By Marcus George and James Mackenzie DUBAI/ROME (Reuters) - The protracted dispute over Iran's nuclear program can now be resolved, Iranian Foreign Minister Mohammad Javad Zarif said in remarks released on Tuesday, and world powers should seize an "historic opportunity" to clinch a deal. Iran is to meet the six powers on Wednesday for the third round of negotiations in a month, nearly two weeks after the sides neared an initial accord that would curb Iran's nuclear activity in exchange for limited relief from sanctions. In a five-minute Foreign Ministry video released on Tuesday, Zarif said there was a chance to end the stand-off as long as Western powers dealt with Iran on an "equal footing" and did not seek to impose their will. He later told reporters in Rome before flying to Geneva for the talks that there was "every possibility" of a successful conclusion to the talks provided there was good faith and the political will to resolve problems by all sides.
