NEW DELHI — Japan may have created the impression of having buckled under China's pressure by releasing the Chinese fishing trawler captain. But the Japanese action helps move the spotlight back to China, whose rapid accumulation of power has emboldened it to aggressively assert territorial and maritime claims against its neighbors, from Japan to India.

Having earlier preached the gospel of its "peaceful rise," China is no longer shy about showcasing its military capabilities and asserting itself on multiple fronts. While the Chinese leadership may gloat after forcing Tokyo to climb down and release the captain, the episode — far from shifting the Asian balance of power in Beijing's favor — has only shown that China is at the center of Asia's political divides.

China's new stridency in its territorial and maritime disputes with its neighbors has helped highlight Asia's central challenge to come to terms with existing boundaries by getting rid of the baggage of history that weighs down a number of interstate relationships. Even as Asia is becoming more interdependent economically, it is becoming more divided politically.
