The Diplomat reports the maiden patrol of China Coast Guard’s second monster 12,000 ton cutter.
The patrol was only 19 days, but no telling how quickly they will come out again.
When you want to play bumper boats, size really does matter and the Chinese have raised the stakes considerably. Meanwhile the Japan Coast Guard (and here) and South Korean Coast Guard also have some very large cutters.

A stripped down, ice hardened FFG hull wouldn’t even come close, but it might be affordable and doable should a favorable procurement environment ever again arise.
For a long time now I have wondered about ice strengthened slightly overpowered frigate size vessel for long range patrol work. The Russians have something like that and the Danes have the Thetis class.
