 Well, on November 23rd, Chinese authorities announced that they were mapping, for the first time, an air defence identification zone. Now, air defence identification zones are not illegal, are not against international practice. In fact, there's quite a number of countries worldwide that have some, including some of China's neighbours, South Korea and Japan. So, where is the main issue? What is the main problem? Well, it is on two different main levels. From the point of view of procedures, what the Chinese are asking is beyond the borders of international standard practice. They're asking every aircraft flying into this air defence zone to provide the flight plans and remaining on standby and providing communication about their movements. Which is something that, in other air defence identification zones, is only applied to aircraft that are bound to the country in which they are flying. So, in this respect, there is a different sort of practice that has been adopted by the Chinese. And what would be the possible solution? Well, the current situation is one in which what we're seeing unfolding is a political game. A game in which the maritime and air spaces of this China Sea are used as an arena where the balance between two most important regional actors, Japan and China, are redefining their relationship. As such, the main long-term solution will have to find its place in the realm of politics. But what do we do in the meantime? In the meantime, there are some practical steps that should be taken in order to avoid inadvertent escalation. In this respect, both in terms of behaviour as well as behaviour in the air, the two countries should try to hold high-level meetings to discuss mechanisms of communication, the establishment of hotlines, as well as start thinking about the elements that bring them together. The importance of using the maritime and air spaces and therefore considering measures that will make safer to do so, including activities concerning search and rescue operations, as well as the coordination of flight paths.
