A territorial dispute between China and Japan seems to be far from over. In the latest development, Beijing has sent four coastguard vessels to the disputed islands in the East China Sea. The move follows Beijing\'s mention of war after Tokyo approved a plan to shoot down Chinese drones if they fly over Japan\'s airspace. China has threatened to take firm countermeasures, if Japan fires on its drones. Japanese Prime Minister Shinzo Abe has accused China of trying to change the status quo in the region by force, adding that\'s why Tokyo is expected to take a leadership role over regional security issues. The relations between the two Asian powerhouses have been strained particularly over a group of disputed islands-- known as Senkaku in Japan and Diaoyu in China. Both countries claim sovereignty rights over the uninhabited resource-rich islands that are currently under Tokyo\'s control. Show Less >>
