Coping with “gray zone” situations has in recent years become the core security challenge for Japan. Since September 2012, Beijing has been challenging Japan’s sovereign control of the Senkaku Islands by regularly sending law-enforcement vessels into Japanese territorial waters and contiguous zones.

Beijing sends civilian or paramilitary forces to change facts on the ground while daring the targeted country to use force to stop these activities. These incursions, which do not amount to an armed attack, are blurring the line between crime and defense, law enforcement, and military activities.

In August, an armada of 230 Chinese fishing boats, accompanied by 7 Chinese Coast Guard (CCG) vessels, was spotted near the Senkakus. This could have led to a nightmare scenario for Tokyo in which the disputed islands are seized by Chinese armed fishermen. Such a situation could quickly escalate with the arrest of the intruders at sea by the Japan Coast Guard (JCG) or on land by the police forces, followed by the deployment of Chinese naval vessels to rescue its citizens. The Japan Maritime Self-Defense Forces (JMSDF) could then be deployed on site, on the request of the Cabinet Office, only with limited authorization to use force (law-enforcement powers). This chain of events would create a tense standoff between JMSDF and Chinese naval vessels with a high risk of developing into a military incident. The dilemma for Japan would be to choose between being the first side to use force to displace the intruders and leaving them alone with the risk of Beijing claiming actual control of the islands. In this kind of scenario, a clear division of roles between the JCG and JMSDF, with the early involvement of the latter, would ensure a greater deterrence effect and a swifter and consistent response in case of an intrusion.

Asia is a nerve center for multiple global economic, political and security challenges. The Center for Asian Studies provides documented expertise and a platform for discussion on Asian issues to accompany decision makers and explain and contextualize developments in the region for the sake of a larger public dialogue.

The Center's research is organized along two major axes: relations between Asia's major powers and the rest of the world; and internal economic and social dynamics of Asian countries. The Center's research focuses primarily on China, Japan, India, Taiwan and the Indo-Pacific, but also covers Southeast Asia, the Korean peninsula and the Pacific Islands. 

The Centre for Asian Studies maintains close institutional links with counterpart research institutes in Europe and Asia, and its researchers regularly carry out fieldwork in the region.

The Center organizes closed-door roundtables, expert-level seminars and a number of public events, including an Annual Conference, that welcome experts from Asia, Europe and the United States. The work of Center’s researchers, as well as that of their partners, is regularly published in the Center’s electronic journal Asie.Visions.
