A picture taken on November 16, 2011 from a South Korean helicopter shows Chinese fishermen wielding sticks to stop an attack by South Korean coastguard commandoes armed with clubs aboard rubber boats during a crackdown on alleged illegal fishing in South Korean waters in the Yellow Sea off the southwestern coast county of Buan. South Korea’s coastguard mobilized 12 ships, four helicopters and commandoes for a special three-day crackdown on illegal fishing by Chinese boats this week.

“South Korea’s Coast Guard seized five Chinese vessels for allegedly fishing illegally in the country’s waters late last month, confiscating boats and deporting several crew members…The joint patrol’s 30 participating vessels and three aircraft waters were operating in the vicinity of Jeju Island from March 25-31, Korea JoongAng Daily reported.
“The country’s coast guard said that, on average, 300 Chinese vessels fish illegally in the country’s exclusive waters each day, with that figure dropping to an estimated 140 during periods of intensified crackdowns.”
As you can see from the photo above and below. This is not a new problem.

In many cases these encounters have become violent. The South Koreans have not been afraid to seized Chinese fishing vessels, but on the other hand they have not been successful in stopping large scale illegal fishing.

We need to be out there wherever this is happening and letting our allies, or any nation being bullied this way that it is alright for them to defend their rule of law. We need more gray zone capacity and we need enough we can export it en masse.
Start turning the encroaching Chinese fleet into FADs – Fish Aggregating Devices. That will send a clear and ironic message to the COMMUNIST CHINESE.
once they respond with violence against the authorities deadly force should be used..
South Korea and to a lesser extent Japan have the resources and will to do this. Philippines needs to build up the capacity and the will to take these measures. They’re not quite there yet but should be within the next few years.
Note the Kamov Ka-32S.
South Korea need ships with hardened strengthened hulls.
Perhaps an ‘area tug’ to pull or push the rafts?
PRC is skilful at treading along that ‘line’.
