Increase in ghosts ships off Japan west coast

I did a post about this a couple of months ago representing Joshua Stantons good research on the cause of the ghost ships off Japans coast. see below link.

this one came in from the DailyNK reporting that the number of north Korean shipwrecks have increased.

They will be doing a five part series on this and will be interesting to see what conclusion they come to.
As mentioned in the previous post, Stanton concluded that the NK regime had sold fishing rights to China forcing the average fisherman further out to sea to get a decent catch.
i'm guessing that still holds judging from the recent increase in wrecks found.
Chinas big trawlers would be sucking everything up in the region
