In recent years，with the rapidly decline of inshore fishery resources，all the countries have strengthened their consciousness to protect their ocean rights. More and more fisher disputes and incidents occur between China and neighbor countries. Non-traditional security has become a new perspective to observe the Sino-ROK relations. The fishery disputes caused heavy losses not only to the fishermen of the two countries，but also caused serious negative effect to the development of bilateral relations. What’s more，some great powers make use of this chance to involve China’s neighbor issues. Therefore，both governments should coordinate with each other to solve the fishery disputes，and push the Sino-ROK relations forward into the future.
