Mainland Chinese law enforcement vessels, the Sansha Zhifa 301 and Sansha No 2, entered Taipei-claimed prohibited waters near Taiping Island on Thursday morning. Taiwan’s Coast Guard Administration (CGA) stated the vessels breached the 3.2-nautical-mile restricted zone before being driven away by Taiwanese authorities at 8:43 a.m.
What happened near Taiping Island?
The incident began at 8:28 a.m. on Thursday when the two mainland Chinese ships entered the 3.2-nautical-mile prohibited waters surrounding Taiping Island, also known as Itu Aba. According to the CGA, the vessels moved even closer to the 2.1-nautical-mile restrictive waters by 8:31 a.m.
Both vessels are managed by the southern Chinese city of Sansha in Hainan province. The CGA reported that its coast guard successfully drove the ships away from the area by 8:43 a.m. This marks the first time the CGA has reported mainland Chinese government vessels entering these specific restricted waters near Taiping.
Taiping Island is the largest natural feature in the Spratly Islands and is currently controlled by Taiwan.
How does this compare to the Pratas Islands incident?
While the Taiping Island encounter is a new development for these specific restricted waters, it follows a pattern of maritime activity in the region. Analysts have noted a distinction between the recent Taiping incursion and previous movements near other disputed territories.

Earlier this year, on June 5, a mainland Chinese coastguard ship entered the prohibited waters of the Pratas Islands, also known as the Dongsha Islands. While both incidents involve Chinese law enforcement vessels entering Taipei-claimed zones, the Taiping event is unique because of the specific restricted waters involved.
| Feature | Taiping Island Incident | Pratas Islands Incident |
|---|---|---|
| Date | Thursday (Recent) | June 5 |
| Vessel Type | Law Enforcement (Sansha) | Coastguard Ship |
| Status | First time in these restricted waters | Previous recorded incursion |
Why is Beijing targeting these specific waters?
Security analysts cited in the report suggest that Beijing’s movements around these islands are attempts to assert sovereignty through concrete action. These actions could potentially form the basis for Beijing to claim effective control over the waters in the future.
The timing of these maritime movements follows accusations from Beijing against Taiwan’s ruling Democratic Progressive Party. Beijing has criticized the party for its perceived inaction regarding Japan-Philippines maritime delineation talks. Those talks involve exclusive economic zones that could overlap with claims held by both Beijing and Taipei.
By increasing the presence of law enforcement vessels in proximity to Taiping Island, China may be testing the response capacity of Taiwan’s coast guard and establishing a physical presence that complicates future maritime governance.
Watch for the deployment of “law enforcement” vessels rather than purely military ones. These are often used in “grey zone” tactics to assert control without triggering a full-scale military conflict.
