TEHRAN (Tasnim) � Iranian President Hassan Rouhani underlined that possible achievement of a final nuclear deal between Tehran and six world powers will not be the only solution to the whole problems, but would just pave the way for dealing with the challenges more easily.

Addressing a gathering of officials in Tehran on Thursday night, President Rouhani expressed optimism about settling the standoff over Iran's peaceful nuclear program in the diplomatic negotiations between Tehran and the Group 5+1 (Russia, China, the US, Britain, France and Germany).

"The settlement, however, does not mean that all problems will be resolved afterwards, but tens of other problems exist that we should try to resolve as well," he noted.

"Settlement of the nuclear issue will only pave the way for the (Iranian) administration's main push and efforts to resolve the country's problems,� President Rouhani pointed out.

Iran and the Group 5+1 (also known as the P5+1 or E3+3) have been negotiating over the past 22 months to end more than a decade of standoff over Tehran's civilian nuclear program once and for all.

The two sides are busy negotiating in the Austrian capital of Vienna to clinch a final, lasting nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA).

On Tuesday, the parties gave themselves an extra week beyond an end-June deadline to nail down details of the long-awaited accord.
