It includes a map showing the area, as well as a file-photo of the frigate "Dong Guan" (东莞号), pennant number 560. This frigate belongs to the South Sea Fleet based in Sanya, Hainan.
The frigate reportedly got grounded there on 11 July at around 1900hrs. There are no injuries/casualties and PRC is organising a rescue.
In Chinese newscasts on this incident,
the frigate was reportedly conducting routine operations in the area, which involves chasing fishermen away.
If the PLA Navy is as strict on grounding as some of the western navies, the captain will be removed and never go to sea again.
