China has claimed that foreign intelligence agencies are employing unusual methods to monitor its maritime regions, including the use of marine animals fitted with advanced sensors. The allegation was made by China’s Ministry of State Security, which warned of growing threats to national security in surrounding waters.
According to the ministry, a hidden intelligence battle is taking place beneath the ocean’s surface. Officials stated that foreign organizations are increasingly relying on sophisticated surveillance technologies to collect sensitive information from China’s coastal and maritime zones.
One of the most striking claims involves the use of so-called “spy turtles” and “spy fish.” Chinese authorities allege that these marine animals have been equipped with specialized sensors capable of gathering environmental and oceanographic data while moving naturally through the water.
The ministry said the devices can reportedly collect information such as water temperature, salinity levels, and ocean current directions. This data is believed to be transmitted in real time through satellite communication systems to external operators located abroad.
Chinese officials argue that such activities could provide valuable intelligence about maritime conditions, potentially affecting national security and strategic interests. The ministry emphasized that underwater surveillance technologies are becoming increasingly advanced and difficult to detect.
Despite the serious nature of the allegations, the statement did not identify any specific country, intelligence agency, or organization responsible for the reported activities. Authorities also did not reveal where the alleged sensor-equipped animals were discovered or whether any devices had been recovered.
The claim has drawn attention due to its unusual nature and highlights China’s ongoing concerns about foreign surveillance efforts in the region. As competition over maritime security and technological intelligence continues to grow globally, underwater monitoring methods are expected to remain a significant area of focus for governments and security agencies.
