Senkakus should not be put under Japan-U.S. security pact: China

China on Wednesday expressed strong opposition to U.S. President Barack Obama's view that a group of islands at the heart of a fierce dispute with Japan falls under the scope of Washington's security treaty with Tokyo.

"We are firmly opposed to putting the Diaoyu Islands under the U.S.-Japan treaty," Foreign Ministry spokesman Qin Gang told a press conference, referring to the Chinese name for the Japanese-controlled Senkaku Islands.

Qin said the treaty is "a bilateral arrangement forged in the Cold War era and it should not undermine China's territory and legitimate rights and interests."

He also criticized Japan for trying to play a bigger role in regional security with the United States.
