indictment, while industry players continue to bolster internal security measures.
