Were Beijing to actually enforce for good its aerial jurisdiction around the Diayou islands, that would be the beginning of the breach of this aquatic Hadrian's wall. For the moment, though, ADIZ is a message to Washington, part of the much-vaunted xinxing daguo guanxi -- the "New Type of Great Power Relations" being implemented slowly but surely by President Xi Jinping.
Beijing may be right on principle and certainly does want to create facts on the sea. What happened was essentially a PR disaster -- an inability convincingly to "sell" the ADIZ to world public opinion. Absolutely nothing will convince any Chinese administration that this is not about Japan encroaching upon a territory and sphere of sovereignty that have been Chinese for centuries.
Instead of the usual ritualistic pilgrimages to revere "heroes" in shrines accused of committing hair-raising massacres, Tokyo could easily defuse the problem by admitting to its appalling imperial adventures in Asia. Tokyo could also redefine its role in Asia by behaving like an Asian power -- and not some obedient Western appendix, as it's perceived by millions across the continent, and not only by the Chinese.
