Russian and Chinese delegates said all sides had agreed to “expedite” the process.
The negotiating sides want to have something concrete in hand by mid-May, before a monitoring agreement between Iran and the UN nuclear watchdog expires later that month, and ahead of a June 18 presidential election in Iran.
“We hope all parties will sustain the momentum we have already reached in their efforts towards an earliest resolution of this issue before us,” Wang Qun, China’s envoy to the UN watchdog, told reporters after a meeting of senior diplomats, adding that they would reconvene on Wednesday to take stock.
