Iran and the world powers are braced for a fresh round of talks on the Islamic Republic’s nuclear program, with time is running head of a March 31 deadline.

Iranian Foreign Minister Mohammad Javad Zarif arrived in the Swiss city of Lausanne on Sunday. H e said that Iran and the P5+1 global powers can reach a deal if the six countries show the same political will as Iran.

“In my view, if the opposite side has the same political will as the Islamic Republic of Iran, reaching a solution will not be difficult,” Zarif said upon his arrival in the Swiss city of Lausanne on Sunday.

The Iranian chief nuclear negotiator added that technical aspects and the lifting of sanctions will be the two most important issues that will be discussed in the upcoming round of talks with the P5+1.

“There are two issues that need to be highlighted in this round of talks. One is regarding the issues which have not been resolved yet or those for which there are solutions but the details of which have not been fully discussed,” he said.

On his part, US Secretary of State John Kerry said it was "time to get it done" after 18 months of intense negotiations.

"If peaceful, let's get it done. And my hope is that in the next days, that will be possible," Kerry, in Egypt but due to join the talks in the Swiss city of Lausanne later Sunday, said.

"We believe very much that there's not anything that's going to change in April or May or June that suggests that at that time a decision you can't make now will be made then," Kerry told CBS television.

Iran’s deputy foreign ministers Abbas Araqchi and Majid Takht-e Ravanchi and US Under Secretary of State for Political Affairs Wendy Sherman are scheduled to open the fresh round of talks in Lausanne on Sunday. European Union deputy foreign policy chief, Helga Schmid, will be also present in the negotiations.

Following the talks, Zarif will leave for Brussels, Belgium, on Monday, where he will discuss Iran’s nuclear issue with his German, French and UK counterparts, namely Frank-Walter Steinmeier, Laurent Fabius and Philip Hammond.

EU foreign policy chief, Federica Mogherini, will host the Brussels talks “as part of the ongoing nuclear negotiations with Iran,” her office said in a statement last week.
