BEIJING -?China's newly-established Air Defense Identification Zone (ADIZ) will not cause regional tension, Foreign Ministry spokesman Qin Gang said on Friday.

"China's ADIZ over the East China Sea is not aimed at any specific country nor target. It's absolutely a measure designated to exercise the right of defense effectively," Qin told a regular press briefing.

It has not influenced the flight order and normal fly-over in the air since its establishment last Saturday, Qin said.

"If some worry has emerged about the situation, it's agitated by some individual countries," he said.

Qin refuted Japan's criticism on China's ADIZ, blaming such action as "unreasonable and out of ulterior motives."

Japan's own ADIZ was established in 1969 and has expanded twice since then.

"Would the Japanese side tell other countries, does it have ADIZ? Has it negotiated with other countries while it established and enlarged its ADIZ? How large is its ADIZ?" Qin said.

He reiterated China's adherence to the road of peaceful development.

"Even if some territory and maritime disputes exist between China and some other countries, we want to settle them through peaceful means via friendly negotiation," he said.

Answering a question about the overlapping area between Chinese and Japanese ADIZs, Qin said China wants to enhance communication to jointly preserve flight security.

On the disputes about the Diaoyu Islands, Qin said the current difficulty is that the Japanese side has always shunned substantial talks with China.

"We hope the Japanese side will not only talk about dialogue, but do so with tangible efforts," he said.
