Joint development，an effective method to reduce the tensions pertaining to the delimitation of the continental shelf, is often carried out in the continental shelf areas with overlapping claims. The area to be selected for joint development between China and Japan should be the sea areas between the maximum water depth of the Okinawa Trough and the so-called median line proposed by Japan. The “Consensus on the East China Sea”，a political will reached between the governments of China and Japan, is the foundation for joint development in accordance with international law. While the participation of Japanese enterprises in cooperative development of the Chunxiao Oil and Gas Field is a commercial arrangement made in accordance with Chinese law，which is not a joint development in the sense of international law and has no relevance to the Understanding between China and Japan on Joint Development of the East China Sea
