Baird Maritime reports on an incident between Vietnamese and Indonesian fisheries protection vessels that resulted in the sinking of a Vietnamese fishing vessel in a disputed area of the South China Sea.
The Indonesian Corvette, KRI Tjiptadi (381), is a former East German Parchim class corvette like this one. It is about the size of a 210.
The South East Asian countries having disputes about their respective EEZs should really take it to the UN tribunal. The resulting decisions would ensure international recognition of their rights and leave China’s nine dash line claims in the trash bin.

Indonesia has again begun sinking vessels they have seized for fishing illegally in their waters. https://www.bairdmaritime.com/fishing-boat-world/regulation-and-enforcement/5379-indonesia-resumes-sinking-seized-iuu-vessels
I have to wonder if they cleaned them up and removed oil, fuel, etc. prior to sinking them. Maybe they will make nice reefs where more fish will reach maturity.
