How China-Japan relations will benefit from new crisis management agreement

Zhou Bo says the hard-won air and maritime agreement signed between China and Japan is an indication of the vulnerability of relations between the two Asian powers, and calls on both to build on this good start

Premier Li Keqiang’s official visit to Japan last week, the first by a Chinese premier since the Japanese government “bought” the Diaoyu Islands in 2012, saw one of the most significant outcomes – the signing of a crisis management agreement on which the two sides spent 10 years of on-and-off negotiations.

The agreement comes as a huge relief. Officially described as a “maritime and air liaison mechanism between the defence ministries of China and Japan”, it is meant to defuse tensions arising out of close encounters between Chinese and Japanese military aircraft and naval vessels. Although there is yet to be an incident, the chances of dangerous encounters are on the rise with each passing year. 

Xi likely to make official Japan visit as two sides try to mend fences

In 2013, China announced the establishment of an air defence identification zone, which overlaps slightly with Japan’s own zone. While Japan strongly protested against the move, it is not legally prohibited.

An air defence identification zone is an airspace that extends beyond a country’s territory to give the country more time to respond to possibly hostile aircraft. Since the first such zone was established by the United States in 1950, over 20 countries in China’s periphery, including Japan, South Korea, North Korea, India, Pakistan and Russia, have established their own zones. 

Japan’s zone, created by the US after the second world war, is much larger than Japanese territory and extends to within 130km of China’s coast. Thus, Japan’s hysterical reaction to China’s much smaller zone was strange.
