Again, it's worth noting that this is not the first time this has happened or a new step up in how far the Chinese are willing to push.

The August 3 edition of the Mainichi Daily News, a Japanese newspaper, reported on a June 23 confrontation over a fleet of 10 Chinese fishing vessels operating without permission in Indonesia's EEZ. A stand-off over the Indonesian navy's seizure of a Chinese fishing boat almost got out of control when a Chinese "fishery management vessel" – which was actually a repurposed heavy gunboat – threatened to fire on the Indonesian navy patrol boat. According to the article, the fishery management vessel pointed its large-caliber machine gun at the carbon-hulled Indonesian craft, at which point the outgunned patrol boat released the errant Chinese trawler. The article says that a similar episode occurred in May, with the same large Chinese warship having likewise successfully threatened an Indonesian naval patrol that was detaining an illegal Chinese fishing boat.
