SEOUL, Sept 13 (Reuters) – South Korea’s expanded espionage law takes effect on Sunday, broadening espionage offences beyond acts involving North Korea to include all foreign countries as Seoul seeks to protect key technologies ​amid intensifying competition in semiconductors and other strategic industries.

Here are ‌more details:

• The National Assembly passed the revised Criminal Act on February 26 after years of criticism that existing laws were ill-suited to punish technology and industrial espionage involving non-North Korean actors.

• The amendment creates a new offence covering espionage for a foreign country ‌or ​equivalent organisation, carrying a minimum sentence of three ⁠years in prison. Existing provisions ⁠for espionage benefiting an “enemy state” remain in place.

• Under the previous law, espionage charges generally applied only to acts benefiting North Korea, forcing prosecutors in many cases involving foreign governments or companies to rely on ​other industrial technology or trade-secret laws.

• The National Intelligence Service welcomed the amendment when it was passed, saying it would strengthen South Korea’s ability ⁠to prevent leaks of strategic technologies such as ⁠semiconductors, displays, batteries and AI.

• Legal and security experts ​cited the change as closing a longstanding loophole that often left advanced industrial ​technology leak cases subject to lighter penalties, with supporters arguing it ‌will strengthen deterrence against industrial espionage.

• The amendment was promulgated on March 12 and takes effect after a six-month grace period on September 13.

• The change follows high-profile technology leak cases, including the indictment last year of five ⁠former Samsung Electronics employees accused of transferring key dynamic random-access memory (DRAM) chip technology to Chinese memory maker CXMT. Samsung and CXMT did not comment at the time.

• ⁠Asked whether the law, ‌which does not specify any country, could be seen ⁠as targeting Beijing, Chinese foreign ministry spokesperson Mao Ning ​said ‌China requires its enterprises to conduct international cooperation in ​accordance with ⁠international rules and laws. “At the same time, to this end, we believe that all countries should safeguard the normal investment and business activities of enterprises and provide a fair, just, and non-discriminatory business environment,” Mao told a regular news briefing on Friday.
