China brushes off Japan's Okinawa protest as experts call it move to seize Diaoyus
Tokyo lodges diplomatic objection to Chinese scholars' assertions on island's ownership

China has dismissed a diplomatic protest by Japan over a commentary in a state-run publication that challenged Tokyo's ownership of Okinawa, home to major US bases.
The latest angry exchange could further strain tense relations between Asia's two largest economies, which are involved in a stand-off over a group of uninhabited islands in the East China Sea, called the Senkakus in Japan and the Diaoyus in China.

The People's Daily, the Chinese Communist Party's mouthpiece, published a commentary on Wednesday, which said ownership of the Ryukyu islands - of which Okinawa is the biggest - should be re-examined, prompting Japan to lodge the diplomatic protest.
"China cannot accept Japan's so-called negotiations or protests," Foreign Ministry spokeswoman Hua Chunying said yesterday.
"The relevant scholars' academic articles reflect attention and research paid by China's populace and academia to the Diaoyu Islands and related historical problems," Hua said.
