South Korean police have arrested two ex-Chinese military servicemen for alleged espionage activities targeting US forces and military operations in the region.
Washington DC, United States Aug 13, 2026 ALN: Two former Chinese military servicemen have been arrested in South Korea in separate cases of apparent espionage, involving alleged attempts to surveil South Korean military operations and US forces stationed in the country, police said. These incidents highlight ongoing concerns regarding espionage activities in the region, particularly given the strategic military alliances and tensions that characterize East Asia.
In one case, a man is accused of intercepting flight communications near an airbase where US fighter jets are based, while in the other, information about military drills between US and South Korean forces was allegedly obtained. The implications of such espionage activities are significant, as they threaten not only the security of South Korea but also the broader stability of US military operations in the region.
South Korea is a key ally of the United States in Asia, and hosts its largest overseas military installation. The presence of US forces in South Korea has been a point of contention in regional politics, particularly with North Korea and China. The military alliance between the US and South Korea is designed to deter aggression from North Korea, which has been known to conduct provocative military actions and maintain a hostile stance toward both its southern neighbor and the United States.
Both men have been charged with aiding an enemy state. In response to CNN’s request for comment, China’s Foreign Ministry said it was “not familiar with the situation.” This statement reflects a common practice among state actors to downplay or deny allegations of espionage, particularly when the accused are former military personnel. The response from the Chinese government also indicates the sensitivity surrounding issues of national security and intelligence, especially in the context of US-China relations, which have been strained in recent years.
In 2022, a Korean-Chinese man in his 40s allegedly developed a personal relationship with a Korean woman who worked at Camp Humphreys – located in Pyeongtaek about 40 miles south of Seoul. The base is home to US Forces Korea and other major commands, making it a key center for US military operations and readiness on the Korean Peninsula. This incident underscores the tactics often employed in espionage, where personal relationships can be leveraged to gain access to sensitive information.
Korean media reports say the man gave the woman money for military information about the base. The Gyeonggi Nambu police national security investigation division said the man obtained information about US-South Korea joint military exercises, including Ulchi Freedom Shield, as well as changes in command positions, police said. The Ulchi Freedom Shield exercise is an annual joint military exercise conducted by the United States and South Korea, aimed at strengthening their combined defense capabilities and readiness. The exercises typically involve large-scale drills that simulate responses to potential North Korean aggression.
Authorities have informed the US military about the case. This year’s Ulchi Freedom Shield drills are due to start next week, emphasizing the urgency and seriousness of the investigation. The timing of these arrests, just prior to the commencement of significant military exercises, raises concerns about the potential for compromised operational security.
Police said the man was a former Chinese military serviceman who had operated a military supply store near Camp Humphreys since 2021. He told police he needed the information for his military equipment business, according to investigators. This claim points to the dual-use nature of many commercial enterprises in regions with significant military presence, where businesses can easily become conduits for espionage.
The man was charged Monday with aiding an enemy state and violating the Military Base and Installations Protection Act. The woman involved had been removed from her position by the time investigations began, indicating that the South Korean military is taking steps to mitigate potential security breaches.
The second case involves a Chinese man in his 60s who police said also previously served in the Chinese military. He was arrested on Monday on charges of aiding an enemy state and violating the Communications Secrets Protection Act after allegedly using a software-defined radio, or SDR, to intercept communications near Gunsan Airport in North Jeolla Province, about 110 miles (180 kilometers) south of Seoul. The use of SDR technology in espionage is not new; it allows individuals to listen to a wide range of radio frequencies, including those used by military and emergency services.
Gunsan Airport is a joint military and civilian airport near Kunsan Air Base, which is home to the US Air Force’s 8th Fighter Wing. This base plays a crucial role in the US military's ability to project power in the region and respond to threats. The presence of a former military operative in close proximity to such an installation raises alarms about the potential for intelligence gathering that could compromise operational security.
Police allege the man entered South Korea on a tourist visa several times from January 2024 and stayed about a week for each trip. His method of operation, which involved checking into a hotel near the airport and using a small SDR to intercept military communications, suggests a calculated approach to espionage, leveraging the tourist visa system to conduct surveillance without raising immediate suspicion.
During questioning, police said the man told investigators that “listening to military-related communications is my hobby.” This statement, while seemingly innocuous, could be interpreted as an attempt to downplay the severity of his actions. Officers are analyzing the content of the intercepted communications to determine whether the information was sent to China, a critical aspect of the investigation that could have serious implications for national security.
South Korea’s Defense Ministry and the United States Forces Korea declined to comment, a typical response in ongoing investigations, especially those involving national security. The lack of public commentary from these agencies may reflect the sensitive nature of the cases, as well as the potential diplomatic ramifications of acknowledging espionage activities, particularly when they involve foreign nationals.
The arrests of these two former military personnel serve as a stark reminder of the persistent threat of espionage in the region. As geopolitical tensions continue to rise, particularly between the US and China, incidents like these could have far-reaching consequences, affecting military strategies, international relations, and the overall security landscape in East Asia. The South Korean government, along with its US allies, will likely intensify efforts to bolster counterintelligence measures to protect sensitive military operations and information from foreign adversaries.
