How blue crabs, and the sea they inhabit, could make or break peace on the Korean peninsula
Mark J. Valencia says the agreement between North and South Korea to establish a maritime peace zone would go some way towards preventing conflicts, especially during peak fishing periods

If and when the talks get back on track they might initially focus on a little noticed detail of the declaration: an agreement to “devise a practical scheme to turn the areas around the Northern Limit Line in the West [Yellow] Sea into a maritime peace zone in order to prevent accidental military clashes and guarantee safe fishing activities”.
The competition for the valuable seafood coincides with a spike in violent incidents there. In 1999, four North Korean patrol boats escorting a group of fishing boats crossed the Northern Limit Line. A firefight ensued that left one North Korean vessel sunk, five patrol boats damaged, 30 sailors killed and 70 wounded. There have been several subsequent violent and dangerous incidents, in 2002, 2004 and 2009. Most began with North Korean fishing boats and patrol vessels crossing the Northern Limit Line.
