Filming Fighter Jets Gets Chinese Nationals Prison Time in Korea’s First Foreign Espionage Conviction of Its Kind

By ,

Two Chinese nationals who repeatedly photographed South Korean and US military facilities and attempted to intercept air traffic communications have been sentenced to prison in what is the first successful prosecution of foreign nationals under Korea’s general treason provisions. Here are the key points.

Issue

Can foreign nationals be convicted under the general treason provisions of the Korean Criminal Act for unauthorized photography of military aircraft and facilities — and does such conduct rise to the level of an act harmful to Korea’s military interests?

Facts

  • A (18) and B (20), both Chinese nationals who were high school students at the time the conduct began, entered Korea a total of three and two times respectively between the second half of 2024 and March 2025.
  • During those visits, they photographed military aircraft, air traffic control facilities, and related infrastructure hundreds of times at four Korean and US military installations — Suwon Air Base, Osan Air Base (K-55), Camp Humphreys (K-6), and Cheongju Air Base — as well as three major international airports: Incheon, Gimpo, and Jeju.
  • They also attempted to intercept communications between air traffic controllers and pilots using radio scanners near the airports and air bases, though those attempts did not succeed.
  • The two were caught on March 21, 2025, near Suwon Air Base after a member of the public noticed their behavior and reported it to police.

Court Decision

  • The Suwon District Court (Criminal Division 12, Judge Park Geon-chang) convicted both defendants on all charges.
  • A, as a juvenile, received an indeterminate sentence of between one year and six months and two years. B received a fixed sentence of two years.
  • The court found that the coordinated photography of military aircraft and the attempted interception of military communications constituted acts harmful to Korea’s military interests under the general treason provisions of the Criminal Act — making this the first case in which foreign nationals have been convicted under those provisions.
  • The court found that the photographs — showing aircraft deployment patterns and the operational activities of key installations — constituted a serious infringement of national security warranting firm punishment.
  • In mitigation, the court noted that B’s role in the interception attempts largely followed A’s lead, that A was a minor, and that neither defendant had a prior criminal record in Korea.

Key Takeaways

  • Systematic, repeated, and precision photography of military aircraft and installations by foreign nationals can constitute an act of general treason under the Korean Criminal Act, even without proof that the information was actually transmitted to a foreign government.
  • The general treason provisions of the Criminal Act apply to foreign nationals — this case establishes that for the first time through a conviction.
  • Attempted interception of military communications, even where unsuccessful, is independently chargeable and adds to the overall characterization of the conduct as a threat to national security.
  • The coordinated nature of the visits — multiple entries, multiple locations, systematic documentation — was central to the court’s finding that this went beyond casual photography into deliberate intelligence-gathering activity.

Why This Matters

This is a landmark ruling in Korean security law. Until now, the general treason provisions had not been successfully applied to foreign nationals, leaving a significant gap in Korea’s legal toolkit for responding to foreign intelligence activity that falls short of formal espionage charges. The conviction signals that Korean courts are prepared to treat systematic military photography by foreign nationals as a criminal act harmful to national security — not merely a civil or administrative matter. For security practitioners and policymakers, it also highlights the vulnerability of publicly accessible areas near military installations to low-tech but potentially high-value surveillance activity.
