Japan's claim over China's Diaoyu Islands is yet another attempt to break the international order established after World War II, and it is proof of the Japanese right wing's ambitions to rebuild the country as a military power, experts said on Saturday.

Wu Enyuan, a researcher at the Chinese Academy of Social Sciences, said Japanese right-wingers have for decades attempted to deny the order established after the last war.

"These attempts may produce new destabilizing factors for the Asian-Pacific region and the international order," he said at a global conference on World War I and World War II in Beijing.
