THE SECURITY DIAMOND OF JAPAN, INDIA, AUSTRALIA, AND AMERICA
Peace, stability, and freedom of navigation in the Pacific Ocean are inseparable from peace, stability, and freedom of navigation in the Indian Ocean. Developments affecting each are more closely connected than ever. Japan, as one of the oldest sea-faring democracies in Asia, should play a greater role in preserving the common good in both regions.
Yet, increasingly, the South China Sea seems set to become a "Beijing Lake," which analysts say will be to China what the Sea of Okhotsk was to Soviet Russia: a sea deep enough for the People's Liberation Army's navy to base their nuclear-powered attack submarines, capable of launching missiles with nuclear warheads. Soon, the PLA Navy's newly built aircraft carrier will be a common sight - more than sufficient to scare China's neighbors.
That is why Japan must not yield to the Chinese government's daily exercises in coercion around the Senkaku Islands in the East China Sea. The ongoing disputes in the East China Sea and the South China Sea mean that Japan's top foreign-policy priority must be to expand the country's strategic horizons.
Japan is a mature maritime democracy, and its choice of close partners should reflect that fact. I envisage a strategy whereby Australia, India, Japan, and the US form a diamond to safeguard the maritime commons stretching from the Indian Ocean region to the western Pacific. I am prepared to invest, to the greatest possible extent, Japan's capabilities in this security diamond.
