Pretty much so. They must have some intel about that and from what Japanese CG reported from the last standoff near Senkaku's there were 'fishermen' coming and going from Chinese CG cutters to fishing boats. They work in a similar way that North Koreans do it seems. I'm not saying that's bad but rises some doubts.
Hmm, so for the CCG, in return, the Japanese fishers (and Whalers) should be fair game then?
Greenpeace should be satisfied.
