VIENNA, April 9 (Reuters) - A senior Chinese official at nuclear talks between six world powers and Iran, held in Vienna on April 8-9, said on Wednesday he was optimistic a comprehensive settlement to the decade-old dispute could be found by a July 20 deadline.
“Everyone is aiming at that,” the official, Wang Qun, told reporters after the two-day talks.
He also said that Russia was playing a constructive role in the negotiations despite mounting tensions between Moscow and western governments over Ukraine.
“This is actually definitely helpful to the overall result of the dialogue,” he said.
