Things just got a whole lot more serious in the East China Sea.
Last week, Japanese officials announced a Chinese naval vessel had locked its weapons-targeting radar on a Japanese military helicopter and naval vessel in separate January incidents. This new escalatory step in Chinese behavior is one in a series of many, prompting Japan to respond. The tit-for-tat spiraling brings China and Japan closer to one mistake away from potential armed conflict. The two sides need to talk, but questions of sovereignty over a group of disputed islands should be the last thing on their agenda. Instead, Beijing and Tokyo need rules to regulate the interaction of their coast guards, navies, and other vessels and aircraft to prevent a mistake becoming a pretext for conflict.
The dispute between Beijing and Tokyo is not new. Called the Senkaku Islands in Japan and the Diaoyu Islands in China, the dispute involves a group of uninhabited islands controlled by Japan in the East China Sea but claimed by China (and Taiwan). The situation was fairly calm until spring 2012 when then Tokyo governor Shintaro Ishihara made moves to buy three of the islands with a plan to build on them. Because this contradicts central government policy of no landing, no development, then premier Yoshihiko Noda blocked Ishihara by buying them with central government resources instead.
Not surprisingly, Noda’s move angered China. In addition to setting off large-scale, violent and destructive anti-Japanese protests throughout China, it initiated a now near-daily presence of Chinese ships and planes near the islands. Much to the detriment of regional peace and stability, China’s moves have increasingly become bolder, forcing Japan to respond.
At first, Chinese presence near the disputed islands was limited to patrol ships from the maritime and fisheries agencies in nearby waters, mirrored by Japanese coast-guard ships. Then China escalated the situation in December by sending a maritime-surveillance plane into Japanese airspace, forcing Japan to scramble fighter jets. Last month, China upped the stakes by sending a military aircraft into Japanese airspace, forcing Japan to once again scramble jets, which were met—for the first time—by scrambled Chinese jets. Japan responded by announcing it was considering authorizing the firing of warning shots at Chinese planes that enter its airspace. China answered with its most recent provocation of locking onto Japanese military assets with weapons-targeting radar.
This tit-for-tat escalation is worrisome. As China becomes bolder and more provocative, Japan is meeting the assertiveness in-kind. Yet, one mistake could be right around the corner. One need only remember the 2001 EP-3 incident off the coast of Hainan, China, in which a Chinese J-8 fighter jet collided with a US Navy EP-3. The Chinese pilot was killed and the EP-3 was forced to land on Hainan where the crew was detained and interrogated by Chinese officials until the US government made a statement regarding the incident. At root was China’s aggressive monitoring of U.S. presence in airspace over China’s exclusive economic zone, International law says all states enjoy freedom of navigation and overflight in exclusive economic zones, but China disagrees. It took skillful diplomacy to end the confrontation and secure the return of the US servicemen and women.
It is hard to imagine an East China Sea version of the EP-3 incident, one in which Chinese are killed and Japanese are detained, would end as quietly as the 2001 U.S.-China incident. The volatile mix of nationalism and historical grievances in China, combined with a Japanese populace more willing to see their leaders take a hard line with China, means a mistake on any scale has the potential to spiral out of control.
