On the one hand, China has stepped up its emphasis on sovereignty, especially concerning its territorial dispute with Japan over the Diaoyu Islands (or the Senkakus, as they’re known in Japan).
Beijing has streamlined its various maritime agencies to make them more efficient and better coordinated, and it keeps sending government vessels to the area to demonstrate its jurisdiction over this region.
More recently, it announced a new Air Defense Identification Zone (ADIZ) in the East China Sea to assure its sovereign security over territory, territorial water and space in the ADIZ.
On the other hand, China has attached more importance to its peripheral stability. Despite its earlier skirmish over Ladakh with India in May, it cut a border defense co-operation agreement with New Delhi, to avoid mutual tailing between their patrols in border areas where there is no common understanding of the line of actual control.
