"I think it's important. I think it will show the readiness of the two parties to move forward and to speed up the process," Zarif told Reuters briefly before his meeting with Kerry in Geneva.
Kerry did not talk to reporters, but had previously told the BBC that he and Zarif needed to "take stock" before Thursday’s round of negotiations.
Tehran has been slapped with sanctions imposed by the UN Security Council, the European Union, the United States and several other countries due to allegations that Iran is trying to produce nuclear weapons under the guise of a program to introduce nuclear power. The Iranian government has repeatedly denied such allegations, stating that Tehran’s nuclear activities are aimed purely at meeting the country’s growing energy needs.
The latest round of talks between Iran and the P5+1 group, held in November in Vienna did not produce a comprehensive deal on Iran's nuclear program and the sides agreed to continue the discussions until July 2015.
