Iranian foreign minister Mohammad Javad Zarif said his country and major powers agreed in talks Thursday to reach a deal on the Islamic Republic’s nuclear talks within a year.

The Iranian FM said that the talks, which included a landmark encounter with US Secretary of State John Kerry, were "very good and substantive."

"We agreed to jump start the process so we could move forward with a view to agreeing first on the parameters of the end game ... and move towards finalizing it, hopefully, within a year's time."

"I thought I was too ambitious, bordering on naivete, but I saw that some of my colleagues were even more ambitious and wanted to move faster," Zarif said during a forum of the Asia Society and Council on Foreign Relations.

He said that Kerry was "very positive" and "very committal to leading the process himself on the American side."

Kerry stated "his readiness to lead the discussions to a mutually agreeable solution and I stated President (Sheikh Hasan) Rouhani's commitment to move the process forward," Zarif added.
