China has welcomed this week's talks between Iran and world powers on Iran's nuclear development, saying they were "positive and beneficial."
"The dialogues helped all parties deepen mutual understanding," said Chinese Foreign Ministry spokeswoman Jiang Yu on Thursday.
Talks on the Iranian nuclear issue resumed in Geneva on Monday, attended by Iran's chief nuclear negotiator Saeed Jalili and EU foreign policy chief Catherine Ashton on behalf of the five UN Security Council permanent members plus Germany.
China expected all parties to stick to the direction of settlement by diplomatic negotiation, Jiang said.
China urged all parties to establish mutual trust, seek common ground and push for constant progress in the dialogue process in the spirit of cooperation, flexibility and pragmatism, Jiang said.
"China will continue to play a constructive role while maintaining effective communication with all parties on the issue," Jiang said.
The Geneva talks ended Tuesday with both sides agreeing to meet again in late January in Turkey's largest city of Istanbul.
