Sept. 29 will mark 40 years of normalized diplomatic relations between China and Japan, two countries that spent much of the 20th century in mutual enmity if not at outright war. The anniversary comes at a low point in Sino-Japanese relations amid a dispute over an island chain in the East China Sea known as the Senkaku Islands in Japan and Diaoyu Islands in China.
These islands, which are little more than uninhabited rocks, are not particularly valuable on their own. However, nationalist factions in both countries have used them to enflame old animosities; in China, the government has even helped organize the protests over Japan's plan to purchase and nationalize the islands from their private owner. But China's increased assertiveness is not limited only to this issue. Beijing has undertaken a high-profile expansion and improvement of its navy as a way to help safeguard its maritime interests, which Japan -- an island nation necessarily dependent on access to sea-lanes -- naturally views as a threat. Driven by its economic and political needs, China's expanded military activity may awaken Japan from the pacifist slumber that has characterized it since the end of World War II.
An Old Conflict's New Prominence
The current tensions surrounding the disputed islands began in April. During a visit to the United States, Tokyo Gov. Shintaro Ishihara, a hard-line nationalist known for his 1989 book The Japan That Can Say No, which advocated for a stronger international role for Japan not tied to U.S. interests or influence, said that the Tokyo municipal government was planning to buy three of the five Senkaku/Diaoyu islands from their private Japanese owner. Ishihara's comments did little to stir up tensions at the time, but subsequent efforts to raise funds and press forward with the plan drew the attention and ultimately the involvement of the Japanese central government. The efforts also gave China a way to distract from its military and political standoff with the Philippines over control of parts of the Spratly Islands in the South China Sea.
