TAIPEI — Taiwan has expanded an investigation into a suspected Chinese espionage network following the conviction of two former military personnel accused of passing military secrets and attempting to recruit fellow service members, raising fresh concerns about the vulnerability of Taiwan’s armed forces to covert intelligence operations.
The investigation, centered in southern Taiwan, now involves more than 20 persons of interest, including several serving army captains, according to sources cited by the Taipei Times. Authorities are examining whether the suspected network attempted to systematically identify military personnel who could be pressured or recruited to provide sensitive information.
The developments come after the Kaohsiung branch of Taiwan’s High Court convicted two former sergeants on espionage and corruption-related charges.
An ex-Army sergeant surnamed Fang was sentenced to 10 years and four months in prison, while former Air Force sergeant Huang received a seven-year sentence. The verdicts can still be appealed.
Military secrets allegedly passed to China
According to the court findings reported by the Taipei Times, Fang and Huang were accused of working with the Wo Long Hui, or “Crouching Dragon Society,” an organization described as having links to Chinese intelligence.
The two were found guilty of passing military secrets to China and attempting to recruit other Taiwanese service members into the network.
Fang was also accused of recording a video declaring surrender after being recruited, according to the report.
The investigation has raised particular concern because authorities believe the suspected network may have targeted military personnel experiencing financial difficulties.
Sources told the Taipei Times that the organization allegedly provided relatively small loans to financially vulnerable officers, allowing debts to accumulate before using the resulting financial pressure as leverage for recruitment. Investigators are also examining alleged loyalty oaths, payments for intelligence and rewards for recruiting additional members.
Importantly, authorities have not established that everyone currently under investigation stole secrets or acted on behalf of China. The investigation is ongoing, and the allegations against individuals who have not been charged remain unproven.
Concerns extend beyond two convicted soldiers
The latest case is not an isolated espionage investigation.
In April, Taiwan’s Central News Agency reported that prosecutors in Kaohsiung had indicted 10 people in another national-security case involving allegations that an overseas-linked organization sought to recruit current and former Taiwanese military personnel, including allegedly pressuring them to record videos supporting unification with China and to obtain military secrets.
Taiwan News also reported in April that the Taiwan High Court had convicted six current and former military personnel in a separate case involving allegations that sensitive military and government information was collected and passed to China-linked operatives.
In another case reported this month, prosecutors indicted a 34-year-old Taiwanese soldier surnamed Chiang, alleging that he provided confidential military electronic records to a China-linked organization in exchange for money.
Prosecutors said Chiang was initially approached after seeking loans online because of financial difficulties. He allegedly received nearly NT$600,000 in payments and accessed military systems to obtain confidential records. He faces charges under Taiwan’s National Security Act and Anti-Corruption Act.
Financial pressure emerges as a recurring recruitment tactic
The cases have highlighted a potentially significant vulnerability: personal financial problems.
Taiwanese prosecutors have previously described alleged recruitment efforts in which individuals facing financial difficulties were approached with money, loans or other incentives before being asked to provide information or assist intelligence operations.
In the latest investigation, sources cited by the Taipei Times said investigators are examining financial transactions and trying to determine how Chinese intelligence operators identified military personnel considered vulnerable to recruitment.
The concern is particularly serious because military personnel can have access to information that could reveal operational procedures, unit structures, capabilities or other sensitive details.
Some suspected targets were reportedly rising officers
The investigation has also drawn attention because some of the military officers reportedly under scrutiny were not considered marginal or disgruntled personnel.
According to sources cited by the Taipei Times, several were described as rising military officers with strong academic records and good service histories.
Some allegedly shared educational backgrounds, including attendance at Taiwan’s military preparatory and academy systems. Sources also said Chinese intelligence may have approached some officers relatively early in their careers.
That possibility has intensified concerns within Taiwan’s security establishment because it suggests that suspected intelligence recruitment may not be limited to individuals already alienated from the military.
The bigger picture: Taiwan is strengthening its defenses
The espionage investigations come as Taiwan faces broader pressure from China and prepares to significantly increase military spending.
Taiwan’s government has proposed a record NT$1.1225 trillion defense budget for 2027, an increase of about 18 percent from the previous year and more than 3 percent of GDP, according to Reuters.
President Lai Ching-te has described the additional defense spending as an investment in peace and national security. The proposed funding includes modernization efforts involving drones, missiles and other asymmetric capabilities.
Taiwan’s military preparations have also intensified amid continued Chinese military activity around the island.
Reuters reported on Aug. 21 that Taiwan’s coast guard had warned and monitored a Chinese research vessel operating in sensitive waters west of Taiwan, describing the incident as part of a broader pattern of activity that Taipei views as potential gray-zone pressure.
Why the latest spy investigation matters
The expanding investigation illustrates that Taiwan’s security challenge extends beyond traditional military confrontation.
Rather than relying solely on overt military pressure, intelligence operations can attempt to exploit personal relationships, financial problems and access to sensitive information.
For Taiwan, the immediate challenge is determining how extensive the suspected network is, whether additional military personnel were successfully recruited and whether classified information was transferred beyond the cases already identified.
For now, authorities have not publicly established that all people being investigated participated in espionage. But the growing number of cases involving current and former military personnel has placed counterintelligence and internal security under renewed scrutiny.
The latest convictions may therefore be only one piece of a much larger investigation — and authorities’ next moves could reveal just how deeply the suspected recruitment network reached into Taiwan’s military.
