On June 9th at around 9 a.m., the Taiwan Coast Guard Administration's (TCGA’s) Third Patrol Distrct Command detected and tracked a suspicious vessel 6 nautical miles off the coast of Tamsui by Shalun Radar. They immediately reported it to the Eighth Coastal Patrol Corps of the Northern Branch, the Tamsui Second Fishing Harbor and Bali Inspection Stations to strengthen monitoring and response. When personnel from the Tamsui Second Fishing Harbor Inspection Station arrived on the scene, they found that the vessel's operator was a person from Mainland China, who was immediately arrested on the spot. He was taken back to the inspection station for further investigation to clarify the approach and purpose of his entry into Taiwan. Therefore, He was transferred to the Shilin District Prosecutors Office for investigation for violating the "Act Governing Relations between the People of the Taiwan Area and the Mainland Area" and the "Immigration Act."
　　In this case, the Shalun Radar operator locked onto the target 6 nautical miles off the coast of Tamsui but mistakenly identified it as a regular returning fishing vessel. Although the Tamsui Second Fishing Harbor and Bali Inspection Station personnel were notified for target identification, TCGA patrol boat was not dispatched in time to intercept and inspect the vessel. Additionally, after the Bali Inspection Station identified the vessel as not being a domestic fishing boat, they failed to immediately report it for investigation. There was indeed negligence on the part of the personnel involved, and the TCGA has held the responsible personnel accountable according to regulations.
　　This case was due to human misjudgments and negligence; the surveillance system did not miss the detection. Over the past decade (2014-2023), the TCGA has apprehended 119 Mainland China individuals for illegal entry and also, in this year, it has expelled 809 mainland China vessels trespassing in our prohibited and restricted water. Given the difficulties in identifying radar blips, to avoid similar misjudgments, the Taiwan Coast Guard Administration is introducing more technological aids, such as the "Island Coastal Smart Surveillance System" which combines radar with infrared thermal imaging, and gradually enhancing aerial and maritime patrols with drones. Efforts are also being made to ensure all domestic fishing vessels are equipped with AIS systems. Continuous personnel training and strengthened coordination with allied forces are being implemented to monitor and respond to maritime targets closely, ensuring the security of our national borders.
　　The Taiwan Coast Guard Administration stated that in the face of China's continuous harassment of gray zone tactics and cognitive warfare methods aimed at causing public panic. The Taiwan Coast Guard Administration appeal the publics to remain rational and calm, and to stand united in collectively responding to China's irrational behavior.
