China steps up naval patrols in disputed islands with Japan

China has stepped up its naval patrols in the waters of the disputed Sankakus islands (Diaoyu islands) under the administrative control of Japan in the East China Sea.The move could anger Japan as both countries doggedly trying to enforce the claims over the uninhabited islands. China is saying that it is conducting such patrols on a regular basis in its territorial waters.These islands were under the control Japan since 1895 till 1945 after they went under administration control of United States as part of the Ryukyu Islands till 1972. They are strategically located close to key shipping lanes and rich fishing grounds, and there may be oil reserves in the area. Since Japan asserted its control by nationalising Sankakus islands in 2013 to step up its claims, China has started its naval patrols in the disputed waters.
