Two Former Chinese Military Personnel Arrested in South Korea for Intercepting US-ROK Fighter Jet Communications and Collecting Intelligence on US Forces

BLUFUndetected PRC recruitment inside Camp Humphreys for three and a half years, paired with tactical SIGINT nearby, exposes counterintelligence seams around US forward-deployed forces that indictments, very likely within 30 days, will not close.

South Korea's Gyeonggi Nambu Provincial Police arrested two former Chinese military service members on Monday on charges of benefiting the enemy, police said Tuesday 12. One suspect, a man in his 60s who retired from the People's Liberation Army, allegedly used a software-defined radio receiver, antenna, and laptop set up at a hotel near Gunsan Airport to intercept fighter jet communications between South Korean and US pilots and air traffic control on multiple occasions since January 2024 234. The second suspect, a 45-year-old ethnic Korean with Chinese nationality who ran a military supply store near Camp Humphreys, is accused of recruiting a South Korean employee at the base from November 2021 to May to obtain classified material on US-Korea exercises, weapons movements, and personnel changes among US military leadership, allegedly paying her for the information 234. Police said they are examining the first suspect's laptop to determine whether intercepted communications were relayed to Chinese authorities and are investigating whether the Korean employee acted as an accomplice 23.

Analysis
Charging both suspects with benefiting the enemy rather than espionage leaves China formally unaccused despite evidence of sustained signals collection against US-ROK air operations and paid recruitment inside Camp Humphreys, and prosecutors very likely will indict at least one on national security charges within 30 days, ahead of the September 13 espionage-law amendment that would otherwise strengthen the case. Moderate confidence reflects converging Korean police-sourced reporting, corroborated independently by Washington Times wire coverage, on charges and timeline, but no independent confirmation that intercepted communications reached Chinese authorities. The claimed hobbyist and business rationale could still reflect genuine amateur activity absent proof of transmission to Chinese state authorities. The Humphreys recruitment ran undetected for three and a half years; paired with the parallel Chen Dingwei military-export case, this points to PRC collection working both human-source and hardware channels, and an indictment on national-security grounds would push USFK to tighten local-national vetting before upcoming allied exercises.
