After returning as Japanese prime minister, Shinzo Abe has been acting "tough", claiming that Japan enjoys an advantage in the Diaoyu Islands dispute and launching "attacks" on China on the diplomatic front.

Tensions have escalated in the East China Sea because of the Diaoyu Islands dispute and pose an unprecedented challenge to peace and stability in Northeast Asia, and Japan is squarely responsible for that.

The previous Japanese government, under the Democratic Party of Japan, played out the farce of "nationalizing" the Diaoyu Islands. And now Abe's Liberal Democratic Party government refuses to recognize the dispute over the Diaoyu Islands. It is not only refusing to negotiate to resolve the dispute, but also challenging China's territorial sovereignty and trying its patience.
