It is clear that the Chinese Coast Guard is engaging in AIS spoofing to mislead the international community, confuse authorities, and instigate public concern. It is particularly ironic that maritime safety, a fundamental responsibility of any coast guard organization, is compromised by China’s disregard for the International Convention for the Safety of Life at Sea (SOLAS), especially the mandatory AIS requirements outlined in Chapter V for certain vessels.
Analyzing the 60-day track of CCG-21543, it becomes evident that this vessel could not realistically navigate those routes. It is highly probable that they are exploiting the AIS signals of other vessels for their spoofing activities. In the Philippines, it seems likely that they are utilizing dredgers to facilitate this AIS manipulation.
