Resolving the phony battle of the competing ADIZs

Author: Sourabh Gupta, Samuels International

On 23 November, China announced the establishment of its East China Sea Air Defence Identification Zone (ADIZ). The policy, its announcement, and the prompt and selective nature of its implementation bear many of the quintessential hallmarks of Chinese statecraft.In this Sept. 2, 2012 photo, the survey ship Koyo Maru, left, chartered by Tokyo city officials, sails around Minamikojima, foreground, Kitakojima, middle right, and Uotsuri, background, the tiny islands in the East China Sea, called Senkaku in Japanese and Diaoyu in Chinese.

The policy is intended to deliver a shock to the adversary — that being Japan in this case. Although Beijing avers that the ADIZ was drawn with no target country in mind, the zone only marginally overlaps with Taiwan’s and South Korea’s ADIZs (the Korean ADIZ overlap area has since been enlarged by Seoul). No Chinese military aircraft has yet flown into these overlapping zones. By contrast, Chinese surveillance aircraft have flown across the breadth and (most of the) length of the overlapping portion of Tokyo’s ADIZ.

The policy is intended to be a political rejoinder (in an escalating series) to an immediate provocation — the alteration of the status quo by the Noda government’s private purchase of three Senkaku/Diaoyu islands in September 2012. The purchase was officially frowned upon by even Japan’s chief ally, the United States. That Chinese coast guard vessels have also asserted an operational presence in the Senkaku/Diaoyu territorial sea 72 times since the islands’ purchase suggests that Beijing will persist in fanning the flames of a fire that it did not light.

The Abe government would be well-advised to not pursue the proposed ‘maritime communications mechanism’ arrangement for the time being, given the frigid state of bilateral ties. It isn’t a coincidence that ground was broken towards devising this arrangement during the Fukuda and Hatoyama years — the only two Japanese governments perceived as Beijing-friendly over this past decade. As China’s recent Border Defence Cooperation Agreement with India bears out, a period of political quiet and trust needs to be engendered prior to resumption of high-level discussions on confidence-building measures.

China’s policy is intended to provoke a reaction, and a self-defeating one at that. And Japan, by barring its airline companies from notifying Chinese authorities of flights traversing the new zone’s overlapping portion —  even as American, South Korean and Taiwanese commercial air-traffic are complying — has played into China’s hands. Over time, its relative isolation on this point will only become clearer. The Abe government’s instruction is also inconsistent with Japan’s own notification policy. Tokyo’s ADIZ overlaps with the Taipei Flight Information Region (FIR), much like China’s ADIZ overlaps with the Japanese FIR. And like China, Japan too has required since 2009 that all commercial traffic traversing the overlapping section to onward destinations in north-eastern China notify their flight plans to Japanese authorities.

The post-September 2012 Chinese pressure on the Senkaku/Diaoyu has ironically been a blessing in disguise for Japan’s other neighbours, as Tokyo has played nice to deflect the possibility of a hostile united front on jurisdiction-related matters. Seoul has recently accomplished what it had unsuccessfully sought since 1963: Tokyo’s acquiescence to the enlargement and overlap of its ADIZ; and, Taipei, what 16 rounds of talks with Tokyo since 1996 had failed to achieve: a jointly administered fisheries zone in the Senkaku/Diaoyu waters.

China’s policy is intended to fully comport with international practice — albeit with an element of the extra-legal. An ADIZ is set up under a given nation’s domestic laws, not international law, and serves as a defensive perimeter beyond territorial airspace to monitor incursions by suspicious aircraft. It does not connote claim to territory; that claim exists separately — much like Japan’s claims to Dokdo/Takeshima and the Kuril Islands/Northern Territories exist separately.

China’s Survey and Mapping Law of 2002, promulgated in the wake of the 2001 EP-3 incident, identifies the limits of Beijing’s sovereignty in the skies to its 12 nautical mile territorial airspace. As such, the unspecified ‘defensive emergency measures’ in China’s ADIZ notification is for all practical purposes envisaged to intercept and escort suspicious, non-military air targets beyond the national airspace that are deemed to be a threat during peacetime. That said, incorporating the skies over the Senkaku/Diaoyu islands within its alert zone is a show of exceedingly poor form on Beijing’s part. No other country in the region extends its ADIZ to cover disputed territory that it fails to effectively control.

The policy treads along a furrowed path long ploughed by adversaries — timed to unsettle the strategic environment. It is inconsistent of Japan to decry China’s notification for its unilateralism and abruptness when its own ADIZ (along with that of South Korea and Taiwan) was notified without prior consultation in the early-1950s. Tokyo’s ADIZ does not limit itself to the median line in the East China Sea either. In 2010, Japan’s modification of the Japan-Taiwan ADIZ separation line over Yonaguni Island was brought into force on roughly two days’ notice — similar to that which Beijing allegedly provided to Seoul (of course, Tokyo was left uniformed).

As to China’s timing, the extension of PLAAF patrols beyond the territorial sea in the Taiwan Straits (following Lee Teng-hui’s presidential election in 1996) and up to the median line in 1999 (following Lee’s ‘two states’ comment) suggests that a political — not military — calculus of deterrence informs China’s ADIZ policy.

Going forward, three things need to happen.

Foremost, it is imperative that all non-commercial, manned Chinese aircraft refrain from entering the territorial airspace over the Senkaku/Diaoyu islands. The danger and fallout from a collision is real and present. Equally, the Abe government must vigilantly ensure that the status quo on the islands is not disturbed as it enters an active phase of national security policymaking, which includes solidifying the defence of its outlying territories. Second, China must make every effort to establish protocols with neighbouring militaries on ADIZ enforcement — either tacitly on the lines of its practices with the Taiwanese air force in the Straits or explicitly on the lines established mutually between the South Korean and Japanese militaries. Finally, when China does notify its ADIZs in the Yellow and the South China Seas to protect its (current and future) home-ported aircraft carriers, China must make every effort to consult with adjacent and interested littorals.

Ultimately, it rests on Abe’s shoulders to make a best endeavour effort towards admitting a dispute or, at minimum, admitting the contestable legitimacy of Beijing’s claim to the Senkaku/Diaoyu islands if this latest chapter of Sino-Japanese tensions is to be closed.
