A North Korean patrol boat crossed briefly into South Korean waters Sunday to seize a Chinese fishing boat that had been illegally fishing in the North.
The patrol boat sped nearly two kilometers into the southern section of the Yellow Sea, notifying the South Korean navy that it was tracking an illegal fishing boat.
South Korea's Joint Chiefs of Staff said in a statement, the South Korean navy radioed a warning about the border crossing, and 25 minutes later the patrol boat crossed back into North Korean waters.
The Yellow Sea, on the western side of the Korean Peninsula, has been the scene of deadly North and South confrontations in recent years. The two sides have established a radio protocol to prevent future clashes.
