Chinese Ambassador to the United Nations Wang Guangya on Wednesday required that Iran be more cooperative on its disputed nuclear program.

"According to what they announced, certainly it is not in line with what is required of them by the international community, including the IAEA resolution and the Security Council presidential statement," Wang told reporters at UN headquarter in New York.

"I hope the Iranians take note of the reaction (of the international community) and be more cooperative," he added.

Iranian President Mahmoud Ahmadinejad announced on Tuesday that Iran had successfully enriched uranium, but stressing that it did not want to seek to develop nuclear weapons.

Wang said China is concerned about the way in which things are developing.

China appeals to all parties concerned to exercise restraint, to act constructively, and not to take actions that might further aggravate the situation, he said.

He noted that diplomatic effort is still underway and military and other sanctions will not be helpful in the current situation.

"Diplomatic solution is the best way out of there," Wang added.
